Refrigerant Gas Leak Detection
Sensors are installed in compressor rooms within close proximity to compressors, close to the floor. Use series 60XX sensors and Opera 6000 control unit that is installed outside of the mechanical room at eye level to signal a potential risk to someone entering the room. Controller features a built in audible alarm and strobe.
When using nitrogen in cryogenic applications the gas displaces air and oxygen (normally 21.5 percent) resulting in asphyxiation risk.
