Ideal for Chiller Rooms, Supermarkets, Brewing and
Bottling Facilities, Industrial Refrigeration, Arenas,
Food Storage and Processing Facilities.

Features & Benefits:

Stand-alone, out-of-the-box solution with quick and easy
installation - the most cost-effective system available.

Fast-response sensors detect leaks quickly, which
minimize refrigerant gas usage and environmental impact.

Infrared (NDIR) CO2 detection

Long-life semiconductor sensors for detection of all
refrigerants, ammonia, halocarbons, combustibles & VOCs

Robust design allows units to be placed directly in areas
where detection is needed.

Available in a variety of housings, including IP66 and duct
mount.

Select from 1, 2, 4 or 6 remote sensors and 1 or 2 pre-set
alarm levels, which can be connected to BMS systems.

Flexible and Dynamic Continuous Monitoring

Bacharach’s MGD-100 Series is a robust and scalable gas detection system used for
reliable real-time monitoring of refrigerant, combustible, and toxic gases. It’s a
stand-alone system that alarms when pre-set thresholds are exceeded. The MGD-100’s
alarms are monitored by a centralized controller, which can alert personnel of potential
hazardous conditions via an onboard buzzer and LED alarm indicators.

MGD-100 Systems can be configured from single-sensor, one-alarm level systems to
larger scale systems consisting of 6 sensors with 2 alarm levels. This flexibility allows the
platform to be used for both small and large systems. Optional MGD-100 housings are
shown below:
