Particulars required for quotation

To enable Alfa Laval’s representative to make a specific quotation, enquiries should be accompanied by the following particulars:

  • Flow rates required

How it works

The heating surface consists of thin corrugated metal plates stacked on top of each other. Channels are formed between the plates and corner ports are arranged so that the two media flow through alternate channels, normally in full countercurrent flow. The media are kept in the unit by a brazed seal around the edge of the plates. The contact points of the plates are also brazed to withstand the pressure of the media handled.
