Kelvion introduces new transformer-oil air cooler

Published by
Hydrocarbon Engineering,

Kelvion has introduced a new transformer-oil air cooler that it claims to be 30 to 35% more economical in purchase than an individually designed premium cooler.

The Kelvion TOAC Smart functions without a tube sheet. Its heat exchange tubes are directly brazed into the collector manifold.

Various model choices allow adaptation of the new coolers to widely encountered applications. Depending on its size, the Kelvion TOAC Smart, for example, offers cooling duty of 100 kW for the smallest model, with one fan – and up to 600 kW for the largest version, with four fans.

The casing is made of sendzimir-galvanized carbon steel with high-quality powder coating. The tubes of the compact-finned heat exchanger are made of copper. The fins, depending on ambient conditions, can be made of copper, aluminium, or aluminium-magnesium alloy, or can be ordered with Blygold coating – which allows use in corrosion class C4. As a result, the Kelvion TOAC Smart represents a cost-effective solution for the cooling of transformer oil.
