Heat Exchangers

Recuperator systems are heat exchangers that produce hot air by utilizing the energy of high-temperature waste flue gas generated in furnace systems, boiler systems and various processes. Recuperators various heating needs of facilities such as combustion air preheating and ambient heating are met and energy consumption is minimized. Compared to economizers, they have larger surface area and dimensions at the same heat capacity. They can be manufactured as finned tube and straight tube. Recuperator heat exchangers can be made from numerous materials steel, stainless steel and other special materials.

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.

This high pressure water jetting unit is extremely flexible due to its usage as a trailer. Three versions of the MK3 with operational pressure of up to 2500 – 3000 bar are available and is ideal for the removal of coating and concrete refurbishment, as well as for the separation and cutting of various materials. The easy to understand WOMATIC 4Control with operational status monitoring, pressurerpm regulation and pressureless circulation ensures high operational safety, low wear and tear, long service life, and last but not least, minimal fuel consumption.
