Danfoss Gas Detector (R404A/R507)

Environmental requirements increasingly demand improved protection and responsibility of End Users applying
refrigerants in their systems/plants. This has been supported by Governments with new laws and local regulations to ensure correct handling and responsibility.

Utilising either Semi-Conductor (SC) or Infrared (IR) technologies, DGS gives quick and immediate response in detecting a wide range of different gases typically applied in Refrigeration & Air Conditioning systems.

Danfoss is now adding Modbus integration with our System managers for cost efficient installation, continuous monitoring and ease of use.


DGS sensors can be used in stand-alone or integrated systems, where continuous real-time, automatic monitoring with Danfoss ADAP-KOOL® Refrigeration Control & Monitoring System and/or
Building Management Systems is applied.
DGS supports our Customers in complying to environmental F-Gas Regulations and/or Health &
Safety requirements, on new or existing systems in:
• Supermarkets
• Process refrigeration plants
• Refrigerated storage and warehousing
• Special application areas/zones
Typical Refrigerant gas applications include:
• Halocarbons: HFC’s, HCFC’s, CFCs.
