Kelvion air dryers and air preheaters Heat exchange with air “by Kelvion”: sustainable, versatile, customize

GEA Heat Exchangers has changed: another new standalone company has been created out of the former Heat Exchanger Division of the GEA Group AG. The name Kelvion is new, but we continue as global experts in heat exchange. As always, we remain committed to earning your trust. You'll still recognize us. We continue to develop our products, manufacture them with precision and distribute globally. We con- tinue to offer one of the world's largest heat exchanger product portfolios: Plate heat exchangers, shell & tube heat exchangers, finned tube heat exchangers, modular cooling towers and...

Combined product and application expertise Wherever heat exchange is required within industrial production processes, Kelvion engineers regulate it all to a precise temperature. Oil, gas and chemicals, steel plants and power stations, from waste incineration to drying equipment – Kelvion has one of the most comprehensive, if not the most comprehensive heat exchanger portfolio Pressure vessel regulations 97/23/EC; AD 2000 rules The product range comprises all designs of air dryers and air preheaters for all ASME U-Stamp conceivable applications. Whether it’s simple components or complex...

Air heaters and air dryers: the all-rounders Air dryers Air dryers are available in different materials, customized for every application: Heavy industrial loadings or high temperatures make no difference to air dryers made of galvanized steel. They are manufactured completely from steel to form a welded unit. The elliptical finned tubes are hot-dip galvanized. Frame and headers are protected against corrosion by zinc-dust primer and an epoxy aluminium finishing paint. It goes without saying that the complete heat exchanger unit is also available as a version galvanized in a dipping bath....

Heat exchangers using the single-tube design can be equipped with either finned or plain tubes. Elliptical finned tubes are a Kelvion speciality. The elliptical core tube has good aerodynamic properties because it reduces the slipstream behind the tube. Thus the cooling surface is increased, pressure loss and soiling decrease and the noise level drops. Air preheaters Air preheaters are heat exchangers for heating and evaporation, for cooling and condensing Benefits of the elliptic finned tube: aerodynamically favourable and for heat recovery. Many decades of experience in designing and...

Variants for every demand U-shape side panel Sectional edge Header profile - Tube tiozzie Fixed-side tube sheet Separating plate Header plate Designs are governed by the customer's requests and depend especially on the pressure level prevailing in the system. Style E is suited for heat exchangers that are not subject to an acceptance test. The heating and cooling surfaces consist of hot-dip galvanized finned tubes. Heating or cooling medium connections realised as butt welding ends are standard with this style. However, welding-neck flanges can also be fitted upon request. The air...

Special designs Style D is designed for higher pressure When is comes to special designs, Kelvion Special designs: ratings and meets the relevant acceptance customers have an extensive choice welded tubes, tubes and headers can criteria. Welding-neck flanges of the regarding header and tube design required pressure rating are always (rolled-in or welded) as well as materials provided for heating and cooling medium Style R: removable header cover, Style S: removable header, rolled-in or welded tubes, header can be coated connections. Heating and cooling surfaces internally, tubes and headers...

Customized design Pitch of elliptical finned tubes The fins punched out of the sheet metal coil are attached to the elliptical core tube. Hot-dip galvanization ensures a good metallic joint. The heat exchanged depends on the pitch of the fins – between 2.1 and 6 millimetres – and on punchings taking the shape of spacers or turbulators. Shape of fins on round tubes When using round core tubes, the fin shape and material determine the heat exchanged and the field of application. The elliptical finned tubes have a wide Here the steel strip is wrapped around the In this process, the finned...

The joint between the fins and the core tube has major influence on the heat exchanged. Fins made of aluminium or galvanized in a dipping bath are mostly used with steel or stainless steel core tubes. Aluminium can be shaped easily and is also a particularly good heat conductor. Fins made of steel make very robust and sturdy tubes that are suitable for highpressure cleaning. An L-shaped fin strip is wrapped around the Finned tubes of this type are rolled from The G Fin type is a high-fin spiral finned core tube like a helix. The manufacturing a pure aluminium hollow blank tube slid tube....

Experience + wide system range = wide range of applications Kelvion supplies heat exchangers for numerous branches of industry – for heating and evaporating, for cooling and condensing and for heat recovery. Almost a century of experience in designing and manufacturing and almost a hundred different systems ensure that our engineers can realize solutions for the most varied tasks:

Air coolers and air heaters for chemical and process engineering Air heaters for drying engineering, e.g. stenter dryers with integrated, galvanized steel finned tube heat exchanger or chemicals drying plants using stainless steel heat exchangers Air preheaters for boiler plants, e.g. in power stations and waste incineration plants Kelvion Econorm for energy savings and heat recovery Economizers for steam, oil and hot water production Steam and water recoolers Waste gas cooling following thermal incineration Air coolers for wind tunnels in the automotive industry Production of food and...
