• 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

The MSA Bacharach Multi-Zone delivers the best refrigerant monitoring available, with industry-leading MDL of 1 ppm 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, detecting 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.

■ 1 ppm Minimum: Detectable Level Detects leaks that other instruments can't
■ Early detection of refrigerant leaks: Mitigate refrigerant loss, protect produce, enhance energy efficiency
■ Monitors up to 16 remote areas, expandable to 48 monitoring points: Ideal solution for grocery store refrigerant monitoring
■ Over 50 different refrigerants accurately detected: Monitor multiple refrigerant circuits with a single detection system
■ Infrared sensor technology: Accurate, precise measurement unaffected by other gases, temperature or humidity
■ High performance sampling pump: Industry-leading cycle times for monitoring all zones with greater frequency
■ Minimal maintenance and no calibration required: Low cost of ownership
■ Halogen, CO2 and NH3 versions available: Suitable for a variety of refrigerant monitoring applications
