QIRF Series Refrigerant

The QIRF refrigerant gas detectors are the second generation of QEL proprietary designed transmitter/sensors. They are configured easily to meet the International Mechanical Code, ASHRAE 15, and B52 requirements.

These transmitters were engineered to address the deficiencies inherent with solid-state sensors. Infrared technology facilitates specific gas type refrigerant detection without any cross-sensitive interferences.

Its sensing technology is a non-contact, non-depleting form of concentration measurement that has a sensor life of over ten years. Standard equipment includes a digital display, three user configurable relays, buzzer, horn/ strobe output and non-intrusive calibration.

Sensor housings are thermally controlled at elevated temperatures to eliminate errors due to condensate formation and from temperature fluctuations allowing operation in temperatures from -45ºC to +65°C. Each unit can be connected to either the M-Controller or Q4C controller through RS-485 digital communication allowing for cost effective wiring installation. Equally the transmitter is available with 4-20 mA, and Modbus outputs to any Building Automation System (BAS).

Controllers can be equipped with internal and external horns and strobes to alert personnel prior to entering the hazardous area. The M-Controller and is available with M-Net and M-Logger which allows remote monitoring, notification, programming and datalogging features.

NEMA 4X enclosures are standard.

Calibration procedures are straight forward, non-proprietary and can be performed by any competent technician. Consult the factory for specific gases.
