At Ruskin’s AMCA Accredited Lab located in Grandview, MO, leakage and cycle testing is conducted to some of the industry’s most stringent requirements such as frame leakage heavy duty industrial projects. By applying plates to both sides of the damper frame and pressurizing to a specified capacity, the damper is closely inspected for leaks using a glycerin and water solution sprayed on the damper exterior frame and weld areas. This validates that anything in the air stream stays in the airstream not to atmosphere.
Control of the interior air path is just as critical as containment. Each damper is subjected to duct mounted flow testing to meet certain seat leakage and pressure drop requirements. This could be as simple as an open close cycle test, or testing pressure drop at certain blade angles at specific velocities.
Testing to ASME and NQA quality requirements are also within Ruskin’s capabilities. Should these standards and programs be invoked, Ruskin Lab Technicians isolate and segregate dampers during testing and storage. If the dampers are constructed of various grades of stainless steel, care is taken so as not to contaminate the dampers with carbon or any other material that would jeopardize the purity of the stainless. This includes such details as the type of tools and clamps Ruskin technicians use to perform testing. Versatility, knowledge and state-of-the-art testing equipment keep Ruskin ahead of the competition in high performance industrial systems.
