- Fixed Systems
When lives and property are at risk and you need gas detection equipment that is totally reliable, you need Crowcon. Fixed detectors have been proven in many arduous environments, including oil and gas exploration, water treatment, chemical plants and steel mills. They are however also chosen in many other applications where reliability, dependability and lack of false alarms are valued, for example in the automotive and aerospace manufacturing sectors, on scientific and research facilities and in high-utilisation medical, civil or commercial plants.
Crowcon use a variety of measurement, protection and communications technologies to offer a flexible range of products able to measure flammable, toxic and oxygen gases, report their presence and activate alarms.
Xgard Fixed Point Gas Detector
The Xgard range is a comprehensive selection of fixed point gas detectors that meet the diverse requirements for gas detection in industries throughout the world. This includes many water treatment, oil and gas, power, research facility and manufacturing installations.
Intrinsically Safe (I.S.) or Flameproof (Exd) versions are available, with case options comprising high-grade alloy, stainless steel or chemically resistant GRN polymer. Certifications include IECEx, ATEX, UL, GOST-R and MED.
Wide range of sensors:
Poison resistant pellistors, for all flammable detection needs including hydrocarbons, hydrogen, ammonia, jet fuel, leaded petrol and vapours containing halogens.
Electrochemical sensors are used to detect a vast range of toxic gases and oxygen.
Thermal conductivity sensors are available to monitor % volume concentrations of gases
Crowcon's 40+ years gas detection expertise has been instrumental in developing a range of control panels properly suited to their application. Combined with a variety of detector types, they offer a flexible range of solutions able to dependably measure flammable, toxic and oxygen gases, report their presence and activate alarms or associated equipment. Crowcon fixed gas monitoring systems are designed to be interfaced with manual call points, fire and gas detectors and distributed control systems (DCS). In addition each system can be engineered to drive remote annunciators and mimic panels.

Toxic Hydrocarbons & Organic Solvents
An MOS sensor consists of a heated mixed metal oxide element that decreases in resistance in the presence of many gases and vapors. These sensors are broad range in their response characteristics. Different types of MOS sensors are available which can be optimized for a particular gas, but they are inherently nonspecific. The EX-5155 can provide ppm level monitoring capability for detecting certain common toxic gases, including ammonia (NH3) and hydrogen sulfide (H2S), in addition to a wide range of hydrocarbons and organic solvents. MOS sensors operate at lower temperatures than catalytic type sensors, which makes them less prone to poisoning.
