screw chiller,water chiller
Cooling and heating
Screw compressor
Compact physical footprint
Cooling capacity:150~1900Kw
HWAL series Air cooled screw water chiller
Feature:
Excellent performance
The main body is equipped with globally advanced semi-hermetic screw compressor,
integrating the motor, without worrying about shaft seal leakage.
The single or a number of compressors are provided with startup-shutdown cycle control program
so as to uniformly load parts and extend their service life.
Multiple refrigerating circuits are provided for the single or a number of compressors, and
when one circuit is under maintenance, other circuits are able to run normally as mutual standby.
Unload and step-down voltage start is used by the compressor to prevent the impact on the power grid.
Ultra-low noise turbine blade design.
V-shaped appearance provides better heat dissipation.
Exclusive high-temperature unit
The high-temperature unit is able to provide 55-56°C hot water for air conditioning system,
and the heat recovery type provides water for living, which conform to the
Head-Power's high requirement on energy saving.
Easy installation
The unit enjoys compact structure, covers small area, save machine room space; is almost not vibrates
due to the provision of foundation and vibrating measure.
Upon delivery of the unit, the refrigerant and lubricating oil have been filled into in, then it's only necessary
to connect the evaporator water pipe during installation, saving time and cost.
Lower running and maintenance cost
Intelligent program control can be achieved for the unit according to the load demand: 100%, 75%, 50%,
25%(or start), 0 and stepless energy adjustment, reducing energy consumption.
Total parts number of screw compressor is only 1/10 that of the reciprocating compressor, enabling the
unit to have simple structure and less venerable parts, without the use of are intake and exhaust valves,
not sensible to wet stroke and extremely low fault rate.
Failure-free operation time of the screw compressor is up to 40,000 hours.
Complete safety protection
Pressure protection,Motor protection: Anti-freezing protection: Safety valve protection:
Above device protections ensure the safe and reliable running of the unit.
