Fluid enters the outer ‘shell’ of the unit and travels over a series of specially designed baffles, transferring energy from the exhaust gases which travel through the tubes of the heat exchanger.
Fully welded construction using 316 stainless steel ensures maximum reliability and durability of the unit, when handling extreme exhaust gas temperatures.
The automated tube end welding process of the tube core ensures ultra-high quality, whilst every unit is 100% inspected for structural integrity.
Bowman exhaust gas heat exchangers are renowned for their high quality, which translates into long-life durability, even where more aggressive fuels, such as biogas, are used.
In addition to offering a more compact packaging solution, right angle end covers often reduce system pipework requirements and enable the tubes to be cleaned, without disturbing the pipework.
Bowman exhaust gas heat exchangers are fitted with a pressure relief valve which automatically activates, should the pressure exceed 4 bar, to prevent excess pressure build up.
The following information offers a general guide to the performance and dimensions of our standard range of exhaust gas heat exchangers.

A heat exchanger is a device for transferring heat energy from a liquid or gas, to another liquid or gas without the two ever coming into contact with each other. A typical shell and tube heat exchanger will contain a tube bundle inside an outer shell, or body. Cold water flows through these tubes, whilst hot water, or gas flows around the outside of the tubes, enabling the heat from the hot water or gas to be transferred to the colder water inside the tubes.
A good example of how the process works are swimming pools, where most are heated via a boiler, using Gas, LPG or Biomass as the energy source. In theory, the most efficient way to heat the pool would be to circulate the pool water directly through the boiler. But were this to happen, the chemicals used in the pool water to keep it safe for use, would quickly corrode and damage vital parts inside the boiler, leading to premature failure and a costly replacement.
However, by using a heat exchanger to act as an ‘interface’ between the boiler water circuit and the pool water circuit, the boiler is protected from damage and the pool water is quickly heated up to the required temperature; the pool water passing through the central ‘tube core’, whilst the hot boiler water circulates around the outside of the tubes, transferring heat energy to the pool water.

Selecting the correct heat exchanger is very important to ensure the pool heats up quickly to desired temperature. The main issues to consider when sizing a swimming pool heat exchanger are;
