The Compabloc heat exchanger consists of a stack of corrugated plates that are welded together to form alternating hot and cold channels. The plates are made of stainless steel or other corrosion-resistant materials to ensure durability and long service life.

The heat transfer process in a Compabloc heat exchanger occurs through both conduction and convection. The corrugated plates create turbulence in the fluid flow, enhancing heat transfer by increasing the contact area between the fluid and the plate surface.

Design

The heart of the Compabloc is a stack of corrugated heattrans'er olates in 316L stainless steel, cr other high-gradematerial.The plates are leser welded (models CP30 and above) and form a corpact core. This core is then enclosed and suppcrted by four corner girders, top and bottom heads and four side panels.
These components are bolted together and can be quickly taken apart for inspection, service and cleaning.
The design can be configured in single or multi-pass arrangements in either co-current or counter-current operation, for liquid-to-liquid or two-phase duties.

Process Optimization
Because of the Compabloc's unique design concept the possibilities for process optimization and flexibility are limitless. The Compabloc can be designed with both single-pass or multi-pass configurations. For condensation, reboiling and liquid-to-liquid duties without temperature cross, the single-pass configuration is suitable with its total cross-flow.The large cross flow area and short flow path fit low-pressure conden-sing duties and allow very low pressure drops. A multi-pass configuration is suitable for duties with temperature cross and close temperature approaches. 

There are currently seven plate family models with heat transfer areas ranging from 0.7 to 840 m² per unit and each model is modularized with different numbers of plates to allow the best fits for any duty.

The design concept allows a different number of passes on the two circuits thereby enabling large differences in flow rates between the hot side and the cold side. The baffling can easily be re-arranged to suit a new duty should the flow rates or temperatures change. Close temperature approaches down to 3C (5.4F) can be achieved.
The Compabloc can be mounted vertically, for normal liquid-to-liquid duties, condensation with sub-cooling and gas cooling duties, or horizontally, for most condensation duties, reboiling or liquid-to-liquid duties where height is restricted.
