Product Description

1)The Feature of 485kw 480v/60hz R134a air cooled screw chiller
a..Excellent performance
The main body is equipped with globally advanced semi-hermetic screw compressor,intergrating the motor,without worrying about shaft seal leakage.
The single or number of compressors are provided with startup-shutdown cycle control program so as to uniformly load parts and extend their service life.
Multiple refrigrating cicuits are provided for the sigle or number of comprssors ,and when on cicuits is under maintenance,other cirucits are albe to run nomally as mutual standby.
Unload deprssurized start is provided for the compressors to prevent the impact on the power grid

b.Complete safety protections
Pressure protection:High and low-pressure protecting devices
Motor protection:Voltage-loss protection, phase-loss protection,inverse phase protection and over-heat protection.
Anti-freezing protiction:The unit will stop running in case of excessively low cooling water temperature
Safety valve protection:when the refrigerant pressure exceeds a certain value, the safety valve will be turned on automatically
Above device  protections ensure the safe and reliable running of the unit
c.Easy assembly 
The unit enjoys compact structure,covers small area,saves machine room space;it almost not vibrates due to the provision of foundation anti-vibrating measure.
Upon delivery of the units R22 refrigerant and lubricationg oil have been filed into it, then it's only necessary to connect the evaporator water pipe during assembliy,saving time and cost.
