Cascade leakage detection in liquid ammonia

Technical data: HBAC-U

This sensor must be installed in the liquid ammonia circuit. It is the most efficient sensor for detecting a leakage and it detects even very small leaks rapidly.

HBAC-U is used for detecting leakage in cascade systems. The sensor triggers an alarm if there is an CO2 leak in the NH3 part. A leak results in several hours of cleaning the pipes and heat exchanger. If a CO2 leak occurs in the NH3 part, salt crystals are formed. These salt crystals are very corrosive and lead to clogging of the parts. If the leak is not stopped in time, it can lead to extensive damage to the heat exchanger, pipes, and pump.

Oil level and leakage detection
If the sensor is installed in the oil collector in a shell and plate or shell and tube vessel you can use the sensor for both detecting oil and leakage by using the mA signal. This requires a special setting, but all versions can be modified for this.
