    Bacharach’s MGS-450 Refrigerant Leak Detector is designed for equipment rooms, freezers and cold rooms where refrigerants, toxic and combustible gases may be present.

    The MGS-450 Refrigerant Leak Detector can be used as a standalone leak detection system, connected to the MGS-408 and MGS-402 Gas Detection Controllers or integrated with local BMS / BAS via Modbus RTU.

    The MGS-450 offers a variety of pre-calibrated sensor modules that do not require calibration gas. The plug-and-play sensor modules can be quickly and easily exchanged, and no training is needed.

    The refrigerant gas detector’s status can be viewed in real-time on the MGS-400 mobile app via Bluetooth. The MSG 450 can be commissioned, configured and maintained on the mobile phone app with ease and without special training or tools.

    The sensors can set off the integrated audible and visual alarm to alert personnel of a refrigeration leak.

    In addition, the MGS-450 Leak Detector includes an analog output and three output relays (fault, low alarm, high alarm) for local alarming, auxiliary ventilation, or refrigerant flow restriction.
