Multi-Zone Gas Leak Monitor

Multi-Zone

 
 

 
 
Multi-Zone Gas Leak Monitor
  • Monitors up to 16 remote areas, expandable to 48 points
  • Proprietary Infrared (NDIR) sensing technology
  • Low detection limits (as low as 1 ppm)
  • Long sampling distances (up to 1,200 ft / 365 m)
  • On-board visual/audible alarms, 4 relay contacts mitigates refrigerant loss

 

Bacharach’s Multi-Zone Gas Leak Monitors offer superior performance, flexibility and functionality for low level continuous monitoring of refrigerant gases used in most commercial systems including: Chlorofluorocarbons (CFC), Hydrochlorofluorocarbons (HCFC), Hydrofluorocarbons (HFC), Ammonia (NH3) and Carbon Dioxide (CO2). An infrared (NDIR) sensor enables the Multi-Zone to accurately measure to the lowest parts per million (ppm) levels. The Multi-Zone is affordably customized for any application with a built-in library of 50 gases and a scalable platform allowing up to 48 points of remote monitoring. Its graphic LCD display and status LEDs provide a system-wide at-a-glance overview.

 

The Multi-Zone is a robust leak detector that offers effective refrigerant management. The earlier a small leak is detected, the sooner countermeasures can be initiated to mitigate costly refrigerant loss. With the on-board relays and the optional Remote Display, Multi-Zone fulfills the regulatory requirements as refrigerant detection system. Using the Modbus interface or analog output, the monitor can be integrated into any BMS/BAS system.
