U Tube Type Heat Exchanger For The Petroleum And Chemical Equipments

The u tube type heat exchanger is composed of a shell housing a bundle of tubes. Heat transfer occurs between two fluids, with one flowing through the tubes and the other passing through the shell. This versatile heat exchanger finds extensive application in various industries such as chemical, power generation, HVAC and refrigeration, oil and gas, compressor cooling, marine, pulp and paper, metals and mining, among others.

Our heat exchangers are highly customizable to meet your specific requirements. Each unit's specifications can be tailored to your needs, ensuring optimal performance and efficiency. We take pride in providing tailored configurations that precisely match your application demands.
