Bowman Shell and Tube Heat Exchangers
Robust, Versatile, and Highly Efficient Range of Heat Exchangers for Pools and Spas of All Sizes
Bowman shell and tube heat exchangers are designed and built in England for use within swimming pool and spa heating systems via boiler heating or renewable heat sources, with Valutech acting as the official distributor of Bowman shell and tube products in North America. Bowman units offer reductions in CO2 emissions relative to conventional pool heat exchangers, and removable tube stacks allow for maintainability over the course of the unit’s lifetime. We also provide a range of models specifically designed for use with fluids heated by renewable sources, such as solar and geothermal, as well as condensing boiler and heat pump systems.
All Bowman units are available in the following tube materials:
- Titanium
- SS 316
- Cupronickel
