PPM 470 Leak test bench with gas
The leak test stand is suitable for gas pressure tests up to 1050 bar. Tests can be performed with 95/5 moulder gas/H2, helium or nitrogen. Standard 50L gas cylinders or other sources serve as the media source. A leak is detected and registered by a sniffer (e.g. Inficon P3000XL).
The leak test stand is equipped with a special safety concept to protect the operator. New and never before components and prototypes are tested with water in a safety chamber for their bursting pressure (e.g. up to 3000 bar) to understand the component’s behaviour.
A safety box is installed in the climate chamber for testing with gas, which protects against potential component splinters. In addition, various flexible hoses are attached to the box and are equipped with nozzles to detect leakage at several points around the component. Consequentially, the hoses are connected to outlets outside the climate chamber. At the outlets, the operator can use the sniffer to identify the leak. For an underwater test, the safety box is removed or the door of the box is hung out. Frequently tested components in this system are H2 Ontank Valves.
