Caloperm - Model Calodux -Plate Heat Exchanger

Calodux incorporates the advantages of plate heat exchangers and shell and tube heat exchangers. Calodux achieves a weight and construction volume reduction of up to 85% while maintaining the same heat exchange rate. Calodux allows high heat exchange performance even with extremely different flow rates on both sides. The short retention time in the unit makes it possible to handle delicate media.

Areas of application and uses of Calodux are:

• Power-to-X
• Chemical industry
• Refrigeration
• Oil and gas industry
• Offshore
• Plant construction
• Renewable energy
• Hydrogen

The operating conditions of your heat exchange process determine the plate thickness as well as the plate and shell material. Our standard plate material is 1.4404 (AISI 316L) with a thickness between 0.6 and 1.5 mm. We use nickel-based alloys or titanium for high temperatures, aggressive media or sea-water.

The heat exchange plates of the Calodux are joined together by a fully-automatic special welding process without any additional materials.
The thermodynamic and hydraulic characteristics of the Calodux are determined by plate corrugations, plate size and plate number. Our scope of delivery includes different plate corrugations for gases, water-like, highly viscous, and heavily soiled media, as well as for evaporation and condensation.

The profiled heat exchange plates provide for high heat exchange performance and the risk of fouling is much lower than in conventional shell and tube heat exchangers due to high turbulence even at low flow velocities.

In contrast to plate heat exchangers with gaskets, there are no maintenance costs or downtimes caused by the regular replacement of gaskets.

According to your demands Calodux is available in different designs:

1. Standard design:

• Welded shell with screwed side wall

2. Extreme operating conditions or aggressive media:

• Completely welded shell

3. Need for cleaning the plate packs and shells:

• Screwed shell with removal plate pack.

The Calodux heat exchanger stands out through its:

• High heat exchange performance even with small temperature approach
• compact dimensions
• light weight
• process-adapted flow path with different sized flows
• mechanical stability at differential pressures of up to 250 bar
• thermal stability at temperatures from -200 °C to +1050 °C

Calodux is designed and produced according to national, international, and maritime Regulations

The fully welded Caloperm 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 Caloperm heat exchanger.

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 Caloperm 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 ISO 9001 and PED 2014/68/EU.

Working principle of the Caloperm heat exchanger
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 apparatus 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 Caloperm heat exchanger can be delivered on the plate as well as on the shell side as one pass unit or more pass unit.
