Troubleshooting Water Cooled Screw Chillers: Common Faults and Fixes

You might have high-pressure trips, refrigerant leaks, or compressor overload when using a water cooled screw chiller. Fast troubleshooting helps lower downtime and expensive repairs. Regular checks and preventive maintenance help find problems early. Knowing your water cooled chiller well helps you see issues before they get worse.

Water Cooled Screw Chiller Faults

• High Pressure

High pressure alarms can happen in your water cooled screw chiller. Air or other gases in the system can cause this. Too much refrigerant or a dirty condenser can also be the reason. If the cooling water is too warm, pressure goes up fast. Low water flow makes pressure rise too. Dirt in pipes or a broken water pump can cause high pressure faults. To fix these, clean the condenser and check water flow. Adjust the refrigerant level if needed.

Tip:If you see high pressure, always look for dirt on the condenser surface.

• Low Pressure

Low pressure is another problem you might see. This can happen if there is not enough refrigerant or if there is a leak. Cold weather can make water and oil colder, causing low pressure alarms. Blocked filters or pipes can also lead to this. A bad expansion valve or electrical relay can be the cause too. Check for leaks and clean the filters. Make sure all valves are working right.

• Water Flow Loss

Water flow loss is a common fault in water cooled chillers. This happens if the water pump stops or pipes get blocked. Air in the system can also cause it. Low water flow can make the chiller shut down or work poorly. Always check pumps and pipes for blockages or leaks.

• Refrigerant Leaks

Refrigerant leaks are serious in water cooled screw chillers. Leaks make cooling worse and use more energy. Some refrigerants can hurt the environment if they escape. Check for leaks often and fix them fast. This helps avoid high costs and protects the environment.

• Oil System Issues

Oil system issues can harm your chiller. Oil leaks, dirty oil, low oil pressure, or hot oil are common faults. These problems lower lubrication and can make the compressor overheat or wear out. Check oil levels often and change oil when needed. Clean or replace oil filters as well.

• Electrical Problems

Electrical problems often cause chiller faults. Loose wires, bad relays, or blown fuses can stop the chiller. If your chiller will not start, check the electrical panel first. Make sure all wires are tight and replace any broken parts.

• Noise and Vibration

Strange noises or vibration can mean mechanical problems. Loose screws, unbalanced fans, or pipes not fixed well can cause rattling or banging. If you hear loud or repeating noises, look for loose parts or debris. Finding these problems early helps stop bigger faults and keeps your chiller working well.

Chiller Troubleshooting Steps

Troubleshoot Pressure Issues

Pressure problems in your chiller can cause shutdowns or poor cooling. You can follow these steps to find and fix pressure faults:

1. Check all valves. Make sure refrigerant valves are open. Isolation valves should stay closed unless you need them for repairs.

2. Look at the water flow. The water pumps must run well. Both the condenser and evaporator need enough water flow to keep the chiller cool.

3. Inspect the condenser coils. Dirt or debris can block heat transfer and raise pressure.

4. Watch the condenser fan. The fan should spin in the right direction and work without stopping.

5. Use the chiller manual. Find alarm codes and follow the troubleshooting methods listed.

6. If you see high pressure alarms, check for air or non-condensable gases in the system.

7. Ask a qualified technician to test high pressure switches, contactors, and relays if you cannot find the problem.

Tip:Clean the condenser coils often. This simple step prevents many pressure issues.

Troubleshoot Water Flow

Water flow problems can stop your chiller or make it noisy. Use these troubleshooting methods to restore proper flow:

1. Read all safety instructions before you start.

2. Unplug the chiller and drain the water. Remove hoses and tilt the unit to empty it.

3. Take out the cartridge filter. Soak it in water for two minutes, then put it back.

4. Check every hose and fitting for air leaks. Use Teflon tape and tighten clamps to stop air from getting in.

5. Prime the system. Disconnect the water inlet hose, lift it up, and pour water until no bubbles come out of the outlet.

6. Start the chiller for one minute. Watch for steady water flow and no bubbles. Repeat priming if needed.

7. You can flush the system with a garden hose to clear air pockets.

Troubleshoot Refrigerant Problems

Refrigerant faults can cause poor cooling or strange noises. Follow these troubleshooting methods to find the cause:

1. Watch for signs like weak cooling, ice on coils, or odd sounds.

2. Look for leaks or airflow problems around the chiller.

3. Use manifold gauges to check refrigerant pressures.

4. Test for leaks with an electronic detector or UV dye.

5. Inspect the expansion valve for blockages. Make sure superheat settings are correct.

6. Check the evaporator coil for dirt or ice. Good airflow is important.

7. Look at the filter drier and pipes for restrictions.

8. Measure suction and discharge pressures at the compressor. Listen for odd noises.

9. Check sensor readings. Replace or calibrate sensors if they are wrong.

10. Do regular maintenance. Clean coils and filters, and check for leaks often.

Safety Alert:Always use the right recovery cylinder for each refrigerant type. Never overfill cylinders. Use EPA-certified tools and keep records of all refrigerant handling.

Troubleshoot Electrical Issues

If your chiller cannot start or stops working, electrical faults may be the cause. Try these troubleshooting methods:

• Open the electrical panel and look for loose wires or burned parts.

• Check all relays, fuses, and contactors. Replace any that look damaged.

• Make sure the power supply is correct and all phases are connected.

• Use a multimeter to test voltage and current at key points.

• If you find a problem you cannot fix, call a licensed electrician.

Tip:Always close the electrical panel after checks to keep dust and moisture out.

Troubleshoot Noise and Vibration

Strange noises or shaking can mean loose or broken parts. Use these steps to troubleshoot:

• Listen for rattling, banging, or humming sounds.

• Check all screws, bolts, and mounts. Tighten any that are loose.

• Inspect fans and pumps for balance. Replace or repair if needed.

• Look at pipes and hoses. Secure them to stop vibration.

• If noise continues, ask a technician to check for deeper mechanical issues.

Chiller Troubleshooting Checklist

You can use this checklist for quick chiller troubleshooting. It helps you spot problems early and decide when to call a professional.

This stops cracks, warping, and other problems. Studies show that controlling temperature makes metal harder and stronger. It also helps the metal bend without breaking. It uses less energy and saves money too. A good industrial process chiller keeps the workplace the same all the time. This makes every finished product better and more exact. Companies use these chillers for tough jobs and to work fast.

Key Takeaways

• 10 HP process chillers keep metal finishing cool and steady. This stops cracks, warping, and weak metal from happening. These chillers have strong parts like stainless steel tanks and copper coils. These parts help them last a long time and work well. Microcomputer controls keep the temperature just right. This makes products better and saves energy. They do not need much maintenance. They have safety features to protect machines and stop breakdowns. 10 HP chillers are flexible and save energy. They are easy to move and good for many metal finishing jobs.

10 HP Chiller Features

A process chiller is a machine that cools things down in factories. The OUMAL OMC-10A 10 HP chiller is great for metal finishing. It uses air-to-water cooling and has a copper coil that is strong. The tank is made of stainless steel, so it does not rust and keeps water clean. Workers can use the microcomputer control panel to set and check the temperature. This chiller keeps the temperature steady, which is very important for metal finishing.

Note: The OMC-10A model uses good parts like Schneider electrical components. These parts help the chiller stay safe and work well.

The table below lists the main features of 10 HP process chillers used for metal finishing:

Copper coils and stainless steel tanks help the chiller last a long time. These materials stop rust and keep the chiller working well. The OMC-10A chiller can cool with 27 kW (7.7 tons), which fits many metal finishing jobs. It uses about 9.2 kW of power, so it is good for saving energy and cooling.

How Process Chillers Work

Process chillers use a simple cycle to cool things down. First, the refrigerant goes into the evaporator. It takes heat from the process fluid, like the liquid used in metal finishing. The refrigerant turns into a gas. The compressor pushes this gas to a higher pressure and temperature. Then, the gas goes to the condenser. In air-cooled chillers, the condenser lets out the heat into the air, and the gas turns back into a liquid. The liquid goes through an expansion valve, which makes it cooler and lowers the pressure. The cycle starts again.

1. The refrigerant takes heat from the process fluid in the evaporator.

2. The compressor makes the refrigerant gas hotter and under more pressure.

3. The condenser lets out heat to the air, turning the gas into a liquid.

4. The expansion valve cools the liquid, and the cycle repeats.

Microcomputer controls help keep the temperature steady. They let the chiller keep the water temperature close to the same, usually within ±1°C. This is important for process chillers in metal finishing. The OMC-10A chiller uses these controls to keep things safe and make sure the results are good.

Metal Finishing Cooling Needs

Temperature Control Challenges

Keeping things cool is very important in metal finishing. Jobs like anodizing, plating, and quenching need steady temperatures. If the temperature changes a lot, metal can bend or break. It might also get weaker. Workers have some problems when they try to keep the right temperature:

• Some materials, like plastics or MDF panels, can bubble or crack if they get too hot.

• Certain parts must stay within a set temperature. If it gets too hot, these parts can bend or break.

• Some parts, like refrigerant compressors, need careful heating and cooling.

• Metal parts with different thicknesses can heat up unevenly. This makes it hard to keep the whole part at the right temperature.

• Big, heavy parts need more heat to process. This can slow down work and cost more money.

A chiller helps by keeping the temperature steady. The 10 HP chiller uses sensors to check for temperature changes during busy times. If the temperature goes up, the chiller sends coolant through heat exchangers to cool things down. When the temperature is right, the system stops sending coolant. This automatic control keeps everything safe and working well.

Application Examples

Keeping the temperature steady helps protect products and machines. Here are some ways bad temperature control can hurt metal finishing:

1. If the temperature changes, metal can get bigger or smaller. This can cause size mistakes.

2. High heat can change the metal’s surface or inside. The metal can get softer or weaker.

3. Too much heat can burn or discolor the metal. It can also cause other surface problems.

4. Hot conditions can wear out tools faster. Grinding wheels can get damaged too.

5. Bad temperature control can leave stress in the metal. This can make it bend or break later.

A 10 HP chiller gives the cooling needed to stop these problems. By keeping the temperature in a small range, the chiller helps each job go well. This means better products, less stopping, and longer machine life. Good chillers also help make more products. They help every finished product meet high standards.

Benefits of 10 HP Chillers

Efficiency and Reliability

10 HP chillers save energy and work well in metal finishing. They have special compressors that change speed when needed. This helps keep the temperature steady and uses less energy. Many factories say their energy use drops a lot after using these chillers. The system now uses only about one-third of the energy older chillers used. The pumps also use less power, so more energy is saved.

Factories have fewer problems because the chiller keeps water temperature and pressure steady. This helps protect machines and makes products better.

Chillers with variable-speed compressors do not turn on and off too quickly. This means less stress on the compressor and it lasts longer. Electronic safety features help stop problems before they happen. Soft-start controls help the system start gently and protect the parts. These things make the chiller good for busy factories.

These chillers are small and fit well in crowded places. Wheels make it easy to move them around. The system uses closed water loops, so the water stays clean and needs less care.

Key reliability features include:

• Steady temperature for better results

• Fewer breakdowns because of safety features

How They Work

Water Cooled Screw Chiller

A water cooled screw chiller gives strong cooling for big places. It takes heat from your building and puts it into water. The water goes through pipes to a cooling tower. The cooling tower lets the heat out into the air. You find these chillers in hospitals, factories, and big offices. They are good for places that need a lot of cooling. Groups like ASHRAE 90.1 and ARI say these chillers work well for big jobs and save energy. New models use special drives and better refrigerants. This helps save more energy and follow strict rules.

Air Cooled Chiller

An air cooled chiller is good if you want something simple. It uses fans to blow air over coils to cool the refrigerant. The heat goes straight into the outside air. You do not need a cooling tower or extra water. These chillers are good for small buildings or places with little water. They are easier to put in and take care of. But they might use more energy, especially when it is hot outside.

Main Differences

The biggest difference is how each system gets rid of heat. Water cooled screw chillers use water and cooling towers. Air cooled chillers use air and fans.

Here is a quick look at how they work:

A water cooled screw chiller gives better efficiency and heat transfer. Air cooled chillers are easier to set up and cost less at first. But they may not work as well in big or busy places.

Comparison Factors

Energy Efficiency

You want to use less energy and save money. Water cooled screw chillers are usually more efficient. They use water to move heat, which works better than air. Studies show that if you run chillers together in a smart way, you can cool up to 93 kW more each hour. This saves a lot of energy over time. In big buildings, smart controls help cut energy use by over 11%. They also make the Coefficient of Performance (COP) go up by more than 21%. This means your system does more work for each unit of electricity. Air cooled chillers can save energy too if they have variable-speed fans and smart controls. But they are not as efficient as water cooled chillers, especially when it is hot outside.

Costs

You need to think about both the starting cost and the cost to keep it running. Water cooled screw chillers cost more to put in. You need a cooling tower, pumps, and extra pipes. The base cost is about $1,000 for each ton of cooling. Air cooled chillers cost less to install because they do not need extra water systems. But they may use more electricity, especially in hot or dry places. Here is a quick look at cost factors:

Maintenance

You want a system that is easy to take care of. Water cooled screw chillers need more work. You have to check the cooling tower and clean the pipes. You also need to watch for scale or rust. These systems have more moving parts. Air cooled chillers are simpler. You just clean the coils and check the fans. This means less downtime and fewer repairs. If you want less work, air cooled chillers are easier to handle.

Capacity

If your building needs a lot of cooling, water cooled screw chillers are better. They can handle big loads and work well in hospitals, factories, or tall office buildings. They can run for long hours without losing power. Air cooled chillers are good for smaller buildings or places that do not need as much cooling. They may not work as well if you try to cool a big space or run them all day.

Climate Suitability

The weather where you live matters. Water cooled screw chillers work well in any climate, even if it is hot or humid. They do not lose much efficiency when it gets hot outside. Air cooled chillers work best in places that are not too hot. When it is hot, they use more electricity and do not cool as well. Studies show that in Mediterranean climates, smart fan controls can save up to 12% on electricity. In subtropical areas, advanced controls help air cooled chillers save energy. But water cooled chillers still work better in high heat.

Space and Noise

You need to plan where to put your chiller. Water cooled screw chillers need a mechanical room and space for a cooling tower. They run quietly, which is good for hospitals or offices where noise matters. Air cooled chillers go outside. They need open space and make more noise because of their fans and compressors. If you do not have much indoor space or do not mind noise, air cooled chillers may work for you.

Lifespan

You want your chiller to last a long time. Water cooled screw chillers usually last longer—often 20 to 30 years—if you take care of them. Their parts wear out slowly because they run in steady conditions. Air cooled chillers last about 15 to 20 years. Weather and temperature changes can make them wear out faster.

If you want a quiet, long-lasting, and efficient system for a big building, water cooled screw chillers are often best. For smaller spaces or places with little water, air cooled chillers are simpler and cost less.

Ⅰ.Valve Bag Production Upgrade: The Gachn Group AI Vision Inspection Bag Making Machine 3.0 delivers both efficiency and precision.

(Gachn group valve bag making machine working process diagram)

Valve bags, due to their strong sealing properties and high adaptability to automation, have become the preferred choice for industries such as cement, chemicals, and mineral powders. However, traditional production processes continue to plague businesses with low manual bag picking efficiency, high scrap rates, and difficult cost controls. Gachn Group's AI-powered visual inspection valve bag making machine 3.0 addresses these pain points with technological innovation.

Core technological highlights redefine valve bag production standards.

1. AI visual inspection replaces manual inspection.

The standard raw material visual inspection system uses high-precision cameras and AI algorithms to automatically identify defects such as holes, splices, and warp and weft deviations in the base fabric, as well as skewed corners, offset bottom stickers, and poor overlaps in finished bags, with a rejection rate as low as 0.05%. This eliminates one or two bag-picking workers per production line, completely resolving the industry challenges of "difficulty recruiting and inconsistent quality inspection."

2. Fully servo-controlled, delivering both speed and flexibility.

The machine boasts a stable operating speed of 120-130 bags per minute, far exceeding traditional equipment. It supports "one-click size change," easily switching between various sizes, including 380-910mm (woven bag width) and 80-200mm (valve port length), eliminating complex debugging and increasing flexibility in batch production.

In the bag transfer process, the Gachn Group utilizes a proprietary vacuum suction bag steering mechanism, enabling high-speed, vertical bag transfer for rapid and stable operation. Unlike the "claw-type" bag steering mechanisms used by other manufacturers, Gachn Group possesses its own core technology and intellectual property, avoiding patents held by renowned international equipment manufacturers and eliminating the risk of intellectual property infringement lawsuits.

The triangular bag opening mechanism is a further highlight, lacking consumable suction cups, significantly reducing ongoing maintenance costs. This mechanism utilizes a combination of negative pressure and a conveyor system to efficiently open the bag bottom while reducing noise and ensuring efficient and stable operation. Similarly, this proprietary core technology avoids international patents, eliminating the risk of intellectual property infringement lawsuits and providing peace of mind for manufacturers.

In terms of suction roller transfer, the bottom tape belt conveyors used by other valve bag making machines on the market are prone to bending, resulting in scrap. Furthermore, the higher the production speed, the more severe the kinking problem becomes. The belts also wear easily, making replacement difficult. Gachn Group's innovative suction roller conveyor mechanism is less prone to corner bending, significantly improving bag yields, enhancing equipment stability, and reducing production costs. This feature is unique to Gachn Group and is patented.

In addition, Gachn Group utilizes a professionally designed heat-sealing welding mechanism and unique technology, equipped with three hot air mechanisms, to ensure uniform air blowing and consistent dimensions. Servo-controlled switching of the air blow reversing axis allows for precise control of the welding on/off timing. Compared to other manufacturers' pneumatic cylinder control mechanisms, this system offers higher welding quality, precise adjustment of the air blow angle, and flexible adjustment of the heat seal width without requiring downtime, significantly enhancing production flexibility and efficiency.

The bag-making speed reaches a stable 130 bags/minute, with a maximum operating speed of 140 bags/minute.

Gachn Group's new-generation FK008-III valve bag bag-making machine integrates a visual inspection and waste removal system with core bag-making technology, creating a truly fully automated AI-powered closed-loop production system. Equipped with a 4K line-array infrared high-speed industrial camera and a black-and-white high-speed industrial camera, the visual inspection system accurately detects cosmetic defects in bags at a speed of 120 bags/minute. With a waste rejection rate of ≥96.5% and a false rejection rate of <0.15%, it enables real-time monitoring and intelligent screening of bag quality. Its detection logic is efficiently integrated with the core bag-making technology. When the visual system identifies a defective bag, a signal is instantly fed back to the bag-making unit's servo control system, triggering a cutting mechanism to precisely separate the defective bag. Simultaneously, the bag transfer unit's vacuum suction and dual servo drive systems immediately adjust the conveying rhythm to ensure that subsequent qualified bags are not affected.

Superior Equipment Configuration Ensures Stable and Efficient Operation.

If replacing the bedknife it is important to use the following procedure:

1. Remove the bedbar from cutting unit.

2. Remove the screws from the bedbar using a socket wrench and a bedknife screw tool. Discard the screws.

3. Use a scraper to remove all rust, scale and corrosion from bedbar surface.

4. Lightly oil the bedbar surface before installing the bedknife.

5. Make sure that screw threads in the bedbar are clean.

IMPORTANT: Do not use an impact wrench to tighten the screws into the bedbar.

6. Use new screws to secure bedknife to bedbar. Apply antiseize lubricant to the threads of new screws. Do not apply antiseize lubricant to the taper of the screwheads.

7. Install all screws but do not tighten.

8. Using a torque wrench and bedknife screw tool, tighten the 2 outer screws to 10 in- lb (1 N-m).

9. Working fromthe center of the bedknife toward each end, tighten screws from 200 to 250 in- lb (23 to 28 N- m).

10. Grind the bedknife after installing it to the bedbar.

Since there can be variations in the mounting surface of the bedbar, it is necessary to grind the bedknife after installing it to the bedbar.

When grinding the bedknife, remove only enough material to make sure the top surface of the bedknife is true. Be careful not to overheat the bedknife. Remove small amounts of material with each pass of the grinder. Also, clean and dress grinding stone often during the grinding process.

Because the top grind angle on bedknives is critical for edge retention, and therefore after- cut appear ance,Using special service tools for accurately measuring the top grind angle on all bedknives.

IMPORTANT: Do Not grind the bedknife below it’s service limit. Operating the cutting unit with the bedknife below the service limit may result in poor after- cut appearance and reduce the structural integrity of the bedknife for impacts.

A lead-in chamfer provides a softened entry for the leading side of the reel blade helix as it approaches the bedknife. This helps eliminate rifling caused by heavy contact and vibration. A lead- in chamfer is ground into all new Reelmaster bedknives. The original chamfer should last for the first 40%of the bedknife service life. Check and re-grind the lead- in chamfer as necessary.

The idea is to get a grind in place without spending a lot of time making sure it is exact. Using a file to make the lead-in is a perfectly acceptable method. It is important not to make the lead-in too long or you will notice that there is a streak left behind at the edge of the cutting unit as the reel will not cut well in the area

of the grind or may adversely affect the overlap area.

The Edge Max bedknife includes a leading edge of harder steel.

The Edge Max bedknife Holds an edge twice as long as a standard bedknife, and reduces the need for adjustments, backlapping and grinding.

Set the bedknife to reel adjustment on an Edge Max bedknife as usual. Light contact while running on the ground.

There are no other special requirements.

A dull knife must be sharpened.

If backlapping is part of your maintenance practice, be prepared to backlap for two to three times the amount of time as compared to a standard bedknife. Front face grinding is acceptable in moderation.

Any facing or grinding must be done with exacting tolerances. Do not use a hand held grinder

Using a diamond grinding wheel is recommended to prevent overheating or damaging the bedknife edge while grinding.

Dress the stone more frequently. Before starting, and at least once during grinding. One pass to dress. Multiple passes will cause the stone to load up.

When grinding, remove smaller amounts of material

(a shallower cut).

Expect a different spark pattern.

Bedknife design must allow for maximum material to dissipate heat and yet allow the remaining uncut grass under the bedknife.

Unfortunately, there is no set rule for space left under the knife, nor can there be. This is due primarily to surface density and turf conditions. There is no measurable plane that works, other than, your mower, in your turf.

The only thing that is absolute is that while on the bench, the bedknife can not touch the height of cut adjusting tool. There must be a reasonable space between the bedknife and height of cut adjusting tool.

To look at that in a different manner, place the cutting unit on a table resting on the rollers so as you can look at the end of the cutting unit. The bedknife can not touch the table top. This is the absolute! Everything else depends on the agronomic conditions of the turf.

Listed here are popular Greens mower bedknives and their recommended operating range.

Due to the height of cut variations on a fairway and the requirements of cutting conditions there is another line of bedknives for the fairway or higher height of cut ranges.

Green speed is an important indicator of green quality, and many golf courses face the challenge of not meeting the required speeds for different tournaments. Here are some short-term effective methods to enhance green speed:

Adjust Mower Bed Knife Angle: Increasing the front angle of the bed knife can improve post-mowing green speed and enhance the smoothness of the cut. A high-quality bed knife for mowers can make a significant difference in achieving better cutting results.

Temporary Cleansing: By raising the height of the grooming brush, you can avoid disturbing the soil while also increasing the gap between the reel and the bed knife to reduce equipment load and improve cut uniformity.

Change Cutting Direction: Utilizing a cross-cutting pattern and reverse mowing can enhance upright grass growth and ensure a level hitting surface, thus increasing speed.

Moisture Control: Reduce automatic irrigation and opt for manual watering to prevent localized wetness, helping to keep the greens dry and speedier.

Adjust Mowing Height: Properly lowering the mowing height according to the 1/3 cutting rule can avoid damaging the turf while enhancing speed.

Adjust Mowing Frequency: Increasing the frequency of mowing, especially by mowing twice a day during high-speed demands, improves grass density and smoothness.

Optimize Mowing Speed: Choosing the right mower and blade type, and ensuring the mowing speed matches the grass height, can enhance cutting quality. A precision bed knife for golf course greens is crucial in ensuring a clean and even cut for better results.

Maintain Sharp Blades: Keeping the bed knife and reel sharp, along with proper blade spacing, ensures a clean cut and improves green speed. Regular sharpening is essential for maintaining the effectiveness of a durable bed knife for golf course mowers.

Rolling: Rolling the greens is an effective and safe method for quickly improving speed; studies show significant differences in speed before and after rolling.

Implementing these strategies can effectively increase green speed to meet tournament requirements.
