Circulating low temperature refrigeration system is also called a low-temperature chiller. It usually refers to a unit with a water temperature of -60°C to 5°C. It is generally used in various industrial production lines that require low temperatures. In fact, low-temperature units are a large category. If subdivided, they are divided into water-cooled and air-cooled types according to different cooling forms. According to different compressors, they are divided into screw type, scroll type and piston type.

Characteristics of circulating low temperature refrigeration system

1. Reliable performance, energy saving and environmental protection

The compressor of the circulating low temperature refrigeration system adopts a semi-closed screw type and has built-in advanced components such as oil filter, oil separator, safety pressure reducing valve, suction filter and protection module to ensure stable performance and no leakage during the operation of the equipment. Low energy consumption.

2. Multiple refrigerants available

In addition to R22 refrigerant, environmentally friendly refrigerants such as R134A or R407C can also be selected according to customers’ different usage scenarios and needs.

3. Low noise and smooth operation

Since the compressor of the circulating low temperature refrigeration system consumes a large amount of lubricating oil and supplies oil with a low pressure difference, the lubricating oil has high oil separation efficiency and can absorb the noise of the unit’s operation. In addition, the circulating low temperature refrigeration system uses a high-precision and high-stability compressor, so the unit runs smoothly, has low vibration, and the noise is much smaller, effectively reducing interference to the outside world and improving the unit’s operational stability.

4. High automation, easy to operate

The circulating low temperature refrigeration system has a built-in microcomputer automatic control system, which can directly control the unit through the touch screen to ensure the safety and stability of the unit, which reflects its advanced nature. The display screen will present each parameter setting value, operation status, alarm status and historical records of the unit in real time, making it easy for the operator to understand and operate.

5. Easy to install, simple and fast

When installing the circulating low temperature refrigeration system, you only need to connect water and electricity on site, and charge an appropriate amount of refrigerant into the equipment. After debugging according to the set values, it can be put into operation. No traditional equipment is required, and a lot of on-site installation work is also eliminated. .

6. High heat exchange efficiency

The circulating low temperature refrigeration system has been updated and optimized to optimize the internal heat exchange system. This change has greatly improved the heat exchange efficiency of the equipment.

7. Low consumption, saving refrigerant

The circulating low temperature refrigeration system uses a dry evaporator, which not only greatly reduces the amount of refrigerant injected, but also eliminates the need for an oil pump and makes oil return simple.

8. Long service life

With multiple built-in compressors, the circulation circuits of each compressor can operate independently without interfering with each other, extending the service life of the unit.

9. Strong compatibility and wide application range

In addition, the circulating low temperature refrigeration system needs to be cleaned regularly, at least once a month. Especially if it is going to be out of service for a long time, it must be cleaned carefully from the inside out. For example, major components such as refrigeration compressors and coolers, as well as components such as filter surfaces and pipelines that are prone to residual impurities. Insufficient cleaning will cause excessive stains to accumulate in the equipment, affecting the efficiency of the equipment. After cleaning, it is best to seal and store the low-temperature unit to prevent dust and impurities from entering.
