Danfoss GD gas detectors

The series of gas detectors Danfoss GD includes models from Basic to Heavy Duty, complemented by a range of accessories. Gas detectors GDU can detect a lot of refrigerant types including ammonia (NH3/R717), CO₂ (R744), fluorinated refrigerants (HCFC and HFC) and propane (R290).

They are offered with a variety of sensor types, that meet the specific refrigerant , application conditions and safety requirements of the refrigeration system, including electrochemical (EC), semiconductor (SC), pellistor (P) and infrared (IR). The analog connection or connection via Modbus provides easy communication with a central system. Autonomus gas analyzers are available with built-in relays which can be directly connected to external systems to activate alarm devices.

Advantages of the gas detectors Danfoss GD:

• Factory preset to suit refrigerant and typical PPM requirements
• Pre-calibrated and easy to replace Plug & Play sensors.
• Service interval information and service alerts support optimized maintenance planning
• Digital interface provides better accuracy and simplifies operation of the device
• Automatic self-diagnosis ensures correct communication and operation between the devices and the system.
•  Reduced risk of false alarms thanks to temperature compensated sensors (EC, P, IR). 
• In order to improve work safety, defective sensors with a too short life expectancy (<30% sensitivity) are rejected during the calibration process.
