Kelvion PHE Systems

During compression in the turbocharger, the combustion air is heated to more than 200°C. Before entering the engine, the air needs to be cooled down within the CAC.

For more than 50 years, Kelvion has led the way in developing and manufacturing charge air coolers. Designed for diesel and gas engines, they have a worldwide reputation for excellent performance and reliability. Working in close collaboration with leading engine manufacturers, we develop dedicated solutions tailored to customer requirements.

Kelvion shell & tube heat exchangers and gasketed plate heat exchangers play an important role in cooling down the gearbox – used to change the rotation speed of the propeller shaft – and thrusters, which are used for maneuverability.

A freshwater circulation system absorbs heat from the engine. This high temperature (HT) water, known as jacket water, is subsequently cooled by a low temperature (LT) water circuit. A third circuit, containing seawater, is used to cool the LT water. We offer two solutions that help to ensure optimal engine performance: Our state-of-the-art plate heat exchangers have been used successfully for cooling and heating all types of fluids. Made from the highest quality materials, they ensure maximum heat transfer, high performance, and long service life. Our plate heat exchangers are particularly recommended for cooling jacket water on large ships. We recommend the box cooler for small and medium-sized vessels. It is virtually maintenance-free and can be customized for all operating conditions. The box cooler is fitted in the sea chest on the side of the vessel, saving space in the engine room. This solution offers the additional advantage of eliminating the need for a seawater circuit.

Marine diesel two-stroke and four-stroke reciprocating engines have to be lubricated with oil to ensure the smooth movement of the piston and crankshaft in the bearings, reducing to a minimum the friction which interferes with engine efficiency and damages components. To prevent oil overheating, heat exchange technology is required. Where the oil cooler is incorporated into the engine, Kelvion can supply the core components for a shell and tube heat exchanger, which is then mounted on the engine block. In addition, our gasketed plate heat exchangers and shell & tube heat exchangers have a proven track record in helping diesel engines to maximize performance. Kelvion compact, highly efficient plate heat exchangers guarantee the ideal oil inlet temperature for the lubricating oil circulation system, thereby minimizing the effects of friction and wear on the engine. With its revolutionary plate fin technology, the shell and tube heat exchanger is specially designed to achieve the highest performance, within the most compact format. A wide variety of shell sizes, tube bundle inserts, and materials enables Kelvion to select the best cooling configuration for each application.

The central cooling system onboard a marine vessel is essential for taking the heat out of the freshwater and oil streams that circulate through the machinery within the engine room. As seawater is generally used as the cooling medium, it places stringent demands for corrosion-resistant materials to be used in all products that come into contact with it.

Kelvion advanced plate heat exchangers and box coolers are optimally designed for maritime applications and made from the highest quality materials. They provide efficient, powerful cooling of liquids, reliably and over a long service life. Box coolers also provide efficient central cooling on smaller vessels.

A marine air compressor supplies high-pressurized air for starting the main and auxiliary engines. To ensure that the bearings are not damaged by friction, they are supplied with lubricating oil to keep them running smoothly. During operation, the lube oil heats up and needs to be cooled.

The shell and tube oil cooler is fitted with our innovative plate fin technology and has been proven time and time again as an efficient and cost-effective solution. Because of the large heat exchange surface around the tubes, the cooler is very compact and therefore easy to service. What’s more, it can be produced in different configurations to suit customer requirements.

The generator is the lifeline that supports all the functions onboard the ship and keeping it running round-the-clock requires special care, attention, and maintenance. Cooling technology has an essential part to play in supporting the optimum operation.

Kelvion finned systems, which are individually developed according to customer specifications, improve the heat transfer in tube systems. This means that they require less material to achieve optimum performance – an important consideration for ships that have strict rules governing the size of installations.

Based on a recently developed fin tube system, this patented design has the capability to cool gases down from more than 700°C to 50° C. Kelvion developed the technology in close collaboration with their customers, ensuring that the recirculation exhaust gas is mixed at the lowest possible temperature with the combustion air to reduce NOx emissions most effectively. Kelvion compact, service-friendly, recirculation coolers are customized for each diesel engine manufacturer and made with corrosion-resistant materials.

Plate heat exchangers from Kelvion have proved highly efficient at cooling and heating fluids of all types. Made from the highest quality materials, they provide maximum, reliable heat transfer and long service life.

Over the last 40 years, Kelvion has forged long-lasting relationships with turbine makers, main EPC contractors, engineering companies, and plant end users. Kelvion surface condensers have the reliable and efficient performance that is essential in a steam turbine cycle. They create customized solutions to meet our customers’ specific requirements. All our condensers are manufactured in a range of materials to suit the quality and nature of the cooling water.
