Gas detection for boiler rooms, aero thermal heaters and co-generation

Types of gas detected: H₂ - CH₄ - C₃H₈ - C₄H₁₀

DALEMANS systems are designed to detect hydrogen, methane, propane and butane gas. DALEMANS solutions offer double protection with an alarm being set off at 20% LEL and an automatic closure of the gas solenoid valve programmed at 40% LEL.

Position of the detectors

The position of the detector is adapted according to the density of the gas. For the detection of hydrogen and methane, the detector will be placed on the ceiling, while for butane and propane, the detectors will be placed on the floor.

Commissioning and maintenance

Directly or through your fitter, DALEMANS carries out the commissioning and maintenance of your gas detection system.
