More than 1000 times better than bubble test
Our factory is equipped with 3 automatic Helium leak test equipment with a total of 5 vacuum chambers. Parts up to 1500x1000x1000mm can be automatically tested without the risk of human error. The machine automatically fill in the part with helium, which is a noble gas with molecules much smaller than air and an electronic spectrometer detects if there is a leak. The smaller detectable leak rate is 1,0 x 10-6 mbar liter /sec. Helium leak testing is today the most advanced testing method and it is far better than normally used bubble test.
100% of our parts and assemblies are leak tested using state of the art Helium leak test equipment, using the vacuum test or sniffing methods.
COOLTECH has a total of 5 different vacuum chambers in order to be able to test parts which have very different volume.
