The Model 70 is a complete system designed to test airflow leaks of a wide range of turbine engine components.

The CCDI Model 70 was first designed to test hollow EDM probes for the semiconductor industry for measuring a 0.007" diameter cooling passage and reporting the leak rate. The machine reports the test result in volumetric flow units. Using a charge pressure vessel, pressure decay along with barometric pressure and temperature transducers to calculate the volumetric leak rate. We can offer this unit using mass airflow sensors or orifices as well, tailored to you needs.

The Model 77 is a complete system designed to test airflow leaks of a wide range of turbine engine components.

The CCDI Model 77 was custom developed for leak testing A-B plates of turbine fuel/exhaust heat exchanger units used on the M1 Abrams tank. It pressurizes the part that is under test and measures 0-50 sccm airflow leakage. The unit is comprised of 20 Mass Flow Sensors, calibration reference orifice, a pneumatically controlled ram for the pressure chamber, transport unit and guard door. The loading and unloading sequence is all computer controlled and can also store results on a network ready computer.
