Service costs kept down with HBCP compressor protection…

At a large food manufacturer in Germany the system’s service costs were so great due to the age of the system that it was time for it to be replaced . At the same time, the old system was based on Freon 22 and it was therefore a requirement to replace the system within a number of years. 

compressor protection

In the transition phase, where the Freon 22 system had to be kept running, 4 HBCP compressor protection sensors from HB Products were installed. This was carried out since the customer had experienced particularly high service costs for the compressors. There were numerous faults found with the expansion valves which in turn had often caused liquid to return back to the compressor.

The costs of buying and installing the compressor protection sensors were limited and could easily be covered by the savings from lower compressor service costs.The refit time was similarly limited, and the customer did not hesitate long before approving the installation of the compressor protection sensors.

Fact box:
Liquid overflow is the system owner’s biggest nightmare!

The costs associated with compressor damage can vary between 10,000 and 60,000 Euro, depending on the extent of the liquid overflow from the evaporator or liquid separator as well as the make of the compressor. Liquid overflow is the system owner’s biggest nightmare! Once a liquid overflow begins, so does the discussion with the system manufacture and/or the compressor manufacture on the apportionment of liability. Apart from servicing costs, additional costs can easily add up for the days when refrigeration system is out of order.

Technical data:
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 found on refrigeration compressors. The sensors can thereby ensures that liquid refrigerant does not enter the compressor, causing damage to the moving parts.

The sensor has a high sensitivity and even detects small liquid droplets before they become critical to the compressor. The sensor has a uniquely low reaction time, and thereby ensures that the compressor is not damaged. In the event of liquid hammer, an instantaneous alarm is sent to the compressor control, which must signal an emergency stop to the compressor. The sensor measures the total gas and liquid capacity, which is displayed 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.
