BEAM SAU Ducting & Valves


Beam only use precision engineered metal and plastic fittings, ducting and silencers, mechanically fastened and sealed at every joint. 200-125mm insulated (in cold spaces only) smoothflow rigid ducting provides higher heat efficiency, low pressure loss resulting in a lower energy use and the system will be quieter due to efficient low velocity. This solid ducting is resistant to crush damage and thereafter can be cleaned and maintained if required.
