The fully welded Calopyx heat exchanger combines the best features of plate heat exchangers and shell & tube heat exchangers.
The heat exchange area consists of a pack of profiled stainless steel plates alternately welded together at the outer and inner diameter. Fitted with end tubes the plate pack is brought in position inside the shell, all the support is assembled and finally all components are welded together to the complete gasket free Calopyx heat exchanger.
 
Calopyx plate package

Like traditional plate heat exchangers the profiled
heat transfer area stands for

  • optimal thermal performance
  • low fouling
  • reduction in footprint
  • close temperature approach

And as in the shell & tube technology the units are

  • usable for high operating pressures
  • feasible to very high and very low temperatures
  • gasket free
 
Each Calopyx plate heat exchanger is designed and manufactured for your specific operating conditions.
The heat exchanger plates are welded together with a robot welding system. Non destructive test procedures during the manufacturing ensure unchanged high quality of the plate packs. The production process is controlled by a quality system according to DIN EN ISO 9001.

Working principle of the Calopyx

The plates are welded together alternately on the outer diameter and in the connection holes. Thereby a plate pack is formed with alternating channels for hot and cold media. The welded connection holes form the inner channel. At its end, this channel is fitted to the connecting pipe leading out of the shell. The shell channel goes straight through the plate pack. After assembling all components, the CP is totally welded together. This results in a gas tight unit, being able to handle high temperatures and high pressures as well as aggressive media on both sides. The Calopyx heat exchanger can be delivered on the plate as well as on the shell side as one pass unit or more pass unit.
