Counter-flow heat exchanger

WWB-1/S-1, WWB-2/6.50/JAD, WWB-3/3.18/JAD, WWB-4/5.36/JAD




Purpose

Counter-flow heat exchangers are installed on district heating substations that supply inner installation of central heating and usable hot water demand in residence buildings. Heat exchangers are supplied from external heating network and may be used individually or in a group system.

Technical Description
WHeat exchanger is made of corrosion-proof steel, as welded construction. It is in a form of external cylindrical blanket closed with two heads with welded flanged ferrules. Two another flanged ferrules are welded into the blanket. Inside the blanket there is a tube insert constructed of two perforated bottoms connected with O 8x0,6 mm tubes' set. In WWB type heat exchangers, tube insert is in a form of spiral coils. Heat exchanger operates in a continuous system at counter-flow system. Heat exchanger works in a vertical position with preservation of factor flow in a pipe space from up to down and in interpipe space from down to up.
