Take off towards a greener future with IESI by Comex Group! Our innovative flue gas-to-water heat recovery system transforms a byproduct of the aluminum foundry, such as exhaust fumes, into a valuable resource: hot water to power vacuum evaporator-concentrators. An intervention that combines environmental sustainability and economic efficiency.

In a recent project at an aluminum foundry, Comex Group successfully implemented the IESI system for heat recovery from melting furnace flue gases. The goal? To transform the wasted heat into useful hot water for powering a vacuum evaporator-concentrator, a key component of the process cycle.
Advantages of Flue Gas Heat Recovery with IESI
Choosing IESI technology for flue gas heat recovery offers concrete and measurable advantages for aluminum foundries:
- Sustainable Hot Water Production: Reduce dependence on traditional energy sources by producing hot water efficiently and environmentally friendly.
- Significant Fuel Savings: Our intervention resulted in fuel savings of a remarkable 166,500 m³/year of natural gas, leading to lower operating costs.
- Reduction of CO2 Emissions: Actively contribute to environmental protection with a reduction of 318 tons of CO2 per year, a significant step towards cleaner production.
- Rapid Return on Investment (Payback): The effectiveness of the IESI system translates into a payback of just 26 months, demonstrating how sustainability can also be economically advantageous.
IESI for Vacuum Evaporator-Concentrators
The application of flue gas heat recovery to power vacuum evaporator-concentrators represents a smart solution for optimizing energy consumption within the production cycle of aluminum foundries. IESI integrates perfectly into this process, maximizing efficiency and reducing environmental impact.
