Double tube heat exchangers (also known tube-in-tube) are designed whereby one tube is concentrically positioned within a larger tube. The double tube composition allows for unrestricted flow of product, making it the ideal heat exchanger for viscous products. The product flows through the inner tube and the service fluid flows through the surrounding shell.

Temperation of fluids Pillow plates are used everywhere where liquids must be temperated. In dependence of application the liquids can be cooled or heated. Cause of this wide range of applications pillow plates are used in the process industry, in the cooling industry and in a lot of other industries. Pillow plates are also know as heat exchanger plates, evaporator plates, cooling plates /sheets and thermo plates / sheets. Pillow plates as air-/water-heat exchanger Additionally to the temperation of liquids pillow plates are also used as air-/liquid heat exchangers. In case of polluted or wasted air and if there are high demands for cleaning, more and more pillow plates are used as air-/water-heat exchanger. The large exchange surface and the good possibilities for cleaning are important features for this type of heat exchanger.

Waste water treatment plants and surface waters have enormous energy potential. A sewage treatment plant, for example with 90 million litres of wastewater daily, reducing the wastewater temperature by using heat exchanger by around 1°C, generates a power of about 4.3 MW. The comparative potential for energy recovery from the surface water is even higher. Environmental aspect Induced by humans, water temperatures of the surface and streams have steadily increased, not least owing to the inflows from sewage water treatment. This has serious consequences on the flora and fauna. If heat is extracted from purified water in the sewage treatment plant or from surface waters and from streams, and water temperature is thereby reduced, this will have a positive effect on the entire ecological system. With KASAG heat exchanger systems, on the one hand, the energy requirement of the sewage treatment plant can be covered and, on the other, buildings in near vicinity can be heated or cooled.
