Shell and tube heat exchangers are most commonly used in water-only heat exchange applications, like heating hot tubs, spas, and pools in conjunction with a boiler. These very efficient heat exchangers can also be used in cooling applications for cooling (or even heating) greenhouse irrigation water including plant nutrient solutions, and industrial process chilling/heating with chemicals as well as food products.
There are a number of advantages and disadvantages to using shell and tube heat exchangers, and it is very important to understand how they relate to your specific application. For instance, our units are made from corrosion resistant materials (316L grade stainless steel, or titanium) in order to provide the greatest long term performance and unit longevity, but obviously the more corrosive chemicals/materials you use with your heat exchanger will cause internal corrosion build-up, and may eventually lead to unit failure. So be sure not to exceed recommended levels of pH and plan for more frequent cleaning and maintenance in order to keep your unit operating with optimal efficiency.
