Transformer cooling

By maintaining a low temperature in the oil, a higher electro load is allowed in the transformer on a constant basis or during periods of peak demand. Alfa Laval offers a broad range of high quality cooling solutions for transformer oil with modern design air heat exchangers (OFAF) and double-wall plate heat exchangers (OFWF). The products are designed for maximum performance with a minimum footprint. Along with the heat exchanger, we also supply highly efficient and maintenance free transformer oil pumps.

AlfaBlue transformer oil coolers are light and compact, yet built to withstand tough conditions. For OFWF applications, Alfa Laval double wall plate heat exchangers provide the double safety you need.

Rectifier cooling

Alfa Laval offers various solutions for liquid cooled rectifiers: Air, plate and fusion bonded heat exchangers. The fusion bonded AlfaNova in 100 % stainless steel is particularly well suited for copper free environments and when space is limited and compactness is required.

Frequency converter cooling (AC drives)

Alfa Laval has extensive experience and know-how when it comes to cooling of drives. Compactness of modern frequency converters is vital. With integrated Alfa Laval heat exchangers it’s possible to combine compactness with high cooling efficiency.  

The compact fusion-bonded AlfaNova in 100% stainless steel is particularly well suited for pure water when space is limited.
