The sludge heat exchanger, or Komax Klean-Wall® Heat Exchanger, is mainly utilized for heating municipal sludge, FOG (Fats/Oils/Grease), or manure for aerobic/anaerobic digestion purposes. It is typically installed in a recirculation loop with a digester. Our custom sludge heat exchanger can specifically be used to heat sludge using hot water OR to reclaim heat from hot outgoing digested sludge to heat the cold incoming sludge, enhancing biogas production and assisting in producing Class A biosolids. Heating sludge to harness energy by capturing the biogas is a green practice utilized around the world in sustainable farming to capture methane gases. The biogas can be used to recover energy and generate power using a generator, and this energy can be used to power the other plant operations.

Xchanger is a leading manufacturer of custom heat exchangers and blower aftercoolers, with over 25,000 units installed worldwide. We can optimize any of our 10 standard product models to control temperature and humidity in almost any application. By making simple changes to our standard models, our Mechanical Engineers are able to provide custom designs at a fraction of the cost. We offer fin-tube and plate-fin heat exchanger surfaces, many construction materials to choose from, air-cooled and liquid-cooled designs, and explosion proof, severe duty, and inverter-duty motors. Our BG Series heat exchangers are especially relevant to the industry, as they cool and dehumidify Bio Gas streams, commonly found in landfills and digesters.
