4. The unit can be controlled by single chip or PLC to meet different needs of customers;

5, the unit can provide R134a, R22 and other refrigerants according to customer needs.

Air-cooled screw full liquid unit selection recommendation

First, 40STE-AS3 type air-cooled screw flooded unit

It adopts single-loop design and is divided into three sections or four sections of energy adjustment, which is suitable for all kinds of refrigeration places.

Second, 40STE-AD3 type air-cooled screw flooded unit

It adopts double-loop design and is divided into six or eight-stage energy adjustment, which is suitable for large and medium-sized refrigeration places.

Third, 40STE-AHS3 type air-cooled screw flooded unit

Air-cooled heat pump unit is designed with single circuit In addition to the function of the chiller, it can also provide heating in winter, easy to operate, convenient and environmentally friendly.

Fourth, 40STE-AHD3 type air-cooled screw flooded unit

Double-circuit design of air-cooled heat pump unit, summer cooling, winter heating, two compressors are spare for each other, easy to operate. It has high operating efficiency, safety and reliability, and is suitable for large-scale applicable places where single unit operation and multiple units are combined.

Installation and maintenance

1. It can be installed in the roof of the building or other well-ventilated environment without additional cooling water system;

2. It is recommended to use multiple units in parallel during transportation, lifting and installation;

3. The unit should be kept dry and ventilated, and the surrounding air should not contain corrosive substances, so as to avoid close proximity to chimneys, generators, boilers, etc. where acid gas or heat is easily generated;

4. In order to prevent the bottom of the unit from rusting, it is better to use the cross steel frame to support the bottom of the unit during installation, so that the unit is not less than 20cm away from the ground;

5. The inlet and outlet of the cold (hot) water pipe and the front and rear nozzles of the cold (hot) water pump need to be equipped with shockproof soft joints. Gate valve thermometer, water pressure gauge, heat exchanger outlet pipe side water flow switch, water pump inlet side filter and other auxiliary devices;

6. When configuring the power cord, please select a wire with a large cross-sectional area, so that the power flow of the power cord is not less than 20%.
