How it works

The Compabloc Free Flow comes in two versions. At its core is a stack of corrugated heat transfer plates made of stainless steel or alloy C22 that are alternately welded to form channels. The vapour and the cooling medium flow through alternate channels, causing the vapour to condense on the cold plates. The wide free-flow channel results in a very low pressure drop, making it ideal for deep vacuum condensing duties. On the coolant side, baffles direct the cooling media back and forth through the channels to increase turbulence and thermal efficiency.

 

The complete plate pack slides inside a steel frame bolted to pressure-retaining heads. Four removable panels contain the inlet and outlet connections and give easy access to all product-wetted surfaces.

Single-pass condenser

 

This version is suitable when the vapour contains small amounts of inert gases. Vapour enters through the big inlet on the top panel and condenses on the plates. The condensate exits through the sloped, drainable bottom panel.

Two-pass condenser

Two-pass condenser

The two pass version can be used when the vapour contains a larger portion of inert gases. Main condensation takes place in the first pass where the condensable part of the vapour condenses on the plates before exiting through the sloped, drainable bottom panel.

The non-condensable vapours go through the second pass where they are sub-cooled to maximize condensation. Turbulence in the second pass helps to eliminate mist, and vacuum is easily drawn from the outlet of the second pass. With a two-pass condenser there is no need for an additional vapour separator, since separation takes place in the unit.
