Honeywell Analytics S301-IRF-R22 Refrigerant Gas Sensor R22

The Honeywell Analytics S301-IRF-R22 is a refrigerant gas sensor designed to detect leaks of R22 refrigerant in HVAC equipment. It looks for R22 molecules in the air on a constant basis using infrared absorption spectroscopy. The sensor notifies the building automation system of a leak by sending an alarm signal, which notifies maintenance staff of the problem. By acting quickly, possible safety risks, environmental harm, and expensive refrigerant loss can all be avoided.The S301-IRF-R22 is commonly installed in mechanical rooms, chiller rooms, and other spaces that house HVAC equipment that uses R22 refrigerant. It is a robust, low-profile sensor that may be installed low on a neighboring wall or directly on a chiller pad.Replacing R22 refrigerant can be costly as it is a controlled material.
