Sondex brazed plate heat exchangers can be utilised for heating and cooling of clean liquids and used as evaporator and condenser units.

Typical applications include;

• District heating / heating and ventilation
• Heating pumps / heat recovery units

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

Free flow plate heat exchangers can be used for fibrous and viscous food products. CIP cleaning is possible with plates and gaskets fully compliant with US 3A sanitary standard.

Semi welded plate are plates built up in a plate cassette. Two plates are laser welded together. This type of heat exchanger is specially designed for the refrigerating sector where aggressive media is applied.

Sonder safe plate is constructed where two plates are stamped together. The two plates form a pair of plates that allow possible leaks to be seen from the outside and prevent mixing of products. Applications are

• Milk and cream pasteurisation
• Sanitary water for food processing
• Water for medical injection/ultra pure

This heat exchanger works in the same way as ordinary tubular unit. However it is more efficient because plates have been used instead of tubes
