CCDI Airflow Leak Detection

		Model 70 The Model 70 is not developed for turbine airflow. However, it can be adapted to many industries: 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. It uses a charge pressure vessel and uses pressure decay along with barometric pressure and temperature transducers to calculate the volumetric leak rate. We can offer this unit using mass flow sensors or orifices as well, tailored to you needs. The computer and monitor are built into the box and can be set up as field test unit as well.

		Model 77 The CCDI Model 77 was developed for leak testing A-B plates of turbine fuel/exhaust heat exchanger units used of the M1 Abrams tank. It pressurizes the plates at 10 PSIG and measures 0-50 SCCM air flow. 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.
