In international trade, the safe transportation of equipment is crucial. For sheet metal processing equipment we export, due to its large size and weight, the packaging and loading method directly determines whether the machine can arrive safely and intact at the customer's factory. Depending on the customer's order quantity and equipment size, we typically arrange export shipping using two methods: Less than Container Load (LCL) and Full Container Load (FCL).

1. LCL

LCL is generally suitable for situations where the customer only orders one small sheet metal processing equipment. Since the equipment is not enough to fill a container on its own, in order to reduce the customer's transportation costs, we will combine the goods with other goods in the same container for transportation.

During the LCL process, we will:

1) Wrap the machine with transparent plastic film and place desiccant in the electrical cabinet to prevent moisture and dust during sea transportation;

2) Customize wooden boxes for the machines to ensure they are reliably protected during long-distance transportation;

3) Carefully load the wooden boxes onto the truck using a crane;

4) Cover with rainproof cloth, prevent rain during transportation;

5) The truck will deliver the wooden boxes to the warehouse designated by the freight forwarder, and the freight forwarder will arrange for the LCL shipment.

This can not only reduce the customer's transportation costs, but also ensure that the machine is not damaged during transportation.

2. FCL

When customers order multiple sheet metal processing equipment, or when a single piece of equipment is large, we will use full container shipping.

The full container load shipping process is more rigorous:

1) Wrap the machine with transparent plastic film and place desiccant in the electrical cabinet to prevent moisture and dust during sea transportation;

2) Operate the crane to lift the machine smoothly to the loading area, and assist the forklift to accurately place the front end of the equipment at the container door;

3) The forklift operator skillfully pushes the machine from the container door into the interior and places it in the appropriate position according to the pre-calculated plan to ensure maximum space utilization;

4) Workers attach angle irons to the machine and tie the wire ropes tightly to ensure that the machine will not move or tilt during transportation;

5) Close the cabinet door and lead seal it to ensure that no one else has opened it before the customer receives the machine;

6) The truck will deliver the container to Shanghai Port, where the port will arrange for loading onto the ship and shipping by sea.

 This type of packaging and fixing method is particularly suitable for sheet metal processing equipment with heavy weight and large volume.

Water-cooled screw chillers are the top choice in cooling systems. The market for these chillers will be worth over $4.8 billion in 2025. Big companies buy these chillers because they save energy, can grow with needs, and help the environment. Experts know it is important to watch new trends. Smart technology and new rules help people stay ahead in cooling system ideas.

• Water-cooled screw chiller models use up to 30% less energy than old systems.

• The market gets bigger as chillers show they work well for businesses and factories.

• New ideas like modular design and predictive maintenance make more people use water-cooled screw chillers.

Water-Cooled Screw Chiller Basics

How Water-Cooled Screw Chillers Work

A water-cooled screw chiller cools big buildings and factories. It has two main loops. One is the refrigeration loop. The other is the chilled water loop. The refrigeration loop uses the vapor compression cycle. This cycle lets the refrigerant change between liquid and vapor. It helps absorb heat and then release it. The chilled water loop sends cold water to places that need cooling.

Here is how water-cooled chillers work step by step:

1. The screw compressor takes in low-pressure refrigerant vapor. It squeezes the vapor to make it hotter and under more pressure.

2. The condenser moves heat from the refrigerant to the cooling water. The cooling water goes to the cooling tower.

3. The expansion valve drops the pressure and temperature of the refrigerant.

4. The evaporator takes heat from the chilled water. This cools the water for the building or process.

5. The cycle starts again. This keeps cooling steady and efficient.

This process makes water-cooled screw chillers great for keeping temperatures stable in many places.

Key Components

Every water-cooled screw chiller has important parts. These parts work together to keep things cool:

These main parts help water-cooled chillers work well, last long, and stay reliable in tough places.

Energy Efficiency Advantages

Water-cooled screw chillers are very good at saving energy. They use water to move heat. This helps them cool big buildings well. Using water makes them use less energy. It also helps building owners follow green rules. Experts use SEER, EER, and COP to check how well chillers work. These numbers tell us how much cooling comes from the power used. Lower approach temperatures mean the chiller works better.

Variable Speed Drives

Variable speed drives, or VSDs, help chillers save more energy. VSDs let the compressor change speed when needed. This means the chiller does not always run at full power. It uses less energy when cooling needs are low.

• VSDs stop energy waste by slowing the compressor instead of turning it off and on.

• Studies show VSD chillers use about 11% less energy each year than chillers that run at one speed.

• In big buildings, VSDs can save over a million kilowatt-hours every year.

Tip: VSDs make chillers work better and last longer. They also help save money over time.

Advanced Heat Exchangers

Advanced heat exchangers help chillers move heat faster. New designs, like falling-film evaporators and special tubes, use less refrigerant and energy.

• Hybrid evaporators mix old and new ideas for better cooling and less harm to the planet.

• Stronger tube materials stop rust and help move heat better.

• These changes let chillers reach COP values up to 4.98, showing they save a lot of energy.
  Better heat exchangers also make chillers smaller. This saves space and helps them fit in tight spots.

Innovations in Water Cooled Screw Chiller Technology

IoT and Smart Controls

New water-cooled screw chillers use IoT and smart technology. These systems collect data like temperature and humidity. They also track how much work the chiller is doing. Smart controllers use this information to help the chiller work better. This makes the chiller use less energy and run more smoothly.

• Smart controls can cut energy use by half compared to old chillers.

• One factory in Beijing used 25% less energy in a month after adding smart controls.

• These systems watch the equipment and make small changes to keep things working well.

• This means fewer problems and better control of temperature.

Facility managers need to check their systems before adding IoT. They should pick equipment that works with the new tech. Staff must learn how to use the new system. Regular checks and care, like fixing sensors and checking networks, keep things running well. More people want energy-saving and green systems, so smart chillers are becoming popular.

Note: IoT and smart controls are a big step for cooling systems. They help companies save money and have less downtime.

Sustainable Refrigerants

The industry now wants to use sustainable refrigerants to protect the environment. Old refrigerants like R-134a can harm the planet. New rules say companies must use greener choices. The U.S. SNAP program and some states, like California, limit high-GWP refrigerants in new chillers.

• New refrigerants like R-454B, R-1234ze(E), R-1233zd(E), R-513A, R-515B, and R-32 have much lower GWP.

• Some have GWP close to 1, so they are almost climate-neutral.

• These new refrigerants help chillers work better and follow strict rules.

• Most are not flammable or only a little flammable, so they are safer.

• Top companies now sell chillers with these refrigerants to cut carbon without losing performance.

Natural refrigerants like ammonia, CO2, and hydrocarbons have very low GWP. But they can be harder to use because of safety and cost. Using better refrigerants shows how new ideas and rules are changing cooling.

Scroll Compressor Integration

Adding scroll compressors is another big change in water-cooled screw chillers. Now, some chillers use both screw and scroll compressors together. This is called a hybrid system. It uses the best parts of each compressor.

• Scroll compressors are good when the chiller does not need to work as hard.

• Screw compressors are better when the chiller needs to cool more.

• Hybrid chillers can switch between the two or use both, depending on what is needed.

This design helps chillers use less energy and work better. It also makes chillers more reliable. Hybrid chillers can fit many building sizes and uses. These changes help chillers meet new needs and support a greener world.

Tip: Hybrid systems give more choices and save energy. They are a smart pick for new buildings and upgrades.

Overcoming Challenges

Water Management

Water-cooled screw chillers have some water problems. Corrosion happens when air, minerals, or germs get inside. If different metals touch, they can cause leaks. Dirt and small bits from bad water or dirty towers can block pipes. This makes it harder for the chiller to cool things down. These problems make the chiller less efficient and can break it.

• Condenser tubes can get dirty from things in the water.

• Buildup inside the tubes slows water and makes the chiller work more.

• Cleaning with chemicals or brushes keeps the chiller working well.

How much water chillers use depends on the city. For example, Miami chillers use about 2,010 kGal each year. Chicago chillers use only 549 kGal each year. Some cities charge a lot for water, which can cancel out energy savings. Using more cycles in cooling towers can cut water use by half.

Installation and Maintenance

Good installation and care help chillers last longer. Facility managers use smart tools and IoT sensors to watch temperature, shaking, and how well the chiller works. They look for leaks, clean tubes, and treat water to stop rust and dirt. Workers keep records and follow safety steps, like using lockout/tagout and PPE.

• Each year, they check wires, look for leaks, and test controls.

• Cleaning and water treatment stop clogs and help cooling.

• Training helps workers find problems early and avoid mistakes.

A good maintenance plan helps chillers last longer and break down less often.

The relationship between the temperature rise, temperature, and ambient temperature of the electric motor can be clarified through the following analysis.

1.Basic Definitions

• Ambient Temperature (Tamb​)
  The temperature of the surrounding medium (typically air) where the motor operates, measured in °C or K.

• Motor Temperature (Tmotor)
  The actual temperature of the motor's internal components (e.g., windings, core) during operation, measured in °C or K.

• Temperature Rise (ΔT)
  The difference between the motor temperature and ambient temperature:ΔT=Tmotor−Tamb,Measured in K or °C (since temperature rise is a differential value, the units are interchangeable).

2. Mathematical Relationship

                                                        Tmotor=Tamb+ΔT

• Temperature Rise (ΔT) depends on:

  • Load Conditions: Higher load increases current and losses, leading to greater temperature rise.

  • Cooling Capacity: Heat dissipation design (e.g., fans, heat sinks) or environmental conditions (e.g., ventilation) affect ΔT.

  • Time: During startup or load changes, ΔT varies dynamically until reaching steady state.

3. Key Influencing Factors

• Impact of Ambient Temperature:

  • If TambTamb​ increases, the motor temperature Tmotor rises for the same ΔT.

  • High ambient temperatures may require derating the motor to prevent exceeding insulation limits.

• Limits of Temperature Rise:

  • The motor's insulation class (e.g., Class B, F) defines the maximum allowable temperature (e.g., Class F = 155°C). Thus, the permissible ΔT must satisfy:ΔT≤Tmax−Tamb,where Tmax​ is the insulation material limit.

4. Practical Applications

• Design Phase: The maximum ΔT is determined based on insulation class. For example, a Class F motor (Tmax=155°C) in a 40°C environment has an allowable ΔT of 155−40=115K (accounting for hotspot allowances).

• Operation Monitoring: Abnormal temperature rise may indicate overloading, poor cooling, or insulation degradation.

• Cooling Conditions: Changes in ambient temperature or cooling efficiency dynamically affect ΔT. For instance, fan failure causes a sharp rise in ΔT.

5. Summary of Relationships

• Temperature rise (ΔT) results from the balance between power losses and cooling efficiency, independent of ambient temperature, but the actual motor temperature combines both.

• Ambient temperature sets the baseline for cooling—higher TambTamb​ reduces the allowable ΔT.

• Motor temperature is the ultimate outcome and must comply with insulation limits.

Example

Consider a Class B insulation motor (Tmax=130°C) operating under two scenarios:

• Ambient = 25°C, ΔT=80K: Tmotor=25+80=105°C (safe).

• Ambient = 50°C, same ΔT=80K:Tmotor=50+80=130°C (at limit, requiring load reduction).

This relationship is fundamental to motor thermal protection design and lifespan evaluation.

Choosing the right motor for extreme temperature environments requires careful consideration of several factors to ensure reliability, performance, and longevity. Here’s a step-by-step guide:

1. Define the Temperature Range

High Temperatures: Above 40°C (104°F) can degrade insulation, lubricants, and bearings.

Low Temperatures: Below -20°C (-4°F) can stiffen lubricants, embrittle materials, and reduce efficiency.

Fluctuating Temperatures: Thermal cycling can cause expansion/contraction stresses.

2. Select the Right Motor Type

AC Motors (Induction or Synchronous): Good for moderate extremes but may need modifications.

Brushless DC (BLDC) Motors: Better for wide temperature ranges due to electronic control.

Stepper Motors: Can work in extreme temps but may lose torque at very low temps.

Servo Motors: High precision but may need special encoders for extreme conditions.

3. Insulation Class (For High Heat)

Class B (130°C) – Standard for general purposes.

Class F (155°C) – Better for sustained high heat.

Class H (180°C) – Best for extreme heat (e.g., industrial ovens, aerospace).

Special High-Temp Motors: Some can withstand 200°C+ (e.g., ceramic-insulated windings).

4. Bearing & Lubrication Considerations

High-Temp: Use synthetic oils or dry lubricants (e.g., PTFE, silicone-based).

Low-Temp: Choose low-viscosity lubricants that don’t freeze (e.g., synthetic hydrocarbons).

Sealed Bearings: Prevent lubricant leakage in thermal cycling.

5. Material Selection

Housings: Stainless steel or aluminum with thermal coatings.

Magnets: Samarium-cobalt (SmCo) or neodymium (NdFeB) for high-temp resistance.

Seals & Gaskets: Viton or silicone for flexibility in extreme temps.

6. Thermal Management

Cooling Systems: For high temps, use forced air, liquid cooling, or heat sinks.

Heaters (For Cold): Prevents condensation and lubricant freezing.

Thermal Sensors: Built-in RTDs or thermistors for real-time monitoring.

7. Environmental Protection (IP Rating)

Dust & Moisture: IP65+ for harsh environments.

Explosion-Proof (ATEX/IECEx): Needed if flammable gases are present.

8. Power & Efficiency Adjustments

Derating: High temps reduce motor efficiency; may need oversizing.

Low-Temp Starting: Ensure sufficient torque at startup in cold conditions.

9. Supplier & Testing

Choose manufacturers with experience in extreme-temperature motors.Ctrl-Motor has been engaged in the R&D, production and sales of vacuum motors, high and low temperature motors-related drivers, stepper motors, servo motors, and reducers for 11 years. The high and low temperature motors can be adapted to any extreme conditions from -196℃ to 300℃, and the vacuum degree can reach 10-7pa, we can provide 10^7Gy radiation protection and salt spray protection products. 

Request test data (thermal cycling, cold start, endurance).

Final Tips

Consult Experts: Work with motor suppliers specializing in extreme environments.

Prototype Testing: Validate performance in simulated conditions before full deployment.

Maintenance Plan: Extreme conditions wear motors faster—schedule regular inspections.

By carefully evaluating these factors, you can select a motor that performs reliably in extreme temperatures. 

When using servo motors in low-temperature environments, material selection must carefully consider the effects of cold conditions on mechanical properties, lubrication performance, electrical insulation, and structural stability. Below are key material selection points and design recommendations:

1. Metal Structural Materials

Housing and Bearings:

Aluminum Alloy: Commonly used grades such as 6061 or 7075, subjected to T6 heat treatment to improve low-temperature toughness. Avoid ordinary cast iron (increased brittleness).

Stainless Steel: Grades like 304 or 316 offer low-temperature resistance and corrosion protection, suitable for extreme environments.

Bearing Steel: Use low-temperature-specific bearing steel (e.g., GCr15SiMn) or hybrid ceramic bearings (silicon nitride) to prevent reduced ductility in cold conditions.

Shaft Materials:

Maraging Steel (e.g., 18Ni300): High strength with excellent low-temperature toughness.

Low-Temperature Nickel Steel (e.g., 9% Ni Steel): Alternative for enhanced performance.

2. Lubricants

Low-Temperature Grease:

Base Oil: Polyalphaolefin (PAO) or ester-based oils with lithium complex or polyurea thickeners.

Recommended Products:

Mobilgrease 28 (-40°C to 150°C)

Klüber Isoflex Topas NB 52 (-60°C to 120°C)

Solid Lubricants: For ultra-low temperatures (<-60°C), consider molybdenum disulfide (MoS₂) or graphite coatings.

3. Electrical Components

Coil Insulation:

Magnet Wire: Polyimide (e.g., Kapton) or PTFE-coated wires; avoid PVC (becomes brittle at low temperatures).

Impregnation Resin: Modified epoxy or silicone resins (e.g., Dow Corning 1-2577).

PCB Substrates: High-Tg materials (e.g., FR-4 Tg≥170°C) or polyimide flexible circuits.

4. Seals and Elastomers

Seals:

Nitrile Rubber (NBR): Suitable above -40°C.

Fluorocarbon (FKM) or Silicone Rubber (e.g., modified EPDM): Required below -40°C.

Damping Components: Polyurethane (PU) or specialty silicone, with validation of low-temperature elasticity.

5. Other Critical Materials

Magnets:

Neodymium (NdFeB) magnets exhibit improved magnetic properties at low temperatures but require plating (e.g., Ni-Cu-Ni).

Samarium cobalt (SmCo) magnets for ultra-low temperatures.

Thermal Interface Materials: Low-temperature thermal grease (e.g., Bergquist SIL-Pad 2000) for motor-heatsink interfaces.

6. Design Validation

Material Testing: Conduct impact tests (e.g., Charpy), shrinkage rate, and insulation resistance measurements at target temperatures.

Assembly Tolerances: Account for differential thermal contraction (e.g., aluminum vs. steel CTE ratio ~2:1) via gaps or compensation structures.

Step Cooling Tests: Gradually reduce temperature while monitoring torque fluctuations, bearing resistance, etc.

Targeted material selection and rigorous validation ensure servo motors maintain precision, reliability, and longevity in low-temperature conditions. Practical applications should further optimize based on specific operational factors (e.g., cold-start frequency, load type).

Zhonggu Weike (Shenzhen) Power Technology Co., Ltd. is a National Specialized, Sophisticated, and Innovative ("Little Giant") enterprise specializing in the R&D, manufacturing, and application of special motors for harsh environments, including vacuum, high temperature, cryogenic, deep cryogenic, and radiation conditions. Its product range includes stepper motors, servo motors, radiation-resistant motors, vacuum modules, and vacuum gearboxes, among other standardized series.

The key differences between vacuum motors and standard motors lie in their materials, cooling mechanisms, and environmental adaptability. The former is specifically designed for vacuum environments, employing specialized processes to achieve low outgassing, high-temperature resistance, and contamination-free operation.

Material and Process Differences

1、Housing and Component Materials

Vacuum motors use specialized alloys or stainless steel housings resistant to high-pressure vacuum conditions, minimizing deformation to ensure positioning accuracy (e.g., neodymium magnets have lower temperature limits, while vacuum motors can withstand up to 300°C).

Coils utilize high-quality insulating materials and undergo processes like vacuum degassing and vacuum impregnation to reduce outgassing and prevent contamination in vacuum environments.

2、Lubricant Selection

Standard motor lubricants may volatilize or harden in a vacuum, leading to failure. Vacuum motors use specialized lubricants resistant to extreme temperatures, ensuring reliable operation.

3、Insulation and Voltage Resistance

Standard motors: Insulation is designed for atmospheric pressure, with no need for high-voltage breakdown protection.

Vacuum motors:

Enhanced insulation: Vacuum environments lower breakdown voltage, requiring materials like polyimide film or ceramic insulators.

Arc-resistant design: Prevents vacuum arcing from damaging components.

Structural Sealing

Standard motors: Typically require only dust/water resistance (IP ratings).

Vacuum motors:

Vacuum sealing: Uses metal gaskets (e.g., copper seals) or welded structures to prevent gas leakage.

Particle-free design: Avoids releasing internal debris into the vacuum.

Cooling and Environmental Adaptability

1、Cooling Mechanism

Standard motors rely on air convection, while vacuum motors dissipate heat only via conduction and radiation. Vacuum motors optimize cooling through thermal path enhancements and integrated temperature sensors.

2、Extreme Temperature Tolerance

Standard motors: Max ~130°C; prolonged exposure causes torque loss or demagnetization.

Vacuum motors: Withstand 200°C+ continuously, with peak tolerance of 280–300°C.

Functionality and Applications

1、Contamination Control

Vacuum motors use low-outgassing materials and sealed designs, making them ideal for semiconductor manufacturing, optical instruments, and other ultra-clean environments. Standard motor organics (e.g., grease, adhesives) can pollute vacuums.

2、Application Fields

Vacuum motors:

Aerospace (satellite mechanisms, solar array drives)

Semiconductor (wafer-handling robots)

Vacuum coating machines, particle accelerators

Standard motors: Industrial machinery, household appliances, automotive (atmospheric conditions).

Note: Using standard motors in vacuums requires additional sealing and cooling systems, increasing complexity. The core advantage of vacuum motors is their built-in compatibility with extreme environments.
