LEL/UEL Apparatus Provides Compliance of Gases using ASHRAE 34 Guidance

Sigma-HSE have upgraded our LEL/UEL system to provide specialised testing compliance of refrigerant gases using ASHRAE 34 Guidance. This makes us one of a small number of European test house that can provide video of ignition for this particular test.

Our existing LEL/UEL System can provide determination of the Lower Explosion Limit (LEL) / Lower Flammable Limit (LFL) and Upper Explosion Limit (UEL) / Upper Flammable Limit (UFL) for gases and vapours, either individual substances or mixtures. This data is essential for assessing risks in processes involving flammable liquids.
