The perfect choice for heating commercial and public swimming pools with a domestic boiler.
Typical Heat Transfer from a boiler: 300 kW
The Bowman GL140-3708-2 is an efficient shell and tube heat exchanger which is suitable for heating swimming pools up to 478 m³ via a boiler heat source. The cast end covers are finished in ‘C’ coat, an advanced technology coating, which is highly corrosion-resistant for durability and the unit is available with either a titanium or cupro-nickel tube core.
As the graphs and table above illustrate, providing the right water flow volume is vital to the performance of the heat exchanger. If the flow rate of either the hot water supply, or the pool water circuit is too low, the heat exchanger will not perform at its designed efficiency and will be unable to transfer all the available heat energy in to the pool water.

Refer to the following diagram for how to install the heat exchanger in the pool system. The heat exchanger can be mounted either horizontally or vertically as per the schematic.
