CSW Series Water Cooled Screw Water Chiller
COOLSOON screw type chiller adopt the international famous branded screw type compressor , and equip with the high efficient copper as condenser , evaporator and famous branded control components, which make the chiller unit feather as compact size, low noise and vibration , high cooling capacity, easy operate and long service life.
Compressor features:
*The new type international brand high efficiency screw type compressor, which is 20%-30% high efficient than normal compressor.
*The cooling capacity control take the four steps (100%-75%-50%-25% )or three steps (100%-66%-33%)or no steps control system.
*High efficiency, low noise and vibration, the unit no need any anti -vibration measures and easy to install.
*It can take the other environmental protection refrigerant R134A, R407C, R410A except the R22.
The Control Panel System
*The German brand SIEMENS PLC program control system , human-computer interface with big LED touch screen , can make the dialogue between man and machine. Multi-language display the working condition of the machine, and self-diagnosis function can detect the machine fault automatically, which is convenient for the worker to operate and supervise the machine.
* It can connect the external industrial interface ,which is convenient to acheive the computer monitor by intelligent network control.
Safety Protection Function
*High and Low pressure , compressor overheating , overloading, over temperature , flow switch, phase sequence, phase-missing, exhaust overheating, anti-freezing and multiple safety protection to guarantee the machine in a safe and stable operation.
It should equip with the big cooling tower to keep a good ventilation of chiller unit.
