Transformer oil air coolers

Transformers with forced oil cooling systems require reliable, glandless transformer oil pumps. We offer a large range of such pumps, from which customers can choose a type that suits their specific requirements and ensures optimum operating conditions. Our oil circulation pumps are of simple, straightforward design and robust construction. Due to their compact size, the pumps can be easily integrated into the oil circuit. Four pump designs are available for different applications: Power Transformer Applications Inline and angle-type pumps with radial impellers and inline pumps with propeller-type impellers. Traction Transformer Applications Pumps with radial impellers for traction transformers in rail-mounted vehicles.

Our range of transformers oil water coolers can be supplied in different mounting variants. The standard water cooler version is designed for direct mounting to the transformer tank. In addition, our range of products comprises free-standing transformer oil coolers designed to customer specifications. The coolers in general are used for specific types of transformers, such as furnace transformers or rectifier transformers. A further application is machine transformer cooling at hydraulic power plants. Transformer oil water coolers are available in different design versions.

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.

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.
