Solution 1 — Waste heat recovery

Recover the heat you reject. Put it to use.

Your kilns and equipment constantly reject untapped heat. We design and install systems that recover this waste heat and reinject it where your process needs it — as hot air, hot water, or steam.

Turnkey, with or without investment
Stable heat costs, measurable decarbonization

The problem

Furnaces and industrial processes lose heat. We recover it.

Tunnel kilns, batch kilns, dryers, spray dryers, ovens, boilers, compressors...: your equipment constantly rejects heat. This energy can be captured, stored and released to feed other equipment, preheat your raw materials, maintain process temperatures or be resold.Tunnel kilns, batch kilns, dryers, spray dryers, ovens, boilers, compressors...: your equipment constantly rejects heat. This energy can be captured, stored and released to feed other equipment, preheat your raw materials, maintain process temperatures or be resold.

Thanks to the Eco-Stock®, our high-temperature thermal storage system, recovered heat is not delivered immediately — it is stored in ceramic blocks and released on demand, at the right time, at the right temperature. Your processes gain flexibility and stability, regardless of production variations.

Industrial furnace — waste heat recovery

What you gain

What you concretely get.

Savings on your gas bill

Direct reduction of your natural gas consumption and transportation costs.

Heat delivered on demand

Thanks to thermal storage, recovered heat can be stored and delivered when your process needs it.

No impact on production

Our installations are designed to integrate into operating sites. Critical interventions are scheduled during your planned shutdowns.

CO₂ emissions reduction

Waste heat recovery and reduced consumption lead to a reduction in your carbon emissions. Direct impact on your decarbonization policy.

Am I eligible?

Use cases.

We work with sites that have an exploitable waste heat source, that have committed to a decarbonization policy aimed at reducing fuel consumption, or that wish to achieve savings on their energy bills.
