FLU-ACE® Heat Recovery  


Reduce your fuel bills by 10% to 20% with Thermal Energy International’s FLU-ACE® heat recovery technology. 

For every $1,000 in fuel purchases for your boilers, $200 or more is wasted up your exhaust stacks. FLU-ACE® can typically recover up to $180 (or 90%) of that wasted energy and recycle it back into your processes and / or heating systems.

The FLU-ACE®​ can also be used to save even more money recovering heat from power generation systems, evaporator exhausts, dryer exhausts, and other industrial heat sources.

FLU-ACE®​ is a direct contact condensing heat recovery system that recycles the heat normally lost through the boiler flue gas exhaust.

The key benefits are:
  • Reduce energy consumption on boilers by 10% to 20%;
  • Enjoy full payback in two to four years… with continued savings throughout the unit’s 20 year + operational life;

  • Reduce greenhouse gases and other emissions commensurate to fossil fuel reductions;
  • Achieve typical water temperatures of up to 63°C/145°F (up to 82°C/ 180°F with alternate design);
  • Recover 200% to 300% more heat than conventional recuperator and economizer systems … heat readily usable for process water and air heating; and
  • Recover and condense between 70% and 90% of the water vapor normally vented in the exhaust gas… providing water for recycling to process.

FLU-ACE®​ is a well-documented and proven technology that has been helping our customers save energy and reduce carbon dioxide emissions for over 20 years.
