Gas Alarm Systems can design, engineer, supply, service and maintain Refrigerant Leak Detector Transmitter  &  Control Alarm System to meet the safety standard guidelines of Refrigerants and Food Industries.

We have Refrigerant Gas Detector in our product range which is highly accurate & fast responsive at the low-cost price having a long life benefit.

As we know that Refrigerants gas are heavier than air. They tend to remain stagnant and progressively replace oxygen. For optimal efficiency of your refrigerant leak detection system, refrigerant sensors should be placed under the cooling unit and linked to a gas detection display control unit. In case of leakage, the controller unit will shut down the power supply of the cooling installation.

PolyGard®2 sensors are used for leakage detection in refrigeration systems. Refrigerants are highly toxic and usually very harmful to the environment. An undesired leakage of the refrigerant has to be strictly avoided. The gas alarm systems of MSR-Electronic reliably detect any gas leaks.

First and foremost you protect human life and the refrigeration system is monitored.

All products comply with and even exceed the new European standard EN 378.
