HGM-MZ, 12 Zones, 120-240 VAC / 50/60Hz Input Power

Bacharach’s Multi-Zone Gas Monitor delivers the best refrigerant leak detection available, with industry-leading MDL of 1ppm for halogenated gases, the fastest sampling frequency and the widest range of refrigerants accurately detected. The large graphic LCD display and LED status indicators provide a system-wide overview at a glance.

The Multi-Zone enhances effective refrigerant management and ensures compliance with refrigeration safety standards (ASHRAE 15, EN 378, CSA-B52) and emissions regulations (F-Gas, CARB RMP). It detects leaks early to enable cost savings by reducing refrigerant recharge, enhancing energy efficiency and reducing risk of refrigeration failure and produce loss. A variety of communication interfaces are available including Modbus, BACnet and LonWorks, allowing easy integration into BMS / BAS systems and remote monitoring solutions.

• Proprietary infrared (NDIR) sensor accurately detects the presence of a target gas down to an industry-leading 1 ppm Minimum Detection Level (MDL)
• Sensor is not prone to false alarms caused by cross-interference from other gases or sudden changes in temperature or humidity
• Gas library contains 60+ refrigerants, including CFCs, HFCs, HCFCs, HFOs and natural refrigerants (R-744, R-717)
• Backlit display shows real-time concentration readings and makes configuration and self-diagnostics intuitive
• Capable of monitoring up-to 12 zones (expandable up to 36 sample points) and detecting multiple gases with a single monitor
• Two optional analog outputs (4-20mA) and Modbus communications (slave) for integration with third-party BMS / BAS control systems
• Three user-configurable relays (leak, spill and evacuate) may be used to activate external beacons / sounders, ventilation or other countermeasures
