MGS-450 Gas Detector

Safety Gas Detection for Refrigerants, Toxic and Combustible Gases

Bacharach’s MGS-450 Gas Detector makes compliance with refrigeration safety codes (ASHRAE 15EN 378CSA-B52) simple and effective, saving time and money on equipment and installation.

  • Optional IP41 or IP66-rated enclosures protect from dust and water ingress
  • Plug-and-play pre-calibrated sensor modules allow for quick, simple sensor replacement
  • Temperature-compensated measurements mitigate false alarms and optimize accuracy in refrigeration applications (suitable for use in cold rooms and freezers down to -40°C)
  • Configurable analog output (4-20mA, 0-5V, 0-10V, 1-5V or 2-10V) and Modbus communications for integration with Bacharach’s MGS-408 controller or third-party BMS / BAS control systems
  • Three user-configurable relays (fault, low and high alarm) may be used to activate external beacons / sounders, ventilation or other countermeasures
  • Integrated audible / visual alarms for refrigeration safety compliance – no additional hardware required
  • MGS-400 mobile app (available for Android and iOS) allows users to interface via Bluetooth® with gas detector for easy commissioning and maintenance without specialty tools or training

Description

Bacharach’s MGS-450 Gas Detector makes compliance with mechanical equipment room and refrigeration safety codes simple and easy, saving time and money on equipment and installation. Using the MGS-400 App, users can intuitively use, commission and maintain their gas detection system without the need for specialty training or tools. Pre-calibrated sensor modules simplify maintenance, take minutes to exchange and do not require the use of calibration gas. The MGS-450 sensor can trigger additional audio-visual alarms and act as a standalone gas detection system, or integrate easily into a BMS / BAS or with Bacharach’s MGS-402 or MGS-408 Gas Detection Controllers.
