Claro designs & manufactures three proprietary types of heat exchangers that heat, cool, & recover thermal energy by means of water-to-sludge energy transfer. Claro modular tube-in-shell heat exchangers, large gap heat exchangers, & Big Bubble™ mixers with heating jackets can suit a wide variety of applications & footprints. Claro heat exchangers are designed for:

  • Optimal heat transfer efficiencies.
  • Small, flexible, or even near-zero footprint arrangements.
  • Poorly screened process liquids without plugging.
  • Quick & direct access to heat exchanger internals.

Let us suggest which technology best meets your application requirements.

ModuTube™ Sludge Heat Exchangers – Wastewater Treatment Process
Claro Modular Tube-in-Shell Heat Exchangers
  • Selected features: modular construction; easy to install—even in difficult-to-access areas (ideal for retrofit applications); small & flexible footprints (ideal for reducing new facility infrastructure costs); simple capacity expansion, non-clog design, fully-accessible internals, & more.

For more information please see Claro ModuTube™ Tube-in-Shell Heat Exchangers.

Claro Large Gap Heat Exchangers
  • Selected features: easy to install; very compact & flexible footprints; non-clog design, fully-accessible internals, & more.

For more information please see Claro Large Gap Heat Exchangers.

Claro Big Bubble™ mixer with Heating Jackets
  • Selected features: Equipped with heat exchanger jackets, Claro Big Bubble™ Mixers integrate heating into the process tank enabling the elimination of external heat exchangers, associated sludge pumps, & piping. Mixing & heating integrated into a single, high-efficiency system.
