KELVION GERMANY GMBH

Air cooled condensers are engineered to project products with several architecture and customized design. The air cooled condenser belongs to the dry cooling systems. In direct dry cooling, steam from the steam turbine passes through air-cooled fin tubes. The condensate is not in contact with the cooling air.

Our fully-welded plate heat exchangers make a convincing case due to their minimal size, outstanding thermal transfer coefficients and comparatively minimal investment costs. They are particularly robust and require only minimal cleaning and servicing. Their design advantages come into play especially in areas, in which, in addition to the output, load capacity is also a requirement.

This new addition to our product line is a compact heat exchanger made from high-alloyed stainless steel and can handle temperatures up to 550°C. Its compact and modular design makes it extremely versatile and easy to service. Our exhaust gas heat exchanger is designed to recover heat from exhaust gas produced for example by combustion engines used in combined heat and power plants. The heat exchanger transfers the heat from the exhaust gas to a liquid (water or water-glycol solutions). When heated up, this liquid can be used in central heating systems; for preheating air in the combustion chambers of furnaces and turbines; to dry coal, pulp, wood and other materials as well as for generating electricity with a Rankine process.

A Box Cooler is a vessel water cooling system. It comprises a U-tube bundle that is fitted in the sea chest on the side of a vessel, saving space in the engine room. The sea chest is equipped with inlet and outlet grids. Cooling sea water enters through the inlet grid and flows along the U-tube bundle to the outlet grid, thus cooling the water inside the tubes. The cooling effect is achieved by the forced circulation of sea water when the vessel is moving or by natural convection when it is stationary. Box coolers can be used for a wide variety of temperature-reducing duties on a vessel, from cooling the main engines, auxiliary engines and bow thrusters to air conditioning and hydraulic systems. Kelvion Box Coolers are ideal for small and medium sized vessels, including for example: tugboats, barges, fishing boats, carriers, dredgers, supply vessels, ferries, ice breakers, cargo freighters, tankers and reefers.

Closed circuit coolers are designed according to customers' requirements and assure exact compliance with their performance specifications. Our finned systems enhance heat exchange to the tube system and allow low material usage without performance loss. Tooling flexibility allows each system to be adjusted with its tube banks side by side or on top of each other, offers options of meeting extreme customer demands. Our many offical approvals and certifications allow us to design and manufacture closed circuit coolers for many and various applications.

Most of the industrial processes require heat exchanger equipment and miscellaneous pressure vessels. The great variety of industrial processes and applications require a wide capability of performing complex thermal and mechanical design as well as the capacity and experience in manufacturing heavy equipment made of special materials to withstand demanding operating conditions. Shell & Tube equipment is a very wide category of products that are suited for very simple storage tanks for low pressure and low temperature applications to complex reactors for high demanding applications. The most common processes in the Oil & Gas, Petrochemical & Chemical, Food & Beverages and Heavy & Light Industry require a significant number of equipment to exchange heat or to storage different fluids or components. For all of them we have a specific solution.

Since the invention of the Desublimator in 1954 we have delivered about 1500 Desublimators worldwide. We have continuously developed the mechanical as well as the process design of the Desublimators. In particular, we have adapted the special designed fin tube system composed of rectangular fins to the newest requirement of the PA process, mainly to the increasing feedstock loading of the air. The most important process key figures of the newest switch condensers are: gas flow: max. 40,000 Nm³/h capacity: max. 10,000 kg PA/cycle efficiency: min. 99.5 % oX-loading: 100 g/(Nm³ air) and higher Feedstock: o-xylene, naphthalene or mixed feed

Air preheater are heat exchangers for heating and evaporation, for cooling and condensing and for heat recovery. Many decades of experience in designing and manufacturing have made us a leading supplier of heat exchangers for cooling and heating of gaseous and liquid media. The wide range of available plain and finned tube systems is certainly an important aspect of our market success. Finned-tube heat exchangers can be made from numerous materials: steel, stainless steel, copper/aluminum, aluminum and other special materials. Plain-tube heat exchangers are used mostly where a fluid present around the tubes is so polluted that finned tubes can no longer be used. Plain tubes can be configured in different ways either next to one another or serially. Steel and stainless steel versions as well as a hairpin design are also possible.

Our range of transformer oil air coolers for forced oil cooling systems can be supplied in different mounting variants. The standard air cooler version is designed for direct mounting on the transformer tank. In addition, our range of products comprises free-standing transformer oil coolers designed to customer specifications. Transformer oil air coolers are available in different design versions.

K°Bond is our new diffusion bonded heat exchanger and the right choice for applications where highest temperatures and pressures have to be processed on restricted space, like offshore applications and floating units. Explore how your application can benefit from our new Kelvion K°Bond. K°Bond, Kelvion’s diffusion bonded heat exchanger, is ideal for applications involving extreme process temperatures and pressures. Combining design with welding expertise, K°Bond withstands pressures up to 1,000 bar and temperatures from cryogenic —200 to 600 °C. Significant savings in weight and footprint compared to common heat exchanger solutions. K°Bond with its diffusion bonding technology is perhaps one of the most significant and game-changing solutions for projects with restricted space – May it be for offshore plants (e. g. as high pressure vaporizer) and reliquefaction on floating units.
