Danfoss has released a new gas detector line for industrial refrigeration applications. According to the company, the detectors are based on a digital platform that delivers multiple communication and integration options for improved operational reliability, calibration and maintenance efficiency, cost-effectiveness, and regulatory compliance. The portfolio ranges from basic to heavy-duty models, complemented by a range of accessories.
The gas detection units can detect a wide range of refrigerant gases including ammonia (R717), CO2 (R744), fluorinated refrigerants (HCFC and HFCs), and propane (R290). The units come with various sensor technologies to match specific refrigerant, application, and safety requirements of the refrigeration system including electrochemical (EC), semiconductor (SC), Pellistor (P), and infrared sensors.
Officials also said the analog or RS485 Modbus connection enables easy communication to a central system. Stand-alone gas detection units with integrated relays are available and can be connected to external systems directly to activate alarm devices. To support a plug-and-play solution, all gas detection units come factory preconfigured to match refrigerant and typical PPM setting requirements. Depending on national regulations PPM settings may be subject to change.
