Strainer Housing - Compressor Protection

Technical data:: HBCP-ST

HBCP is a simplified 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. This alarm and a measured value are typically sent to a PLC. This information can be used for controlling the system and stop the compressor to avoid liquid slugging.

The sensor can prevent liquid refrigerant from entering the compressor and causing damage and break down. Especially in larger systems with several evaporators it can be difficult to control all unit and this sensor can be used for both surveillance and trouble shooting.

The HBCP and the vapor quality sensor measures the amount of liquid in the gas passing through the sensor and react instantly.

The sensor is available in two versions:

• Rod style sensor which must be installed in an elbow after at the end of a horizontal pipe. The sensor must be located at the bottom of the pipe where the liquid flows. The sensor will not work if located at the middle of the pipe or in a vertical pipe.
• The strainer house sensor is installed in an empty strainer house, and it measures all the liquid flowing on the walls.

The strainer house solution is available from DN20 to DN300 in a carbon steel version and from DN20 to DN65 in a stainless steel version.
