Multi-Zone Refrigerant Monitor
Bacharach’s Multi-Zone Refrigerant Monitor provides precise measurements of low-level refrigerants and naturals carbon dioxide and ammonia.
The continuous monitoring of ammonia, CO2 and synthetic refrigerant gas provides fast and early refrigerant leak detection, ensuring compliance with refrigeration safety standards and emission regulations.
Bacharach’s Multi-Zone Refrigerant 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.
Infra-red sensor technology provides accurate measurements of low ppm levels and is unaffected by other gases, humidity and temperatures.
Accurately detects leaks in up to 16 separate areas, which can expand to 48 monitoring points, ideal for grocery store refrigerant monitoring.
