Heat exchanger

Heat Exchangers

Our line of Calorplast plastic heat exchangers is most suited for process air cooling under condensing conditions. Condensed water flows freely since the small plastic tubes have no fins and are extremely smooth.

The entire construction is made of plastic, both the heat exchanger elements and the matching casing. Materials applied are polypropylene and polyethylene. In the higher temperature and pressure range glass fibre reinforced polyester comes as an alternative for the casing.

Fouling is not an issue. In most cases the system is self cleaning by the continuous flow of condensed water. Free passage of water is guaranteed by absence of fins.
An optional integrated spraying system is available. Should cleaning be required, this is easily done using a high pressure water jet.

MilieuPartners supply fully integrated air cooling systems, complete with adiabatic water cooling towers or closed loop water/glycol systems.
