In certain HVAC applications, corrosion does not begin on the visible surface… but rather on cut edges, joints and exposed areas.
For this reason, Casals incorporates the Magnelis® coating into a selection of fans and ventilation boxes designed to operate in particularly demanding environments.
Thanks to its zinc, aluminium and magnesium composition, Magnelis® provides superior corrosion protection compared to traditional galvanised steel, especially in humid, industrial or saline environments.
But…
does every installation really require Magnelis®?
Although Magnelis® offers significant advantages in aggressive environments, not every HVAC installation requires this level of protection.
In dry indoor applications or controlled environments, standard galvanised steel may be a perfectly suitable and cost-effective solution.
That is why we have developed a guidance tool to help you select the most appropriate coating according to:
The tool allows you to quickly, for guidance purposes, assess whether the application requires:
