Industrial Gas Burners Modulo+

In 2022, our Modulo+ burner range was extended with the introduction of four new models


  • Modulo + 2-ES (2.5 t/h boilers) NOx reduction
  • Modulo + 2-ET (3 t/h boilers)
  • Modulo + 2-FT (3.5 t/h boilers)
  • Modulo + 2-HT (4 t/h boilers)




These new models were born of the desire to bring the performance of Modulo + to smaller boilers:

flexible operation + lower NOx emissions + energy savings.

Today, the first commissionings and feedback have enabled us to assess the real, in situ performance of these new burners, and the results are more than convincing.

First of all, let’s remind ourselves of our performance commitments with regard to this equipment:

  • NOx < 80 mg/Nm³ @ 3% O2 sec
  • Modulation 1 to 12
  • Optimum excess air throughout its operating range

To meet the needs of a distillery in Le Havre (76), two Modulo+ 2-ET burners were installed in July 2023 on BWD 30A boilers. The result? NOx emissions of less than 65 mg/Nm³ and operating savings of +0.6%.

In November 2023, at Compiègne (60), a Modulo+ 2-HT burner was fitted to a SteamPack 4.0 boiler used by a cosmetics manufacturer. Here again, the results are more than convincing, with NOx emissions of less than 70 mg/Nm³ and operating savings of +1.1%*.

Most recently, in December 2023, 3 Modulo+ 2-HT burners were delivered to equip SteamPack 4.0 boilers for a pharmaceutical industry customer in Toulouse (31). Initial feedback after commissioning shows NOx emissions of less than 70 mg/Nm³ and an operating gain of 0.75%.

In conclusion, the expansion of the Modulo+ range is a real asset in offering our customers high-performance burners that deliver substantial energy savings and a significant reduction in NOx emissions.

*: The operating gain is calculated on the basis of an estimated average load for each boiler compared with a standard OPTIMO burner.



If we consider that one tree stores around 167 kg of CO2 per year, or 1 tonne of CO2 per year for 6 trees, we can estimate that for these three customers, the equivalent of 490 trees, or more than 80 tonnes of CO2, have been avoided.
