Direct and easy mounting to the transformer tank
Transformer Oil Water Coolers
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.
