Shell and Tube Heat Exchanger
Shell and tube heat exchanger is the most typical dividing wall type heat exchanger, its application in the industry has a long history, and it still occupies a dominant position in all heat exchangers.
A shell and tube heat exchanger consists of a shell (a large pressure vessel) with a bundle of tubes inside it. One fluid runs through the tubes, and another fluid flows over the tubes (through the shell) to transfer heat between the two fluids. The wall of the tube bundle is the heat transfer surface.
An essential component for swimming pool heating systems and other water heating applications, Swimming Pool Heat Exchangers are designed to maximize water heating efficiency and save money and energy.
Note:
It is recommended maximum chloride concentration in fresh/clear water inside the heat exchanger under 140℉ is considered to be: 300 mg/L. When water temperature increases, the maximum chloride concentration should decrease.
Above the recommended concentration of chloride and/or directly use a chlorinator might induce pitting of 316L stainless steels overtime. Titanium pool heat exchangers are recommended for environments with high chloride concentration or saltwater systems.

Working Theory
Two fluids of different starting temperatures flow through the heat exchanger. One flows through the tubes (the tube side), and the other flows outside the tubes but inside the shell (the shell side). Heat is transferred from one fluid to the other through the tube walls, either from the tube side to the shell side or vice versa.
Spiral-corrugated Tube Design
Our product has an innovative spiral-twisted, corrugated tube design that is engineered to maximize solar or boiler energy, increasing the overall thermal efficiency of the system. The tube's design also ensures high velocities inside the unit, making this heat exchanger a very reliable, efficient, and cost-effective way to transfer heat indirectly between any hot water circuit, steam circuit, and pool or spa application.
About the Heat Excahnger
A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold liquid. Heat exchangers are general-purpose equipment in chemical, petroleum, power, food, and many other industrial sectors and play an important role in production.
There are many types of heat exchangers, but according to the principle and method of heat exchange between cold and hot fluids, they can be divided into partition type, hybrid type, and regenerative type. The partition wall heat exchanger is the most widely used among the three types of heat exchangers.
According to the shape and structure of the heat transfer surface, it can be divided into the shell and tube heat exchanger and plate heat exchanger.
Fluid Layout Instructions
In shell and tube heat exchangers, there is a potential for a tube to rupture and for high pressure (HP) fluid to enter and over-pressurize the heat exchanger's low pressure (LP) side. To avoid risk to people and financial loss, the usual configuration of exchangers is for the HP fluid to be in the tubes and LP water, cooling, or heating media to be on the shell side.
