New sensor - Compressor Protection

HBCP is a new revolutionary, patent-pending sensor technology and it is the first sensor in the world capable of measuring the condition of gas and liquid refrigerant in a refrigeration system.

HBCP is used for detecting gas quality at the intake of refrigeration compressors. The sensor thereby ensures that liquid refrigerant does not enter the compressor and causes damage to the moving parts. The sensor has a high sensitivity and even detects small liquid droplets before they become critical for the compressor.

The sensor has a uniquely low reaction time, thereby ensuring that the compressor is not damaged. In the event of liquid hammer, an instantaneous alarm is sent to the compressor control, which must 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 logs. All alarms are saved, so the sensor also functions as a “black box”. The data log can be read by connecting a PC. Similarly, the sensor can be set up using a PC.   

The product’s 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.
  • The sensor has built-in data logs that work as the compressor’s “black box”.
  • Instantaneous reaction without delays.

HBCP is designed for installation in systems using NH3 & HFC refrigerants. Depending on the flow conditions, the sensor is mounted either upstream or downstream. It comes in two different sizes, ¾” and 1”, where ¾” is used in pipe dimensions <2” and the 1” version is used in pipe dimensions >2".

Built-in data logger
Apart from functioning as an alarm, the sensor has a built-in data logger. The data logger can save up to 16,000 figures, with programmable time intervals.
