Ohmni is USI ITALIA's premium full-electric spray booth, where the air is no longer heated by fossil fuels, but by electric coil heaters (during the painting phase) and infrared emitters integrated in the panels inside the shell (during the drying phase).

A hybrid nature even in the name

The term ‘Ohmni’ merges ‘Ohm‘ – the unit of measurement of electrical resistance in the International System – with ‘omni‘, a derivation from the Latin adjective ‘omnis’, meaning ‘all’ or ‘of all kinds’. This choice is not accidental: Ohmni in fact represents extremely versatile technological ingenuity, where the electric heating unit is also a hybrid, in that it is designed to integrate and upgrade with different energy sources; available today. Or in the near future.

Ohmni: an innovative approach to traditional painting

Ohmni represents a radical innovation in the field of coating, embodying the vision of doing old things in a new way. In a world where carbon neutrality is an increasingly pressing international discussion topic, Ohmni offers a solution that reconciles tradition and technological innovation. Indeed, the goal of achieving carbon neutrality requires significant changes in energy production and consumption patterns.

During the painting phase, Ohmni uses traditional thermal convection to heat the air. However, it is during the drying phase that Ohmni stands out, utilising heat transfer by radiation. This advanced technology allows effective heating of the material regardless of the temperature of the surrounding air or other material media, thus offering a more efficient and less energy-intensive drying process.

With Ohmni, refinish industries can now aim for cleaner and more sustainable production, reducing their carbon footprint and meeting global sustainability goals.

SWIR Speed and MWIR Protection: a dynamic duo for infrared painting

Discover the Ohmni infrared spray booth, which combines the speed of the short wave SWIR with the safety of the medium wave MWIR for superior results. Thanks to SWIR emitters, the Ohmni booth ensures even and fast drying, penetrating deep into materials to dry even the most intricate interior parts without compromising quality.

Thick or complex structures are no longer a problem. Our advanced infrared drying technology ensures that every corner of the material is treated precisely, avoiding the risk of damage or uneven drying.

USI ITALIA engineers have perfected the SWIR/MWIR technology to suit a wide range of materials, developing ad hoc algorithms that optimise safety and performance. This focus on precision ensures not only energy efficiency but also strict compliance with safety regulations, making the Ohmni spray booth ideal for high-end industrial applications.
