Crowcon F-Gas Detector

01 July 2014

Crowcon’s F-Gas Detector lowers total cost of ownership by providing fast, stable and dependable performance with infra-red technology.  Unlike semi-conductor type sensors, infra-red is not affected by changes in temperature or interference by other gases.  Crowcon’s superior IR sensor is able to provide stable and reliable performance and low maintenance, making the Crowcon F-Gas Detector more cost-effective in the long run.

Fluorinated greenhouse gases (F-Gases) are widely used in the food and drink industry, as coolants in cold-room storage, temperature controlled production environments, the larger retail refrigeration systems used in supermarkets and transport refrigeration. In the EU, Regulation 842/2006 mandates leakage control and regular checks on F-Gases usage. Effective monitoring and detection of these gases is essential.

Many F-Gases have very high Global Warming Potentials (GWPs) so a small amount in the atmosphere can have a large effect on global temperatures.  They are toxic as well as being a potential suffocation hazard, so represent a significant risk to personnel if inhaled. Leakage can also mean a substantial economic cost to the industry, since F-Gases are very costly chemicals. 

The Crowcon F-Gas Detector utilises a high quality infrared (IR) sensor specifically calibrated to detect the F-Gases commonly in use.  The tri-coloured LEDs that indicate the operating status make it easy to operate.  Push-button controls facilitate simple adjustments like zeroing and calibration. 

The product requires very little maintenance; a bi-annual gas check (with re-calibration if necessary).  This is made easy as the F-Gas Detector uses a two-part enclosure which is opened by releasing two tabs on the side.  Once opened, the field cable connector can be accessed on the top right corner. 

Housed within an IP54 rugged enclosure, as part of a compliance system, these F-Gas Detectors are usually connected to a building control system.  The output signal can be set to suit virtually any control system.  It operates from 24Vdc nominally, and provides a 4-20mA signal.  There are no consumable parts within the detector, and it thus can be expected to provide many years of service.
