Gas Leak Detection and Alarm Systems

Aqualeak supply, install and maintain a range of gas leak detection systems and control panels, to help customers comply with an array of refrigerant, toxic and combustible gas safety standards. We offer a number of different system options, from single standalone gas detectors, to controllers providing central monitoring for multiple sensors.

Gas leak detectors available from Aqualeak are suitable for a range of applications, including hazardous areas, machine rooms, walk-in freezers and cold stores, through to occupied spaces with cooling and heating systems, such as hotel rooms, hospitals, offices and apartment blocks. Our systems reduce the risk of the unwanted and dangerous concentrated presence of gasses, providing early warning signs and quick prevention measures.

Our refrigerant gas detection systems can also help customers meet the relevant requirements of BREEAM criteria, subject to a successful audit by an authorised, third-party assessor. The implementation of these types of systems can help you achieve BREEAM credits, demonstrating the environmental and sustainability credentials of your property.

Gas Leak Detectors

MGS-450

Refrigerant, toxic and combustible gas detector

  • Cost effective and simple-to-use fixed gas detector that helps customers comply with a range of refrigeration safety standards, including ASHRAE 15, EN 378 and CSA-B52
  • Can be used as a standalone detector or connectable to multi-detector controllers such as MGS-402 and MGS-408
  • Integrated audible / visual alarms for refrigeration safety compliance
  • 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
  • Configurable analog output and Modbus communications for integration with 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 counter-measures
  • MGS-400 mobile app (available for Android and iOS) allows users to interface via Bluetooth with gas detectors for easy commissioning and maintenance without specialty tools or training

Example applications: Machinery rooms, cold storage rooms, walk-in freezers, food preparation areas

MGS-402

2-channel refrigerant, toxic and combustible gas leak detection controller

  • Central status monitoring controller of up to two MGS-450 gas detectors, to alert to the presence of refrigerant, toxic and combustible gases
  • Tri-colour LED indicators provide “at-a-glance” system / alarm status
  • Integrated audible / visual alarms with push button silence for refrigeration safety compliance
  • Designed for operation in refrigeration applications, suitable for use in environments down to -40°C
  • Two configurable analogue outputs and Modbus communications for integration with the MGS-408 controller or third-party BMS control systems
  • Three user-configurable relays (fault, low and high alarm) may be used to activate external beacons / sounders, ventilation or other counter-measures

Example applications: Machinery rooms, cold storage rooms, walk-in freezers, food preparation areas

MGS-408

8-channel refrigerant, toxic and combustible gas leak detection controller

  • Central status monitoring controller of up to eight MGS-450 gas detectors, to alert to the presence of refrigerant, toxic and combustible gases and help comply with refrigeration safety standards such as EN 378 and ASHRAE 15
  • Digital display shows real-time concentration readings for all connected gas detectors and makes configuration and self-diagnostics intuitive
  • Tri-colour LED indicators provide “at-a-glance” system / alarm status
  • Integrated SD card retains the alarm / status history of the gas detection system
  • Modbus communications for integration with third-party BMS control systems
  • Integrated audible / visual alarms with push button silence for refrigeration safety compliance
  • Three user-configurable relays (fault, low and high alarm) may be used to activate external beacons / sounders, ventilation or other counter-measures

Example applications: Machinery rooms, cold storage rooms, walk-in freezers, food preparation areas

MVR-300

Refrigerant gas detector for occupied spaces

  • Specifically designed to provide continuous monitoring for refrigerant gas associated with high-efficiency, high volume refrigerant cooling and heating systems, such as Variable Refrigerant Flow and Variable Refrigerant Volume) systems
  • Audible and visual alarms to quickly alert occupants, while simultaneously communicating with BMS/BAS
  • Two relays that can be used to initiate counter-measures, such as valve closure, trigger alarm devices and exhaust fans
  • On-board Modbus RTU interface provides real-time information about concentrations, status and settings. It also enables custom configuration of the MVR-300 to any application specific requirements using multiple Modbus registers
  • Fits in standard 3-gang electrical boxes for easy installation
  • Low profile / flush mount for aesthetically non-intrusive appearance
  • Self-diagnostics and simple field calibration for easy maintenance
  • Unique plug-in field replaceable pre-calibrated sensor for low cost of ownership

Example applications: Hotels, dormitories, hospitals, office buildings, apartment buildings
