Additional information

With the possibility of monitoring up to 16 zones simultaneously (48 sampling points), and a detection threshold of 1 ppm, the HGM-MZ freon controller unit is currently the best equipment on the market for monitoring refrigerant gas leaks on site.

The Bacharach HGM-MZ controller is equipped with an NDIR infrared sensor with a very low detection threshold (1 ppm) which makes it possible to identify, by aspiration up to 365m away, the smallest refrigerant gas leaks. The controller can be adapted to many sites using refrigerant freon gas (data centers, cold storages, machine rooms, refrigerated areas in stores, etc.), and allows complete control of refrigerant leaks resulting in reduced maintenance costs (including renewal of the refrigerant gas). At the same time, the installation of an HGM-MZ controller makes it possible to satisfy the requirements for bringing these sites into compliance with regard to the legislation concerning the use of freon gas.
