Develop a production line solution to detect and repair leaks prior to hot testing. Eliminate the possibility of leak-associated defects getting through the system. Deliver accurate results in seconds, while not wasting time and money on hot test repeats.
InterTech M1075 – for unsurpassed leak testing speed and accuracy
The InterTech Solution
InterTech M1075 dry air tests both the water side and the oil side of an engine block at the same time, up to twice as fast as other available options.
The water side includes engine block passages, water pump, heater housing, thermostat housing, associated hoses and the coolant half of the lube-oil cooler, creating a cavity of about 12 liters. The oil side includes engine block passages plus, front and rear gear fly wall housings, crankshaft seals, oil pan, intake manifold and the oil half of the lube-oil cooler.
This creates a cavity of up to 180 liters depending on engine model. The InterTech testing system avoids problems of pressure fluctuation in the supply line by using isolated air reservoirs. Because it is independent of plant air supply, it provides a direct and stable measurement of leakage.
The InterTech system simultaneously pressurizes both cavities and the reservoirs: the oil cavity to 2.5 psi with a reject limit range of .2 lpm to1.4 lpm (user selectable); and the water cavity to 10 psi with a reject limit of 25 sccm.
Any leakage causes the leaking cavity to lose pressure and the InterTech mass flow transducer reads the flow rate.
