PK190-5119-3 – 1170 kW

The perfect choice for heating the largest commercial and public swimming pools with a domestic boiler.

Typical Heat Transfer from a boiler: 1170 kW

The Bowman PK190-5119-3 is a highly efficient shell and tube heat exchanger, which is designed for heating the largest size commercial swimming pools, up to 1,680 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.

Product Benefits

  • Performance – heats pools fast, reducing energy costs
  • Proven – designed for the largest commercial leisure or sports pools
  • Durability – salt water and mineral rich fresh water compatible
  • Simple to maintain – easy disassembly for cleaning
  • Titanium models – full 10 year warranty on titanium models


Simple to Maintain

The modular design means that end covers on all models are easily removable, enabling the tube stack to be easily extracted from the outer ‘shell’ ensuring all maintenance requirements are simple and straightforward.

Energy Saving

The faster a pool gets to the required temperature, the lower the energy costs! Bowman units heat pools up to three times faster and the result is reduced energy costs and improved pool availability.

Shell and Tube Design

The tube stack is packed with tubes and internal baffles to provide the largest and most effective surface area, enabling the unit to heat pools considerably faster than some competitors’ products.

Water Flow 

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.

Installation Diagram

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.
