Gas detection for commercial refrigeration

Updated gas detection sensors, same reliability 

You get the same proven reliability, standards compliance, and safety as with the previous DGS series, but with a faster response time. An extra relay is added for early warning of a rising gas concentration. The option of adding an external push button allows convenient testing of the gas alarm system before entering a sensor-protected area.

The new DGS series is based on an all-new digital platform, making it easy to install and use. Sensors can easily be integrated into Danfoss ADAP-KOOL® systems, giving you 24/7 remote service access to parameters and alarms. The new DGS series gives you long calibration intervals for reduced maintenance costs, and sensor heads are easily replaced with a simple plug-and-play process.

With the new DGS series just 5 models but covers 15 refrigerants, including propane with the pellistor sensor variant (DGS-PE). You can get a wide range of accessories like replacement sensor heads, strobes-and-horn, splash guards, a remote kit and duct set, and a calibration kit. A low-cost-variant without built-in buzzer and light is also available for mounting in an electrical panel or in the plant room.

You can easily upgrade the old DGS series to the new one; this requirement was a major priority when Danfoss developed the new series.
