This unique combination makes ARVOS Group one of the leading experts providing best-in-class heat exchanging solutions and advanced lifetime services. An air preheater (APH) is any device designed to heat air before another process (for example, combustion in a boiler) with the primary objective of increasing the thermal efficiency of the process. The seals allow the element to rotate through all the sectors, but prevent gas leakage between sectors while providing separate gas air and flue gas … It was invented in the early part of the 20th Century as a means of recapturing heat escaping up the flue stack in boiler systems.
