product description:

1. The single-head water-cooled screw refrigerator unit uses a semi-closed and high-efficiency screw compressor with built-in safety protection, low noise, energy saving and durability.

2. The high-efficiency shell and tube heat exchanger adopts the latest technology, is small in size, has high performance, and is not easily damaged. It has a built-in high-pressure liquid reservoir to achieve no loss in the system and ensure smooth oil return.

3. The chiller condenser adopts water cooling method and can be used on various systems. It is not limited by ambient temperature, has stable performance and easy maintenance.

4. The single-head water-cooled screw freezer is equipped with a single-chip control system, built-in compressor drying filter, expansion valve, maintenance hand valve interface and other devices to ensure reliable and safe operation of the machine and facilitate maintenance.

5. Equipped with a liquid injection system, it can effectively reduce the compressor oil temperature and greatly improve the efficiency of the unit under low temperature conditions.

6. The imported PLC human-machine operation interface is an LCD touch screen with graphic display, which is easy to operate and is available in Chinese and English. It is equipped with RS485 national standard communication interface, which can be connected to the DCS system and can be connected to the entire factory automatic control network to facilitate remote control and monitoring.

7. Automatically detect the outlet water temperature or return water temperature, and automatically adjust the cooling capacity of the unit by controlling the compressor capacity adjustment slide valve, making the operation more energy-saving and efficient.

8. Automatically record the first 20 fault alarm points to facilitate maintenance personnel to judge and repair the unit in time.

9. Low noise, small vibration, designed according to industrial standards, suitable for 24-hour operation throughout the year.
