Floodline RGD1301 Refrigerant Gas Sensor

The Floodline RGD1301 Refrigerant Gas Sensor can be used as a stand-alone refrigerant alarm system OR be included as part of a larger water/oil leak detection system. It can also be used to provide a dedicated refrigerant gas detection alarm package.

The Floodline RGD1301 ensures companies comply with BS EN378 and detects refrigerant gases to HSE Occupational Exposure Limits.

BS EN378 specifies the installation of fixed refrigerant leak detectors in both existing and new systems of all sizes (with certain exceptions).

The Floodline RGD1301 sensors can be connected to a standard Floodline Control Panel giving additional audible and visual alarm features in addition to the facility for onward communication to BMS etc.
