Safety protection device
The following safety devices are equipped as standard.
High pressure protection(High pressure switch & high pressure sensor)
Low pressure protection(Low pressure switch & low pressure sensor)
Compressor thermal protection
High discharge temperature on the compressor
Phase monitor; Star/Delta transition failed
Low-pressure ratio; Low oil level protection
Interrupter protection; Overload compressor protection
Over-voltage & low- voltage protection
Sensor malfunction protection
Contactor malfunction protection
Freeze protection
Note:
Nominal cooling capacities are based on following conditions: Chilled water inlet/outlet temperature 12/7℃(53.6F/44.6F);
Cooling water inlet/outlet temperature 30/35℃(86F/96F).
The design fouling factor for both evaporator and condenser are 0.086m2•℃/kW (0.0005ft2 F.hr/Btu).
