Danfoss 080Z2830 Gas Detecting Sensor

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 with environmental F-Gas Regulations and 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: HFCs, HCFCs, CFCs
• carbon dioxide (CO₂/R744)
• hydrocarbons (e.g. R290)
• other special application gases to customer request

Sensing technology varies to make the best detection for a given gas, in terms of performance and cost. DGS-IR is based on infra-red sensor technology, DGS-SC is based on semi-conductor and DGS-PE is based on pellistor.
