Plug-and-play gas detection for industrial refrigeration makes life easy
Danfoss gas detectors are based on a digital platform that delivers multiple communication and integration options for improved operational reliability, easy calibration and maintenance efficiency, cost effectiveness, and regulatory compliance.
Based on a digital platform, Danfoss gas detectors deliver multiple communication and integration options for easy calibration and maintenance, improved reliability, built-in cost effectiveness, and complete regulatory compliance.
With a portfolio ranging from basic to heavy duty, complemented by an assortment of accessories, and able to detect a vast range of refrigerants—including ammonia (R-717), CO2 (R-744), fluorinated refrigerants (HCFCs and HFCs), and propane (R-290)—Danfoss' Gas Detection Solution delivers great flexibility when designing and building a gas detection system. Featuring electrochemical (EC), semiconductor (SC), Pellistor (P), and infrared sensor technologies, these gas detectors are able to meet the unique needs of wide array of refrigerants, applications, and safety regulations.
Each gas detector includes analog and RS485 Modbus connections to enable easy communication to a central system. Stand-alone gas detection units with integrated relays are available and can be directly connected to external systems to activate alarm devices.
Features and benefits
Factory-configured gas detection units match refrigerant and typically required PPM settings
- PPM settings may be subject to change
Integrated calibration routine eliminates the need for potentiometers or multimeters
Plug-and-play design makes for easy replacement
Service information and alert support optimizes maintenance planning
