Shenshi | NEW Shell and Tube Heat Exchanger

 

Shenshi | BRIEF INTRODUCTION Shell and Tube Heat Exchanger


Shenshi's 65 & 130KW shell and tube are used for evaporators and condensers of hot and cold water units, modular units and other units. 7mm heat transfer tube upgrade, spiral baffle optimization, and multiple Shenshi's patented distributors are used in combination, with high heat exchange efficiency ; Shenshi's shell tube is designed and manufactured strictly in accordance with GB150, 151 standards. The fluorine side head is laser welded, with high pressure, no risk of leakage from traditional gaskets, the heat exchange tube is integrally formed, no splicing, no solder joints and water Contact, freeze resistance and strong reliability; Patented optimized design of the fluorine side head saves material costs, small hosing for small heat transfer tubes, high compactness, and small material consumption.

   

 

 

Shenshi | Shell and Tube Heat Exchanger Features
