Leverage the Power of Heat with the Komax Klean-Wall™ Heat Exchanger

Across industry lines, saving energy is a huge problem for many organizations, and heat exchangers were designed to utilize as much of that energy as possible, but they’re not always quite as efficient as they could be. Komax Systems, though, has implemented state of the art technology to the world of heat exchangers, providing you with the best possible system in the industry.

Efficiency – Redefined


Looking for higher efficiency ratings? You’re not alone. The Klean-Wall Heat Exchanger Technology means a 300% increase over the standard slurry heaters, tube and shell exchangers. It is typically installed in a circulation loop for large digester heaters, reducing retention time by up to 50%. Take a look at a few of the other advantages of this sludge heater technology:

  • It Won’t Clog! Our Klean-Wall System can pass debris up to 50% of the diameter of the pipe, even stringy rope-like debris without plugging.
  • Eliminate Wall Buildup! Municipal sludge and other materials can pack those walls thick, but our efficiency doesn’t degrade over time, and the high level of turbulence at the boundary walls helps eliminate that constant build-up. The turbulent sludge is constantly scavenging the wall surface to help eliminate fouling.
  • Increased Bacteriological Activity! You’re going to see a real increase in bacteriological activity and improved digesting thanks to the shearing and sludge mixing.
  • No Cleaning Required! This heat exchanger should never require cleaning, but if you want to do a bit of preventative cleaning to set your mind at ease, our unique Hi-Pass design means a clear pathway down the center-line for your hydro-rod.
