Danfoss is introducing a new range of fixed gas detectors for industrial refrigeration applications. The company says the gas detectors are based on a digital platform that delivers multiple communication and integration options for improved operational reliability, easy calibration, and maintenance procedures that enable high service efficiency and regulatory compliance. Additionally, the user-interface aims to provide a high level of accuracy to simplify operator handling that minimizes operational, settings, and calibration error risks. The portfolio ranges from basic to heavy duty models with sensor technology to match the specific refrigerant, application, and safety requirements of the refrigeration system.

The analog or RS485 Modbus connection helps to enable 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 provide a strong plug and play solution, all gas detection units come factory pre-configured to match refrigerant and PPM setting requirements.

For a more simplified calibration process, the new range of Danfoss gas detection units have an integrated calibration routine. Gas calibration no longer requires potentiometers and multimeters, simplifying the process significantly and reducing calibration time and the risk of errors. Pre-calibrated and factory certified sensor replacements are available across all sensor types.

Several service features support optimized maintenance planning such as service alerts —on the unit, the controller, or both — to indicate when service is due. The dedicated PC tool provides an overview of when each gas detection unit operates as well as generates field calibration reports to support safety documentation and procedures.
