F-Gas Infrared Detector

Crowcon Detection Instruments Ltd has launched a new F-Gas Infrared Detector for dependable detection of refrigerant gases. F-gases or fluorinated (Freon) gases, which include hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), hydro-chlorofluorocarbons (HCFCs) and sulphur hexafluoride (SF6), are a family of man-made chemicals containing fluorine. Not only are F-gases harmful to the environment, they are also extremely toxic and represent a significant health risk if inhaled. SF6 also poses an asphyxiation risk as, once inhaled, it may be too heavy to expel from the lungs. Effective monitoring and detection of these gases is essential. Crowcon’s F-Gas infrared detector is a fixed-point detector specially calibrated to detect a wide range of F-gases. Rugged and easy to install, it can be connected to any control system, which accepts analogue signals. Together with Crowcon’s Gasmaster control panel and Xgard toxic gas detector, the F-Gas detector provides an effective gas leak detection package. In addition to protecting personnel from toxic gas risks, installing the F-Gas detector also offers the following benefits: provides an early warning that the gas is leaking and thus maintains system efficiency and reduces potentially huge gas replacement costs; enables the supplier and user to comply with the mandatory F-gas regulations; and helps to reduce the risk of leakage of powerful greenhouse gases into the environment. The detector operates from 24 V DC nominally and provides a 4-20 mA signal (the output can also be set to 0-20 mA, 0-2 V, 0-5 V or 0-10 V DC). It is compatible with most control systems or 4-20 mA type controller. Housed in a rugged IP54 enclosure, the detector is suitable for use in non-hazardous areas such as plant rooms or switchgear rooms.
