SONDEX advantages

Gasket Plate Design  

By means of technological innovation SONDEX has developed and designed a new generation of plate heat exchangers. With the big range of plate heat exchangers SONDEX has got the optimal technical solution for any possible task, with connection sizes from Ø15 - Ø500 mm covering a liquid flow of 50 l/hour - 2000 m3/hour. The construction of the inlet part makes a perfect distribution of the liquids across the heating surface. The inlet part is increased and supplied with grooves preventing "dead spots" which may cause the growth of bacteria in the plate heat exchanger. The inlet with grooves secures a strong inlet part with a minimum of contact points.

Brazed Plates    

Contrary to the traditional plate heat exchanger the brazed plate heat exchanger does not contain rubber gaskets and can thus operate continuously at the temperatures from minus 180°C up to plus 200°C. The operating pressure can be as high as 30 bars.

Semi Welded Plates  

Semi welded plates are built up in plate cassettes. A plate cassette is 2 plates welded together by means of laser welding. The advantage by this construction is on the one side a welded plate channel and on the other side a traditional plate channel with gaskets making assembling and cleaning of this side easier. On the welded side there are two specially produced corner whole gaskets creating the tightening between the two cassettes. Thus the gasket is reduced to a minimum on the welded side.

Free Flow Plates

Free Flow plates are designed for liquids containing fibres or other particles which may clog up a traditional plate heat exchanger. SONDEX Free Flow plates are designed without metal contact between the plates in the liquid area giving a high turbulence and thus a high heat transmission coefficient and especially a long power time.

Sonder Safe Plates  

The SONDEX Sonder Safe system consists of two thin flow plates stamped together. The two plates form a pair of plates which allows possible leaks to be seen from outside between the two plates. This prevents a mixing of the products and warns about internal leaks.

Plate and Shell Heat Exchanger  

This heat exchanger works in the same way as an ordinary tubular unit, however, it is more efficient because plates have been used instead of tubes. The plates are laser/TIG welded together to form a plate pack, which is then mounted inside a traditional cylindrical shell. The heat exchanger is produced as an all welded exchanger or with flanges. This makes manual cleaning possible. Pressure rating: PN16/PN25. Max temp.: Up to 250 °C.
