After repeated requests from aircraft manufacturing firms, airplane engineers and aerospace filter manufacturers, IFTS has invested and developed a highly accurate cryogenic filter test chamber.
The complete test system and associated equipment, is housed in a fully insulated cold chamber which allows in depth filter tests at temperatures as low as -40°C, flow rates up to 50 gpm (200 L/min), and at differential pressures up to 90 psid (~6 bar). The flexibility of the system design allows us to perform various custom test configurations. This might include the filter and all its associated components tested within the cold chamber at a constant low temperature, or another popular method is where all equipment is held outside the chamber at ambient temperatures and only the test filter is inside at the low test temperature.
As an example; a recent test program consisted of monitoring the clogging and physical behavior of kerosene filters in the presence of trace water in kerosene at -45°C and a flow rate of 50 L/min. Water was injected upstream the circulation pump to create an emulsified test fluid and ∆P was continuously recorded until the end of test value was reached. The results provided an in depth and unique view of these challenging conditions.
