RM & RM-V

Gas Detectors for Occupied Spaces

Refrigerant detection in occupied spaces is most typically deployed using semiconductor sensors. Semiconductor, metal oxide sensors are a long-proven method for detection of HFC and HFO refrigerants and blends. They have a number of benefits.

Semiconductor sensors can be cross-sensitive to other reducing gases and consideration should be given to this when selecting an installation location. For example, the location should be away from vanity units, mirrors, and bathrooms where aerosol products and high levels of steam may be present.

Due to the aesthetic nature of a domestically occupied space, the presence of a typical gas detector is often unacceptable. This can be overcome by using a detector that is recessed into the wall, with an unobtrusive faceplate being the only visible part.

The RM and RM-V detect leaks of refrigerant gas in occupied spaces, typically from HVAC systems including VRF/VRV air conditioning systems. Applications include hotel rooms, offices, care homes, prisons, and other occupied facilities.

BENEFITS

This technology has a number of benefits:

•Cost effective   

•Fairly long lifetime (~5 years) 

•Low maintenance costs

RM & RM-V is calibrated for R401A as standard. Responds to other HFC gases. Alternate calibrations possible on request.

The following options are available as standard:
