We repair and test every damper according to its original specifications, certificates of conformance as well as test logs and damping curve print outs for every damper overhauled are available upon request. All dampers are tested using our Computer Aided Control (CAC) Damper Testing machines, each Force vs. Displacement chart (as below) is then inspected for irregularities and the damping forces are set to the correct value.
