Bacharach HGM-MZ Halogen 16 Zone Refrigerant Monitor

SKU: 3015-5046

Multi-Zone Gas Monitor

Industry Leading Precision Monitoring for Low-level Gas Leak Detection.

Bacharach’s Multi-Zone Gas Monitor provides precise measurements enabling early leak detection for compliance with refrigeration safety codes (ASHRAE 15, EN 378, CSA-B52) and emissions reduction standards (F-Gas, CARB).

  • 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 16 zones (expandable up to 48 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

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.
