HBCP: compressor protection by HB Products

Danish supplier HB Products has brought to market a sensor capable of detecting liquid overflow from the liquid separator. HB Products' experience shows that the costs associated with compressor damage can vary from 10 000 to 60 000 Euros, depending on the extent of the liquid overflow from the liquid separator, as well as on the make of the compressor. Apart from the servicing costs, additional costs can easily add up for the days when the refrigeration system is out of order. It is this proble

Depending on the flow conditions, the HBCP sensor can be mounted either upstream or downstream. It comes in two different sizes: ¾” and 1” with NPT & BSPP thread The ¾” version is used in pipes whose dimensions are smaller than 2” and the 1” version is used in pipes whose dimensions are bigger than to 2".

HBCP prevents compressor damage

The sensor ensures that liquid refrigerant does not enter the compressor causing damage to the moving parts. The sensor has a high sensitivity and detects even small liquid droplets before they become critical for the compressor.

The sensor has a unique low reaction time, ensuring that the compressor is not damaged. In the event of liquid hammer, an instantaneous alarm is sent to the compressor control, which then signals an emergency stop to the compressor. The sensor measures the total gas and liquid capacity, which can be read in puff (pF).

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.

HBCP additional features

  • Simple PC tool set up allows adjustments to match the system and the compressor
  • Built-in data logger works as the compressor’s black box
  • Early warning and alarm in case of liquid hammer
  • Plug and play solution which requires no extra accessories
