We custom design the recuperator as per customer requirement. Recuperators manufactured by us will have good effectiveness. We make Shell & Tube of 2-pass, 3-pass, 4-pass heat exchangers.
In a recuperator both mediums are separated by a wall through which heat is transferred directly. The only fundamental loss hereby is the heat conduction through the wall in the flow direction. However, this can be reduced by using insulating materials having low heat conductivity.
