The physical environment of data centres and computer rooms has to be rigorously controlled. This is, of course, achieved by air conditioning. Depending on the size of the area, there may be multiple systems, most of which are typically charged with some form of refrigerant HCFC or HFC gas, such as R410A, R134A, R407C. Should there be a failure of any part of the system, there is a risk of refrigerant gas leaking into the atmosphere. Leaking systems are inefficient and more expensive to operate but also pose a health risk to occupants as refrigerant gas depletes oxygen and can in some cases cause suffocation.

Installing a fixed point refrigerant gas leak detection system will monitor for potential leaks continuously and can give audible/visual alarm as well as the ability to connect to a BMS if available.

Sensors are positioned close to primary sources of potential leaks e.g. near fan coil units, pipework joints, compressor compartments of chillers or the base of pipework risers.

Sensors can be stand-alone or multiple sensors can be linked to master panels for central monitoring.
