Air-cooled heat exchangers

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...

Your requirements define our solutions Wherever cooling processes are required within your industrial production facilities, we regulate it all to a precise temperature. Oil, gas and chemicals, steelworks and power stations, from paper to textiles – Kelvion provides you with individual solutions throughout the world: Air-cooled heat exchangers and condensers Heat exchangers with galvanized finned tubes Our portfolio includes all air cooler designs for all applications, starting with simple components and ending with complex process engineering. Your benefits include: manufacturing quality,...

One feature of our quality: Your satisfaction Kelvion air coolers often have to prove their worth under extreme conditions and guarantee reliable operation. This is why a team of experts including engineers, welding experts and other quality inspectors scrutinizes every apparatus and every single component very precisely. This procedure ensures that we meet all quality requirements. And we achieve this in complete control as numerous certifications demonstrate.These certifications comprise both the safety requirements according to international pressure vessel regulations PED 97/23/EG,...

Kelvion air-cooled heat exchangers – always in the right place Wherever cooling is required in production processes – we offer you the optimum air cooler for your application: Refineries Petrochemistry Steelworks, steel industry Gas facilities Power stations Other industrial cooling applications

Inspired by the efficiency concept. Designed for maximum performance. Finned tube bundle Heating coils Pulley Drive belt Supporting structure Air cooler bank The air cooler bank essentially consists of finned tube bundles, fan rings, axial fans with suitable drive units and a supporting structure. It can be equipped individually with maintenance platforms, louvers and other equipment as requested by the customer. Kelvion constantly underpins its technological leadership with new product developments. This includes special high-performance finned tubes with optimized material and design,...

Depending on your specific requirement: Kelvion air coolers are oriented towards the respective process requirements and the particular features of the location. Regardless of design characteristics, unhindered air feeding and discharge must be ensured. Where space is at a premium, roof structures are used. Header (outlet) Vent/ drain Tube sheet (fixed side) Header (inlet) Guide bolt Cover plate Side wall Lug Tube sheet (floating side) Finned tubes Finned tube bundle A finned tube bundle consists of finned tubes (in special cases unfinned tubes are also possible), the headers for...

Finned tubes in detail Groovy Fin tube type Extruded tube type Product benefits: Product benefits: Product benefits: • new patented high-performance finned • compared with similar fins, extruded • large contact area between tube and fins tube, pioneering technology • resists high loads, both thermally and mechanically • extremely dimensionally stable • hardly any maintenance is required – maximum reliability • optimised surface, less fans – clearly reduced energy consumption • less space required, less cabling – less installation effort fins consist of more than 40% more well protected...

The economic profitability of an air-cooled heat exchanger depends on the capacity of the finned tubes. The capacity results from the transfer of the maximum heat exchanged in the smallest possible space while keeping thermodynamic losses on the air side low. FE/KE/AE tube types PI/HI tube type Product benefits: Product benefits: Product benefits: • the elliptic shape enables excellent • special design for high pressure ratings • thermodynamic properties and air-side thermodynamic properties • less vortex formation results in reduced pressure loss on the air side • additional baffle...

Cover plate header with through bolts Cover plate header with stud bolts Welded header (D type) This header version has a removable cover In this version, the nozzles are arranged at The inexpensive header design is mainly to enable easy inspection and cleaning of used for clean products or a high vacuum. the inner tube walls. For inspections it is can remove the cover plate without The tubes are welded into tube sheets, and generally sufficient to remove only a dismantling any tubes. The cover plates are D type headers with the required manifold because this already offers a also available...

The specific feature: Kelvion headers are available in all material types. They can be used in all pressure and temperature ranges and therefore predestined for various media and marginal conditions. Plug-type header High-pressure header with return segments High-pressure header with welded return bends Here the tubes are usually rolled into the A threaded plug with a soft iron seal is This high-pressure header, just as the variant plug headers; in special cases, they are provided opposite every tube. This plug can with the return segments, is perfectly suited directly welded into the tube...

Direct drive Belt drive for forced draft configuration The fan is fitted directly to the motor shaft, using a flange. Fan This version uses pulleys for reducing the motor speed to the required speed and motor speed are identical. Belt drive for induced draft configuration Gearbox drive When waste air temperatures are low, the motor can also be This drive includes a fan joined directly to the output shaft of the installed above the bundle. gearbox motor. Different versions, one common feature: Kelvion air cooler fan drives are convincing with their high degree of reliability and their low...
