Design features:
Coolant temperature range from 5º C to -40º C.
High
efficient semi-hermetic twin-screw compressor adopted, high COP, steady
performance and long service life.
Compressor stepped capacity control,
minimize starting current and impact to grid.
25%-100% continuous capacity
control, ensuring compressor full performance, saving running cost for
customers.
High accuracy touch screen and imported PLC controller
adopted.
Multi-protection function: Compressor discharge over temperature,
motor over temperature, anti-freezing, over current, phase sequence, high/low
pressure, flow switch.
Mass Storage PLC, allows permanent reservation of more
than 100 fault records, precisely monitors unit running state.
Pass word
setting, avoids unit from shut down or damaged by accidental factor.
Control
components including thermal expansion valve, solenoid valve, check valve are
supplied by international brand, ensuring steady and efficient running under
wide range of working condition.
Units are completely tested and operated at
full load, leave factory with refrigerant, can be start once water and power is
connected.
Compressor with built-in exhaust pot silencer ensures low noise
running.
Corrosion-resistance water system upon request.
Refrigerant
option: R22, R407C, R404A, R134A and R410A.
