DUCoaT – pipes and ducts with Halar-interior-coating are used in exhaust air facilities where highly aggressive exhaust process air from the machines is released into the atmosphere through the scrubber system. Available standards for pipes, fittings, connecting systems and special components, such as multi-leaf dampers and silencers, are compiled in our planning folder. Upon request we are happy to inspect rectangular systems and special parts, such as scrubbers, tanks and customer drawings to verify that they conform to FM regulations and stability.
