Shell and Tube Evaporator Structural Features:

The shell-and-tube evaporator has a structure similar to that of a shell-and-tube condenser, with the difference being that the refrigerant flows inside the tubes while the secondary coolant flows inside the shell. Our evaporators are manufactured using precision lathe machines (CNC and copper tube thread machines) with high-quality, well-known brand purple copper tube materials. They are highly efficient and energy-saving, with a compact appearance.

Whether it's a shell-and-tube condenser or an evaporator, their main manufacturing process and materials used are the same. Both utilize a large steel cylinder, inside of which are welded varying numbers of low-fin copper tubes (as required) to form two separate channels. Over time, due to material fatigue or inherent material quality issues, some low-fin copper tubes may develop cracks and leak; similarly, the welding of the low-fin copper tubes to the shell tube plates may also result in cracks or porosity due to welding material fatigue or welding quality issues, leading to leakage.
