FAQ‘s about Dräger's fixed gas detection

What is a fixed gas detection system?

A fixed gas detection system is a permanently installed setup designed to continuously monitor specific areas for hazardous gases in the air. It typically includes sensors, controllers, and alarm systems to detect and respond to gas leaks. Fixed gas detectors use sensors to measure gas concentrations in the air. When gas levels exceed predefined thresholds, the system triggers alarms and can activate safety measures to mitigate risks.

Some typical fields of applications:

Tank Farms: Where gases or liquids with flammable potential are stored.
Wastewater Plants: Use chemical substances for disinfection and reprocessing, such as Cl₂, SO₂, O₃, and ClO₂.
Food & Beverage Industry: Ammonia is used for cooling.
Pharmaceutical Industry: H₂O₂ vapour is used for sterilisation.

Can fixed gas detection systems be customised for specific applications?

Yes, Fixed Gas Detection Systems can be tailored to meet the specific needs of different applications. Dräger offers customisable solutions that can be designed to fit the unique requirements of various industries, ensuring optimal safety and performance.

Does Dräger support with consulting and planning?

Yes, Dräger delivers complete end-to-end consulting – from design to equipment specification and installation guidance. Our specialist teams have full in-house capability to assess hazardous environments in any application. They use proactive analysis, including advanced technology such as flame/gas mapping and custom wireless solutions, to develop a suitable solution for your specific needs.

Does Dräger offer gas detection training and customer support?

Certainly. Our training courses give you a better understanding of hazardous gas environments and effective usage of our gas detection systems. We can provide customised onsite training to meet your specific needs or at our facilities in many locations around the globe.

See our training offers

Dräger also provides support for your project or application, including technical queries and guidance on all aspects of our product and service portfolios, such as onsite after-sales service to maintain or repair your gas detection system. Just get in contact with us!

What is LEL gas measurement?

LEL (Lower Explosive Limit) gas measurement refers to detecting the lowest concentration of a gas that can ignite in air. Fixed gas detectors measure gas concentrations as a percentage of the LEL to prevent explosive hazards.
