Honeywell Refrigerant Gas Monitors

A building’s mechanical room is the central hub of its heating, ventilation and air conditioning (HVAC) system. This includes, but is not limited to, central utility plants, boiler and chiller rooms, mechanical and electrical rooms, fuel rooms, as well as metering and communications closets. The chillers, boilers and combustion equipment in these rooms can potentially leak harmful combustible or toxic gases, including costly refrigerant gases such as R11, R22 and R123. Current building codes provide very specific gas monitoring system installation requirements in order to safeguard against refrigerant leaks. Honeywell Refrigerant Gas Monitors give you the security you need, protecting you from dangerous gas leaks.
