MVR-300 VRF Refrigerant Gas Detector
The MVR-300 is a fixed refrigerant gas detector designed for continuous monitoring in occupied spaces using VRF/VRV air-conditioning systems. It provides audible and visual alarms and communicates with building automation systems to warn of refrigerant leaks that may pose safety risks to occupants.
Features
Continuous monitoring for VRF/VRV refrigerants in occupied indoor areas
Audible and visual alarms for immediate leak notification
Two relays for alarm and fault signalling
Modbus RTU communication for integration with building systems
Replaceable refrigerant-specific sensors
Self-diagnostics and easy field calibration
Low-profile flush-mount design for standard electrical boxes
