Claro has an active digester mixer modernization & retrofit program that can update gas and other draft tube mixers within a very tight time frame & at a very competitive cost. These retrofit projects have primarily renewed smaller & major systems equipped with Cannon-type gas mixers. Our senior engineers are the inventors of the Cannon-type mixer. The Claro Big Bubble™ mixer is the next generation design of this mixing technology. A typical retrofit of Cannon-type mixers preserves the mixer draft tube & support structure. Modernized components include the AISI 316L patented bubble generator & inlet bell, AISI 316L flexibles & special-designed gas pipe guides.

Design features & advantages
  • A bubble generator designed to function in poorly screened digesters and provide full inspection and precautionary maintenance access to the mixer internals without tank drainage.
  • All stainless steel construction.
  • Highly cost-effective.
  • Quick turn-around – we can deliver upgrade components while the digester tank is undergoing maintenance. Installation time is minimal.
  • Complete design & installation support from the inventors of the piston-bubble gas mixer.
  • Maintain the performance and active volume for your digester and diminish the intervals between costly tank cleanings with a timely & cost-effective retrofit.
