Design & Function

The Kelvion Machine Cooling plate fin oil (PF) cooler is especially designed to achieve excellent performance within the best compact design possible. A wide variety of shell sizes, shell lengths, different tube bundle inserts, and different materials enable us to select the most suitable compact cooler for each application. By standardizing this cooler type (modular build design), production lead times are short, and production procedures are transparent resulting in short delivery times, for our customers.

The PF cooler combines both advantages of using a tube bundle and plate finned heat exchanger technology. The bundle exists of a tube stack and special designed plate fins, which are built together as one rigid cooler bundle. Because of this construction, in combination with optimized tolerances, the bundle has a very high efficiency combined with a very compact size.

The PF cooler has high advantages in applications where oil has to be cooled off with another non-oil fluid. The surface on the shell side is enlarged because of the lower heat transfer value of most oils. The required cooling surface is realized by mounting closely placed plate fins around the tubes, which are built together as one rigid cooler bundle. The cylindrical execution ensures that vibrations and high-pressure pulses do not have any influence on the performance of the cooler. This non-welded compact cooler design is not sensitive for deformation.
