Generator and transformer oil cooling

Successful conversion of thermal energy into electricity requires safe, reliable and efficient turbine island systems. At the same time, it is critical to ensure safety, conversion efficiency and regulatory compliance while generating maximum output. Alfa Laval has broad expertise and a wide range of reliable equipment and services that help increase plant safety, efficiency and uptime.

On the pulse of generator and transformer oil cooling

Converting mechanical energy into electrical power depends largely upon the generator. It is critical to prevent generator overheating and breakdown through efficient removal of the heat that results from conversion losses.

Our plate and frame solutions provide efficient cooling of the generator. The water transfers the heat from the generator to the intermediate closed loop cooling system. Alfa Laval has a broad portfolio of oil coolers that help maximize plant output.

Double wall industrial GPHE

The Alfa Laval double-wall gasketed plate heat exchanger provides added security to prevent cross-contamination of the oil with water. To maintain environmental safety, a double-wall plate heat exchanger is an excellent choice for direct cooling of transformer oil using cooling water from an open cooling system.

Air-cooled heat exchangers

For direct cooling when using a gasketed plate heat exchanger is not an option, Alfa Laval offers an extensive range of air cooled heat exchangers

These Alfa Laval finned coil air heat exchangers  are designed to optimize the exchange of thermal energy between air and a refrigerant or fluid. The ‘heart’ of our air heat exchangers is the finned coil built from a circuit of interconnected tube serpentines and fins, which increase the heat exchange surface area.
