Digester produced biogas is 100% water saturated. The naturally cooling biogas, moving from the digester to the point of use will release large amounts of water into the gas pipework system. This has the potential to corrode pipework and damage mechanical plant.
To reheat biogas and reduce the relative humidity after natural or forced biogas cooling we provide a hot water / biogas tube shell heat exchanger, manufactured in 316 Stainless Steel. These biogas reheaters are designed to use available hot water on the site.
If hot water is not available then reheating using electric ATEX rated immersion heaters is another option to consider.
