Plug and play gas detection

DENMARK: Danfoss has introduced a new range of fixed gas detectors for industrial refrigeration applications.

Described as plug and play, these digital gas detectors are said to offer multiple communication and integration options for improved operational reliability and ease of calibration and maintenance procedures.

Additionally, the user interface provides a high level of accuracy to simplify operator handling that minimises operational, settings, and calibration error risks. The range covers basic to heavy-duty models with sensor technology to match the specific refrigerant, application, and safety requirements of your refrigeration system.

The 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 said to be available across all sensor types for easy service.

A wide range of refrigerant gases can be detected including ammonia, CO2, fluorinated refrigerants (HCFC and HFCs), and propane. They come with various sensor technologies to match the specific refrigerant, application, and safety requirements of the refrigeration system including electrochemical, semiconductor, pellistor and infrared sensors.

The analog or RS485 modbus connection is said 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.
