Design
Sondex spiral heat exchanger is a circular heat exchanger with two spiral channels, each in one closed chamber ensuring that what comes in also comes out.

The flow of the two products is countercurrent which makes it possible to have a close temperature approach between the two media being treated in the heat exchanger.

In the same spiral heat exchanger the design makes it possible to run free flow on the one side and standard flow on the other side.
 

Easy access to the
heat transmission area.
It is essential to have easy access th the heat transmission area for maintenance and cleaning.
 
With a Sondex spiral heat exchanger this is a very easy task. Each side of the closed spirals can be accessed by opening the side frame of the heat exchanger, without any use of special tools.
