Why VAREGAENVICOM® Burner?

Thanks to its regenerative heat recovery system, the VAREGAENVICOM® bruner offers outstanding energy efficiency—reducing operating costs while protecting the environment.

Its well-engineered design ensures low maintenance requirements and an extended service life, making it a long-term investment for melting furnace operations.

While versatile enough for various furnace types, the burner has been specially optimized for melting applications, with a strong focus on minimizing emission—particularly nitrogen oxides (NOx) and carbon monoxide (CO)—actively contributing to cleaner air and a more sustainable production environment.
