System Reduces Maintenance Time by 80%

New Kensington, PA – Bacharach, Inc., a leading provider of HVAC-R gas instrumentation, announces the introduction of the MGS-400 Series Refrigerant Gas Detectors for commercial and industrial refrigerant and gas leak monitoring applications. The MGS-400 series supports safety compliance inside of machinery rooms, chiller plants, cold storage facilities and walk-in freezers by monitoring for dangerous refrigerant leaks. The ability to detect refrigerant leaks and quickly initiate alarm systems helps to protect personnel and achieve compliance with safety standards like ASHRAE 15, CSA-B52 and EN 378.

MGS-400 Series Refrigerant Gas Detectors allow users to interface with the device using a mobile app, making configuration and maintenance simple and intuitive. Reducing commissioning and installation time, the MGS-400 delivers on efficiency and cost savings while allowing for plug-and-play, pre-calibrated sensor installation and replacement in the field. Simple installation and maintenance eliminates the need for lengthy, in-field calibration procedures that require multi-meters and manual adjustment of potentiometers.

The optional MGS-408 Gas Detection Controller supports up to eight sensor channels and enables a centralized alarm and power system. With Modbus connectivity, the controller integrates with any facility’s existing building management or automation system. The MGS-408 will also connect with Bacharach’s MGS-250 Refrigerant Monitor and the dual-sensor MGS-550, allowing for flexibility of individual site requirements.

“By focusing on new solutions, such as a mobile app user interface, and plug-and-play sensor technology, what used to take 25 minutes per gas detector now takes less than 5 minutes and can be done without training.”Tom Burniston, Product Manager

“We used our engineering expertise and long history of experience in refrigerant leak detection throughout the development of the MGS-400 product series. Our customers were asking for ease of use and easy installation and maintenance as an improvement to their current refrigerant detection systems. By focusing on new solutions, such as a mobile app user interface, and plug-and-play sensor technology, what used to take 25 minutes per gas detector now takes less than 5 minutes and can be done without training,” said Tom Burniston, Product Manager, Refrigerant Leak Detection. “By making the controller double as the power supply and using a daisy-chained Modbus, the unit requires only one cable hook-up, saving time and simplifying installation. Through our robust product development and our expertise in refrigerant leak detection, we are surpassing industry standards with this product series,” he said.

Engineered for Use in Refrigeration Applications

The MGS-400 has been engineered to help facility owners comply with safety standards in refrigeration applications:

  • Regulatory Safety ComplianceSupports compliance for ASHRAE 15-2013, CSA-B52 and EN 378:2016.
  • Reduced Installation Time and CostsQuick set-up using mobile app to configure alarms and Modbus settings, initiate calibration and tests.
  • Scalable SystemPower and connect up to 8 sensors with the controller.
  • Pre-calibrated SensorsPlug-and-play, in-field, pre-calibrated sensors.
  • Integrated AlarmsOn-board audible and visual alarms alert personnel to refrigerant leak.
  • Alarm RelaysHigh and low alarm relays initiate mechanical ventilation or additional horn / strobes.
  • Reduced Maintenance, Service and TrainingOn-board instrument diagnostics, “Service Due” indicator and sensor exposure counter enable effective pro-active maintenance programs
  • Intuitive User InterfaceMinimal training required to commission gas detectors or perform calibration.
  • Optimized PerformanceTemperature-compensated measurement of natural refrigerants and halogens minimizes false alarms.
  • Calibration Certificatesmaintain an audit trail.

Demo MGS-400 Series Gas Detectors at Chillventa

The MGS-400 Series will be on display in Hall 5 / Stand 5-408 at the Chillventa International Exhibition from October 16 – 18. Bacharach invites conference attendees to speak with their representatives about refrigerant safety standards and demo the MGS-400’s intuitive user interface.
