Cold storage refrigerant gas alarm - SKA/NE-301 (R134a)
Freon gas alarm
Freon alarms are used to detect leaks of refrigerants such as R22, R134a, R410A, R507; most Freon gases are heavier than air, settle on the ground after leakage, high concentrations can causeAsphyxiation risk, some refrigerants (R32, R290) are also flammable China Building Science... The entire system consists ofDetector (probe) + alarm controllerComposition, can provide audible and visual alarms, link exhaust fans, shut down refrigeration units, and upload alarm signals to the duty room.
