CAMGas Permanent High-precision Refrigerant Gas Detectors

According to European regulation EN 378-3

The location of the detectors should be chosen depending on the refrigerant. Refrigerant detectors will be designed to quickly notify either a dangerous concentration of refrigerant in the surroundings of a refrigeration
system or contamination of the environment. The premises or areas where they should be located are defined in the following sections.

In each specific machine room the concentration of refrigerant should be controlled by a system with at least one sensor that activates an alarm located in premises occupied by people and that eventually isolates parts
of the refrigeration system.

In cold storage rooms and refrigerated premises for processes in which in the event of refrigerant leaks the practical acceptable limits of refrigerant concentration may be exceeded, a leak detection system will be installed that activates an alarm and isolates part of the refrigeration system.

Permanent high-precision gas detector with an optical and acoustic alarm That is compulsory to install in compressor rooms and cold room stores. Furthermore, the use of this device allows immediately detecting possible gas leaks with levels of 250 ppm (according to model) to minimize risks for people in occupied spaces and economic impact of the loss of refrigerated gas.
