Key fact Recovered heat + cleaner gases
01 — Understand
Terrao technology, in three points
TERRAO directly mixes air or flue gas with water to achieve near-complete heat and mass transfer between the two fluids. This process washes the air or flue gas and recovers both latent and sensible heat; regenerating the water then removes the captured pollutants.
01 The solution
Heat recovery and pollution removal from air or flue gases.
02 Technology principle
Direct contact between gas and water transfers heat and matter, washes the gas stream and then removes pollutants as the water is regenerated.
03 Applications
- Flue-gas treatment
- Air purification
- Heat recycling
Terrao develops an innovative technology to reduce air pollution from industrial and human activity. Its combined heat-and-mass exchanger directly mixes air or flue gas with water, providing near-complete transfer of heat and substances between the two fluids. The process cleans the gas while recovering its latent and sensible heat.
Protected by several patents, TERRAO® provides a family of solutions for air quality and the energy transition. Its three principal applications are heat recycling, flue-gas treatment and air purification.
After the direct exchange removes pollutants from air or flue gas, regenerating the water extracts the captured contamination. Each configuration is adapted to a specific need and contributes to an integrated approach to pollution control.
Three complementary solutions
- TerraoTherm focuses on heat recycling.
- TerraoSave treats flue gases from industrial processes.
- TerraoPure purifies air.
Together these systems address gas and flue treatment, heat recovery and recycling, and air disinfection. Terrao combines pollution control with practical industrial energy-transition measures.
