Sondex Free Flow Plate

Sondex has developed a Real Free Flow Plate Heat Exchanger.

The plates have been designed without any metal contact between the plates and are specially designed for products, containing pulp and other fibrous material up to 2mm in diameter and a length of up to 5mm.

The flow is unimpeded and has a gap of up to 5mm, meaning that particles will not be caught in the plates. The Sondex Free Flow Plate Heat Exchanger can easily be maintained and cleaned without dismantling by cleaning-in-place (CIP).

The physical length of the PHE means that many applications can be solved in one pass solutions with all the connections on the fix end plate only.
