Auxiliary Power Unit (A.P.U.) Bellows
Auxiliary Power Units (A.P.U.) are smaller engines that power vehicle subsystems. They are chiefly employed to start larger turbine systems on aircraft or as a cost effective alternative to running primary power systems on a diesel truck, like a sleeper cab or a trailers’ refrigeration system.
Senior Flexonics manufactures A.P.U. bellows and A.P.U. bellows assemblies for these types of applications. We provide many customers with complete systems allowing for “drop in” assembly.
