Specification of BACHARACH HGM-MZ (3015-5044) Multi Zone Gas Leak Monitor
GAS ANALYZER
The Bacharach HGM-MZ Multi-zone Gas Leak Monitor offers 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). These state-of-the-art fixed gas monitors lead the industry in performance, integration capabilities, initial cost and cost of ownership. Capable of detecting more than 38 refrigerant gases, the Multi-Zone system is compliant with ASHRAE standard 15-2007, is ETL Energy Saving Listed, meets California Code Regulations for Refrigerant Monitors and is EN 14624 and CE certified.
The Multi-Zone is not only a leak detection system, but enables refrigerant management of e.g. a whole supermarket. The sooner a loss of refrigerant is detected, the earlier countermeasures can be initiated, resulting in smaller recharge quantities of refrigerants. With the on-board relays and the optional remote display, the Multi-Zone fulfills the regulatory requirements as a refrigerant detection system. Using the Modbus interface or analog output, the monitor can be integrated into any BMS/BAS system.
Bacharach HGM-MZ Multi-zone monitors provide continuous detection of refrigerant gas levels in up to 16 separate test zones and can be fitted with an optional two channel 4-20 mA current loop board for connection to remote monitoring equipment. Multi-Zone monitors retain a log of previous readings that can be easily accessed for analysis. Four relay contacts are provided that can be programmed to trigger external alarm devices in the event of a system fault, or if a leak (small), spill (medium) or evacuation (large) level of gas is detected, while audible and visual front panel indicators show alarm and fault conditions. With only minor periodic maintenance, such as the occasional replacement of filters, and active diagnostics that continuously check the system for proper operation, Multi-Zone monitors help maintain your equipment efficiency, promote safety and protect the environment.
