MiniCal III CS

The MiniCal III CS system was specially developed for leak detection of synthetic refrigerants (HFC/CFC). Many years of experience have resulted in a practical system that is suitable for use in water circuits. The compact design allows installation directly in the secondary circuit.

The installation of the robust MiniCal III CS fitting is quick and uncomplicated. A butterfly valve is installed on a pipe socket with DIN flange according to the installation instructions and enables subsequent service and maintenance work during operation.

A gas-permeable membrane separates the water circuit from the measuring chamber and is adapted to the prevailing operating pressure (max. 3 bar). HFCs / CFCs are inert gas mixtures that do not mix with liquids. The detection of HFCs / CFCs, such as R12, R22, R134a, R402a, R404a, R407c, R406a, R507, is done with selective gas sensors that can also detect low gas concentrations (depending on the type of gas and sensor).

Appropriate safety actions can be initiated at an early stage, thus preventing hazards to people, the environment and plant components. The integrated gas sensor supplies a 0.2 to 1 or 4 to 20 mA signal for the alarm, which can be connected to an evaluation unit or directly to a PLC.
