Typical applications

The GSH-HFC(R134a) sensor is intended for monitoring R134a refrigerant leaks in environments such as plant rooms, air-conditioning and refrigeration equipment, refrigerant storage areas, or other installations where refrigerant concentrations need to be monitored. The device provides early leak detection, helping to minimise the risks associated with refrigerant leakage and protect both the environment and the equipment.

1,1,1,2-Tetrafluoroethane (R134a)

R134a is a synthetic refrigerant widely used in refrigeration and air-conditioning systems. It is a colourless gas with a faint odour and low toxicity. Although it is non-flammable, its release may impair air quality or contribute to greenhouse gas emissions. Monitoring R134a leaks is essential for maintaining equipment safety and complying with environmental standards.

Easy installation

The smart sensor offers a major advantage during calibration – the entire process can be carried out separately from the installed detector. While the E2639-GSH main unit remains in operation at the installation site, the GSH sensor module can be removed and calibrated independently – at the distributor’s premises, the integrator’s facility, or directly at the manufacturer Evikon MCI. This is done using the dedicated SSC configurator, through which the module is connected to a computer. Once calibrated, the GSH module simply slides back into place via the M12 connector – with no need to open the device housing, no complicated procedures, and no downtime for the entire installation.
