The Cincinnati Sub-Zero USD-10 is an environmental test chamber engineered to simulate sand and dust conditions for validating seal integrity and ingress protection in automotive and electronic components. The system operates by pulsing compressed air through a bottom manifold, directing dust upward and across the test specimen in a controlled chamber environment. Air pulse cycles—both on and off intervals—are programmable to meet specific test requirements. Dust concentration is adjusted by varying air pressure and blowing duration, enabling precise exposure control across the full test sequence.
