In the heavy industry, cold assembly freezers (also called industrial freezers or cryogenic freezers) are used to cool and store large workpieces or materials to meet specific process requirements. This equipment is often used in metal processing, mold manufacturing, aerospace and other fields to ensure the performance and processing quality of workpieces under low temperature conditions.

1. Wide temperature range:

• Temperature range: usually from -20°C to -80°C, some advanced models can provide lower temperatures, such as -100°C.
• Such a temperature range can meet the needs of different materials and processes.

2. High-precision temperature control:

• Adopt PID controller or other advanced temperature control technology to achieve high-precision temperature control.
• The control accuracy is usually ±1°C or less, ensuring temperature stability and consistency.

3. Fast cooling capability:

• Refrigeration system: quickly reduce the temperature to the set value through an efficient compressor refrigeration system.
• Pre-cooling function: Some models have a pre-cooling function, which can reduce the temperature to an extremely low temperature in a short time.

4. Large-capacity storage:

• Volume: According to the size and quantity of the workpieces, choose a freezer with a suitable volume, usually ranging from several hundred liters to several cubic meters.
• Multi-layer shelves: Provide multi-layer shelves or pallets to facilitate the storage of workpieces of different sizes and shapes.

5. Safety protection measures:

• Overtemperature protection: Automatically cut off the power supply when the temperature exceeds the set value.
• Overpressure protection: Prevent the system pressure from being too high.
• Leak detection: Detect whether there is a leak in the system.
• Emergency stop button: Quickly stop the system operation in an emergency.

1. Metal processing:

• In the metal cutting process, low temperature can reduce tool wear and improve processing accuracy and efficiency.
• For example, deep cryogenic treatment can improve the hardness and wear resistance of metal materials.

2. Mold manufacturing:

• In the mold manufacturing process, low temperature can reduce the thermal stress of the mold and extend the service life of the mold.
• For example, cryogenic treatment can eliminate residual stress inside the mold.

3. Aerospace:

• In the processing and storage of aerospace materials, low temperature can ensure the performance and stability of the materials.
• For example, some composite materials need to be stored under low temperature conditions to maintain their properties.

4. Scientific research and laboratories:

• In scientific research and laboratories, low temperature can be used to preserve and study various materials and samples.
• For example, biological samples, chemical reagents, etc. need to be stored under low temperature conditions.

1. Temperature range:

• Make sure that the equipment can cover the required temperature range (-20°C to -80°C or lower).

2. Temperature control accuracy:

• Choose a system with high-precision temperature control, such as a PID controller, to ensure temperature stability.

3. Refrigeration capacity:

• Choose a refrigeration capacity suitable for the size and number of workpieces to ensure rapid cooling and temperature maintenance.

4. Storage capacity:

• Choose a storage capacity suitable for the size and number of workpieces, usually ranging from hundreds of liters to several cubic meters.

5. Safety:

• Ensure that the system has multiple safety protection measures, such as over-temperature protection, over-pressure protection, leak detection, etc., to ensure the safety of operators and equipment.

6. Maintenance cost:

• Choose a system that is easy to maintain and operate to reduce long-term operating costs.

By selecting the appropriate refrigeration capacity and storage capacity, a high-precision temperature control system, and multiple safety protection measures, precise temperature control can be achieved to improve the processing quality and performance of the workpiece. It is recommended to consult a professional equipment supplier or engineer before purchasing to ensure that you choose the freezer that best suits your needs.
