At VES we have designed a full package of machines to meet all the requirements for leak testing these high-pressure tanks. Starting with a vacuum drying station to meet stringent moisture content requirements. Moving on to a fully automated accumulation machine with built in point detection to meet the required leak rates and cycle times.
Accumulation machines work in atmospheric conditions using either forming gas or tracer gas; working without a vacuum chamber an accumulation tester provides accurate, repeatable and reliable results at relatively low cost. While VES have also introduced different testing gases, been able to provide a solution that is up to 94% cheaper per test piece than traditional 100% helium.
A unique design, developed in house at VES, specifically for high pressure applications (including Hydrogen and CNG tanks). The H2 Safe machines have been designed to incorporate three different elements:
