  • Possibility of assistance
  • Subsidies available
  • Innovative solutions

To make this measure more effective and tailored to the specific context of your company, we recommend that you first perform an overall analysis of your energy situation.

Ultrasonic humidification in the proofing chamber

The project involves replacing hot steam generation with humidification based on ultrasonic low-temperature water mist.

Installing this technological innovation can allow the company to save up to 95% on electricity consumption during the humidification stage, as well as 5% during the cold generation stage. This measure is not easy to implement and would entail a medium-to-long term return on investment. The measure does not require a production shutdown while the technology is being installed.

Energy and environmental impact

Generating a water mist through a thermal process consumes 95% more energy than through a mechanical ultrasonic process. Further, proofing causes an exothermic reaction that requires cooling of the proofing chambers.

Ultrasonic humidification through adiabatic evaporation contributes to cooling, while the thermal process must be compensated by additional cooling.

Subsidy application

State subsidies

Please note: any application for government or non-government subsidies must comply with the “incentive effect”, subject to compliance with the subsidy conditions.
To ensure that the incentive effect of the aid is respected, no binding commitments may be made (acceptance of a quote; advance)

  • SME Packages – Sustainability
    • Flat-rate subsidy of €5.000 for small and medium-sized companies for projects to reduce their environmental impact, costing between €5.000 and €6.650 excluding VAT
    • For any questions:

N.B. While several state subsidies cannot be granted for the same project, they can be combined with assistance from energy suppliers.

Subsidies from electricity and natural gas suppliers

Since 2015, natural gas and electricity suppliers are required to make energy savings for consumers under the obligation scheme. Since then, energy suppliers have been offering support and advice, as well as subsidy programmes for consumers to implement energy efficiency measures. The amount of the premium is proportional to the annual energy saving (in MWh). The following suppliers offer this service for companies:

N.B.: Supplier subsidies can be combined with a state subsidy for the same project.
