MGS-460 Leak Detection System

Safety Gas Detection for Refrigerants, Toxic and Combustible Gases

Bacharach’s MGS-460 Gas Detector makes compliance with refrigeration safety codes (ASHRAE 15EN 378CSA-B52) simple and effective, saving time and money on equipment and installation.

  • IP66-rated enclosure protects from dust and water ingress
  • Remote sensor allows installation in hard-to-reach / elevated locations (distances up to 5m from the transmitter)
  • 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

Product Information

Bacharach’s MGS-460 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-460 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.
