The verticalisation and internalisation of processes are hinge points in the production strategy of Stefani S.p.A.
In fact, the company makes nearly all the components of ventilated units on its own premises: heat exchange batteries, manifolds, metal structures.
The advantages of this method lie in the full control of quality, in flexibility of production and in the guarantee of short and sure delivery times in any period of the year.
Stefani also has the competence and the experience necessary to make designer products, with the possibility of using various materials (copper, brass, aluminium, stainless steel, etc.), to carry out protection treatments for use in aggressive environments, and to use construction forms different from the market standard (round or folded batteries, etc.).
