TEPL MAKE DOUBLE TUBE COOLER

Our Double wall type coolers are designed and manufactured with special care where transformer oil cooling is a critical application. Because we understand that failure in transformer due to cooler leakage may lead to heavy financial losses.

Unlike single tube coolers, this execution of the tube bundle requires double tubes. This special safety design prevents the chances of water and oil mixing in heat exchanger and also the cooling water pressure is not limited by oil pressure. Also the processes need not to be terminated immediately after the failure. Thus keeping the transformer in service. In case of leakage, water or oil is led into the chamber between tubes and the tube plates, therefore the double tube system always prevents water and oil from mixing.The double tube design is the most valid solution to protect the transformer, especially when, using sea or industrial water, and where the site maintenance is not easy. In case of leakage an alarm is provided to a leakage detector provided at the collecting box fitted to the cooler.
