Excellent performance
The main unit is equipped with semi-hermetic screw compressor, integrating the motor, without worrying about shaft seal leakage.
The single or more compressors are provided with startup-shutdown cycle control program so as to uniformly load parts and extend service life. Multiple refrigerating circuits are provided for the unit, and when one circuit is under maintenance, other circuits are able to run normally as mutual standby. Unload and step down voltage start is provided for the compressors 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 55-60ºC hot water for air conditioning system, and the heat recovery type provides water for living, which conform to the Head-Power's high requirements on energy saving.
Easy installation
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 unit, the refrigerant and lubricating oil have been filled into it, 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 air 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 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 protection: The unit will stop running in case of excessively low chilled water temperature
.
Above device protections ensure the safe and reliable running of the unit.
