With more than 140 benches currently testing the tightness of car cooling circuits, HeTECH/MARPOSS can be considered as a specialists in testing this type of component.
Our benches have the right technology to test all types of air conditioning hoses: single, double, bundle and coax. On this last model, hoses are tested to detect leaks between internal and external hoses and in external hoses towards vacuum chamber. Low pressure and High Pressure test can be performed on all our leaking units.
Should a chamber house several cooling circuits, the software our leaking systems are equipped with allows to choose whether to test simultaneously on all circuits or individually.
