Dynamic Filter Efficiency (DFE) Testing by Scientific Services Inc.
Industry Standard, State of the Art, Hydraulic Testing Services for DoD and Industry
Welcome to DFE Testing by SSI
Who we are
SSI rests on the foundation of over 60 years of experience in the Fluid Power Industry. Our goal is to help client companies to develop effective contamination control solutions, and the products needed to successfully implement those solutions.
Charlie Juhasz, a recognized leader in the industry, has been a leader in developing Glass Fiber filter media, Metal Fiber filter media, and the manufacturing processes to turn these materials into high performance filtration products.
To advance the science and technology of contamination control we found existing industry practices, testing methods, and standards inadequate in today's dynamic environment. The fluid power industry needs a realistic, accurate, and repeatable method to determine the performance of a filter, and its effect on fluid cleanliness. We developed the test methods and equipment to provide a powerful tool for the industry for evaluating filter performance for effective contamination control. We call it Dynamic Filter Efficiency.
About the CCTS
The Controlled Contamination Test System (CCTS) has been developed by SSI to create a controlled contamination test environment to test under dynamic operating conditions, with all data including particle counts collected, recorded, and displayed in real time.
The CCTS is covered by the US patent No 6,453,257:
APPARATUS FOR TESTING THE ABILITY OF A FILTER TO FILTER CONTAMINANTS
Multiple functions and capabilities of the CCTS
•Filter testing
•Pump testing
•Servo valve and other hydraulic component testing
