Water Cooled Chiller Shell And Tube Evaporator Reciprocating Compressor
Screw chiller with high efficiency, good performance, low noise, vibration, energy saving, high reliability,
long life and other advantages.
According to customer needs and the size of cold tonnage, using single or multi-machine combination.
Compressor can change according to the load, automatically turn alternately, balance the number of
operating hours of the compressor, greatly extending the use of chillers.
The use of industrial
1. injection molding machine for the choice of the size of the machine for injection
molding machine mold cooling, that is, need to use 25HP chiller. For the cooling of other equipment,
depending on the specific flow rate of the cooling water cycle.
2. Chiller water tank and pump selection Sometimes according to the actual situation of the customer
factory, open chiller, in the external pump, the pump power requirements and the same type of box chiller
requirements the same.
3. Chiller back to the water temperature, preferably not higher than 40 degrees, the higher the return
water temperature, the greater the damage to the compressor.
