Air conditioner - Import export

Air conditioning is the operation by which the parameters of relative humidity, temperature and air speed are modified. For this sector, our company deals with the production and sale of copper and iron pipes which can be semi-finished or assembled suitable for different purposes, including: Improve people's well-being. Maintain suitable environmental conditions for the correct conservation of everything that is subject to temperature variations and requires a constant temperature. Allow the correct operation of equipment, removing the heat generated by use and maintaining the temperature constant for correct operation.

Our company has been manufacturing finned coil heat exchangers for over 40 years. The design of each finned pack can be totally developed inhouse by Stefani or taken from a drawing supplied by our customer. This is possible thanks to a strategic coengineering service, which is necessary especially when developing specific designs. In the design and manufacture of our finned coil heat exchangers we put all the flexibility and competence that have always been the hallmark of our work. We make customised finned packs for production in batches, dedicated to the machines of our OEM customers and, in general, to data centres, air treatment units for industrial refrigeration, industrial and commercial air conditions and condensing units for refrigeration.
