Transformer Cooling System
Our range of transformer cooling systems can be supplied in different mounting variants. The standard air cooler version is designed for direct mounting on the transformer tank. In addition, our range of products comprises free-standing transformer oil coolers designed to customer specifications.
TRANSFORMER OIL PUMPS THAT SUITS YOUR REQUIREMENTS
Transformers with forced oil cooling systems require reliable, glandless transformer oil pumps. We offer a large range of such pumps, from which customers can choose a type that suits their specific requirements and ensures optimum operating conditions.
Our oil circulation pumps are of simple, straightforward design and robust construction. Due to their compact size, the pumps can be easily integrated into the oil circuit.
Four pump designs are available for different applications:
Power Transformer Applications
Online and angle-type pumps with radial impellers and inline pumps with propeller-type impellers.
Traction Transformer Applications
Pumps with radial impellers for traction transformers in rail-mounted vehicles.
OIL COOLING SYSTEM: TRANSFORMER OIL AIR COOLERS IN DIFFERENT MOUNTING VARIANTS

TRANSFORMER OIL WATER COOLERS DIRECT AND EASY MOUNTING TO THE TRANSFORMER TANK
Our range of transformers oil water coolers can be supplied in different mounting variants. The standard water cooler version is designed for direct mounting to the transformer tank. In addition, our range of products comprises free-standing transformer oil coolers designed to customer specifications. The coolers in general are used for specific types of transformers, such as furnace transformers or rectifier transformers. A further application is machine transformer cooling at hydraulic power plants
Unlike tube bundles of single-wall design, double-tube bundles are provided with two tube sheets at each end. If a tube wall shows a leak, the product flows through fine ducts arranged between the double tubes into the leakage collection space and triggers a check command. However, the second remaining undamaged tube keeps the fluids separated. The plant operator may continue to run the heat exchanger until the next scheduled maintenance, thus avoiding cost-intensive shutdown times. We have been supplying double-tube coolers for more than thirty years. Today, double-tube safety heat exchangers are state-of-the-art for transformer oil water coolers.
