Leakage Detection in Coating Equipment - Details on Best Practice Based on long term experience the authors give practical advice to users/operators to find the optimum installation, positioning and operation of the Helium leak detector for leak detection on a coating/metallizing plant and its gas supply system. Physical effects and dependencies are explained influence the response and whichrecovery times. The use of auxiliary pumps for evacuation of larger volumes and the partial flow ratio resulting from this procedure are discussed. General advises complement the article. [ABSTRACT FROM AUTHOR]
