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.

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.

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.

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.

Die neue Wärmetauscher-Platte NX350M

Product launch ・ May 11, 2020 read more Open In New icon

Sehr große Leistungen und eine hervorragende Wärmeübertragung selbst bei geringen Temperaturdifferenzen – das sind die Anforderungen an Wärmeübertrager im Kraftwerks- und Stahlbau, in der Fernwärme- und Fernkälteversorgung oder zur Kühlung von Rechenzentren. Die passende Platte für diese Aufgabe hat Kelvion entwickelt: die neue NX350M. Dank 350 mm Anschlussdurchmesser und Plattenabmessungen von ca. 1.000 mm Breite und 3.000 mm Höhe lassen sich mit ihr Apparate für Wärmeleistungen im zweistelligen Megawattbereich bauen. Dabei sorgen dünne, druckfeste Platten mit einer Prägetiefe von nur 2,4 mm sowie eine höchst turbulente Medienströmung für eine effiziente Wärmeübertragung. Das Optiwave-Design verstärkt diesen Effekt, indem es eine äußerst gleichmäßige Beströmung der gesamten Plattenbreite herbeiführt. Lesen Sie hier mehr:
