Bacharach MVR-300 Specifications
REFRIGERANT SAFETY COMPLIANCE
MVR-300™ VRF Refrigerant Leak Detector
For VRF Systems in Occupied Spaces
DESCRIPTION
The MVR-300 gas detector is specically designed to provide continuous monitoring
for refrigerants associated with high-eciency, high volume refrigerant cooling and
heating systems, such as VRF / VRV (Variable Refrigerant Flow / Variable Refrigerant
Volume) sytems. Typical applications include hotels, dormitories, hospitals, oce
buildings and apartment buildings.
The MVR-300 audible and visual alarms alert occupants and simultaneously
communicate to Building Management Systems / Building Automation Systems
(BMS / BAS). Two on-board relays can be used to close valves, activate alarm devices
and exhaust fans or initiate emergency calls to building management.
The on-board Modbus RTU interface provides real-time information about
refrigerant concentrations, status and settings. It also enables custom conguration
of the MVR-300 to any application specic requirements using multiple Modbus
registers. The MVR-300 is designed for easy installation and simple maintenance.
The MVR-300 is compatible with the Bacharach MVR-SC Controller.

Important Note: Large refrigerant leaks into occupied spaces can reach concentrations that pose a suocation
risk to the occupants. The MVR-300 is not designed to be used as the sole safety device for this risk. Safety of the
occupants also must take a system designed approach that includes things such as ventilation, detection, early
warning, mitigation and design redundancy.
