Heat exchanging has been used for many generations in the industrial sector. The heat exchangers have been directly included both in the primary processes of production and the secondary processes such as cooling and the recovery of heat from surplus heating.

The largest number of heat exchangers used are shell and tube and spiral heat exchangers. It is in fact a tradition that the industrial sector uses this type of heat exchanger.

Sondex can supply heat exchangers for most of the applications for which traditional heat exchangers are normally supplied, only on a more efficient and economic basis.

SONDEX supply plate heat exchangers with differential pressures of up to 30 kp/cm 2, and temperatures ranging from -30°C to +220°C.

SONDEX plates can be supplied with gaskets which can even cope with extremely harsh liquids.

In comparison to shell and tube and spiral heat exchangers the plate heat exchanger has a number of advantages as follows:
