Design features

Well Known Brand Compressor

¨      Unit adopts Germany BITZER or Taiwan HANBELL brand semi-hermetic screw compressor. The latest 5 to 6 patented screw rotor profile with excellent efficiency.
¨      Adjustable infinite or closely stepped capacity control, features energy efficient, stable and quiet running.
¨      Most advanced patented highest precision manufacturing process.
¨      Built-in full intelligent monitoring and protection including thermal motor temperature
monitoring, phase sequence monitoring, manual reset lock-out, oil temperature sensor.
¨      Wide range of refrigerant for option, including R134a, R407c and R22(R404a, R507c upon request).

Microprogramming Control System

¨      Industrial PLC centralized control combined with compressor capacity control system, precisely monitor.
¨      Integrated protection for low temperature, high/low pressure, anti-freezing, phase missing, anti-phase, overload, motor over temperature, oil differential, flow switch, start up latency.
¨      Optional operation language, menu leading, unit running state easy to adjust.
Easy Installation, Reliable Running
¨      Closely stepped start-up, minimize impact to electricity.
¨      Steady and safe running, low vibration, easy for installation.
¨      Compact structure, less space demand and light in weight, easy for transport and installation.
¨      Completely wired, inspected and tested pre-delivery, saving installation time and cost.
