Description

6203-0011 MVR-300 Variable Refrigerant Flow Gas Detector, 100-240VAC, Low and High Alarm, Modbus, LED and 80dB Alarm - R-407c, 0 to 2500 ppm by Bacharach

The MVR-300 detector is specifically designed to provide continuous monitoring for refrigerants associated with high-efficiency, high volume refrigerant cooling and heating systems, such as VRF/VRV (Variable Refrigerant Flow/Variable Refrigerant Volume) sytems. Typical applications include hotels, dormitories, hospitals, office 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 rescue teams.

The on-board Modbus RTU interface provides real-time information about refrigerant concentrations, status and settings. It also enables custom configuration of the MVR-300 to any application specific requirements using multiple Modbus registers. The MVR-300 is designed for easy installation and simple maintenance.

The MVR-300 is compatible with MVR-SC Controller.
