Low temperature chillers typically use semi enclosed piston compressors, which have the following advantages:
1. The piston compressor has a wide range of applicable pressures and can be designed for low pressure, medium pressure, high pressure, and ultra-high pressure. Moreover, at equal speeds, when the exhaust pressure fluctuates, the displacement of the piston compressor remains basically unchanged.
2. The compression efficiency is high, and the process of compressing gas with a piston compressor belongs to a closed system, resulting in high compression efficiency.
3. Strong adaptability, piston compressors have a wide range of displacement, and the impact of gas density on compressor performance is not as significant as that of speed compressors, making them more suitable for low-temperature operating units.
Requirements for the use of low-temperature air-cooled chillers
1. According to different usage temperatures, there are different requirements for cooling media. It is recommended to use ethylene glycol solution from 0 to 40; -Low temperature thermal oil is recommended for temperatures below 60 degrees, and flammable liquids such as alcohol are not recommended.
2. The installation of low-temperature chiller units should be as close as possible to the equipment in use, because the farther away the distance, the greater the pump head and the higher the motor power, which increases the load on the unit. The pipeline must be insulated and protected to minimize the loss of cooling capacity.

Q: Can this low-temperature chiller use a 3-phase 220V 60Hz power supply?
Answer: Yes, the compressor motor can support a wide range of power supply standards and may also be controlled by adjusting the input/output power through a frequency converter.
