Revolutionary new sensor for compressor protection

November 2013

The new HBCP sensor from Danish manufacturer HB Products uses revolutionary, patent-pending technology, and is the first sensor in the world capable of measuring the condition of gas and liquid refrigerant in a refrigeration system. Designed to detect gas quality in the intake of refrigeration compressors, the sensor ensures that liquid refrigerant does not enter the compressor to damage the moving parts. The sensor has a high sensitivity and fast response, and even detects small liquid droplets before they become critical for the compressor.

In the event of liquid hammer, an instantaneous alarm is sent to the compressor control, which can then signal an emergency stop to the compressor. The sensor measures the total gas and liquid capacity, which can be read in pF.

The sensor has built-in data logging. All alarms are saved, so the HBCP also functions as a “black box”. The data log can record up to 16,000 readings with programmable time intervals, and can be read and set up using a PC.

Key features are:

  • The sensor protects the compressor against damage in the event of liquid hammer within the system.
  • Setting up the sensor using a PC allows for adjustments to match the system and the compressor.
  • The sensor has built-in data logs that work as the compressor’s “black box”.
  • Instantaneous reaction without delays.

The HBCP is designed for installation in systems using NH3 & HFC refrigerants and is available in two different sizes, ¾” for pipe sizes less than 2” and the 1” for larger pipe sizes.

HB Products are available in the UK and Ireland from Thermofrost Cryo Plc.
