The Basco^® extended surface shell and tube heat exchanger is a type of heat exchanger where fins are added, with a unique patented compact design. It can efficiently cool down under the low pressure drop condition, effectively reducing the energy consumption. Meanwhile, fins are added to enhance the heat exchange effect, which eliminates the difficulty in realization of efficient heat exchange in the compact space, ensuring that the product fully meets the requirements for use in industrial scenarios where a high heat exchange efficiency needs to be reached in a limited space.
