Gas Detection Products for Industrial, Hazardous Areas & Explosive Atmospheres

Single & Multi-Gas Detectors for Flammable, Toxic & Oxygen Gases

Fixed gas detectors manufactured by Crowcon have been proven in many harsh environments around the world and are used in industries such as offshore, oil and gas, petrochemical as well as steel mills and chemical plants.

The benefits of installing a fixed gas detector are they can be hard wired resulting in constant power and no potential loss of detection. This provides an extra amount of safety and is an obvious choice for zones that are almost constantly at threat from the presence of gas.

Anywhere there is a potential threat from gas, a fixed gas detector can be installed to protect both personnel and plant. Crowcon fixed gas detectors provide a reliable, stationary level of protection against harmful gases and can be used in conjunction with the range of Crowcon portable gas detectors.

The range of gas detectors from Crowcon are suitable for detecting single and multi gases and can be configured to suit specific requirements – including hazardous area workplaces according to ATEX and IECEx Certification.

When designing and specifying fixed gas detection systems several criterion must be considered including: what gases and concentration level is present, is the gas lighter or heavier than air, are fixed gas detectors suitable, could infra-red gas detection technology provide optimal plant safety?
