NH3 Compressor Protection

Technical data: HBCP

HBCP is a variant of the HBX vapor quality sensor used at the compressor inlet. HBCP can provide an alarm, when the liquid content in the gas exceeds the critical set point or simply provides an analog signal to a PLC. The sensor can prevent liquid refrigerant from entering the compressor, causing damage to the moving parts. The sensor has a high sensitivity and detects even small liquid droplets before they become critical to the compressor. The sensor has a uniquely short reaction time which can be used for emergency stop of the compressor, but typically the signal can be used as an early warning or as a part of the evaporator control.


Product features

The sensor protects the compressor against damage in the event of liquid hammer from the system.
Setting up the sensor using a PC allows for adjustments to match the system and the compressor.
Instantaneous reaction without delays.
