How to use and install the water cooled chiller?
1. If customer side is a closed loop water circulation, need to use buffer water tank, becuase this chiller evaporator is shell and tube, it's a closed loop.
2. If customer side is a open type loop, can connect the chiller directly.
3. Condenser connect with the cooling pump, and cooling tower, to make the cooling for own chiller.
4. The evaporator connect with the chilled water pump, to supply the cold water to user.
1. Industrial Air cooled scroll water chiller for plastic injection, molding , PVC line machine
2. Air cooled water chiller, larger cooling capacity , screw type chiller.
3.Water cooled scroll compressor chiller.
4. Water cooled screw chiller, single compressor chiller, and two compressor chiller.
