3.The unit has reliable safety protection devices, including high and low voltage protector, exhaust overheating protector, compressor motor overheating protector, overload current protector, antifreeze temperature protector, water flow protector, emergency stop switch, temperature sensing fusible plug, safety valve, etc.

Products Description

1.Screw machine chiller characteristics

(1) The water-cooled screw machine is generally an open upper and lower structure of the chiller. Simple structure, less moving parts, convenient installation and debugging, reliable operation, low cost;

(2) the single machine has large cooling capacity and high volumetric efficiency;

(3) the cooling capacity can be stepless adjustment.

2.Control system

The controller of  screw chiller, all electrical parts adopt Schneider brand. Electric control box waterproof design.

Independent and precise control system makes the system run stably and accurately.

3.Water system

The pump connected to the user tank on the chilled water side of the evaporator is the chilled water pump. The condenser side needs to be connected to the cooling water side, and the cooling pump and cooling tower need to be equipped to take away the heat of the condenser in the working system of the chiller, so as to achieve the function of refrigeration.

APPLICATION FIELD

Screw chiller is suitable for plastic, electronic manufacturing, electroplating, pharmaceutical and chemical industry, ultrasonic cooling, printing and other industrial production. It can accurately control the temperature required by modern industrial mechanized production, so as to greatly improve the production efficiency and product quality.
