Deaerator Types

Kansas City Deaerator Company designs a complete line of Deaerator Types and Sizes, from Spray to Tray deaerators, smallest to the largest in the world.


Tray deaerators are the ultimate choice by all reputable Consulting Engineers all over the World. Tray Deaerators ( Only Counterflow types, not Parallel Downflow Types) are the only Deaerators approved by the Heat Exchange Institute HEI as they keep all gasses contained in Stainless Steel to protect the Carbon Steel vessel from Corrosion. Tray Counterflow deaerators are the Gold Standard and choice of most owners where longevity and trouble free operation is needed for over a 25 year life. Spray Deaerators and Counterflow Deaerators simply do not meet the requirements of the HEI.
