Danfoss Gas Sensor (DGS)

Introduction

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 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.

• 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.
