Transformer Oil Air Coolers

Service for Transformer Cooling Systems

Cleaning and upgrading fans on the transformer oil air cooler improves performance and efficiency, enabling the transformer to operate at maximum power with maximum cooling capacity, reliably and effectively for longer. While the fans are built for heavy duty, they can degrade due to continuous use and through accumulation of dirt and other pollutants. The Kelvion Service includes cleaning, maintenance, spare parts, as well as complete overhaul and upgrades to meet existing or new operational demands.

Upgrading the fans for better transformer performance

Over time the fans on a transformer oil air cooler will degrade, through extensive use and contamination. Should the fans fail, the transformer loses the maximum required cooling capacity, which means that the transformer cannot perform properly and loses maximum power. In some cases the equipment may need adapting on the air or oil side to meet new operational demands. Kelvion can modify fans from AC to EC, and upgrade fans to reduce noise. The Kelvion service also includes upgrading to hinged doors for easier access and cleaning.
