Heat exchange coils - Import export

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.

The air handling unit (AHU) is a small piece of equipment for the simple treatment of air in small environments. It is usually composed of a single chilled water and hot water heat exchange coil, both for cooling and heating, or of a direct expansion coil in which the refrigerant gas circulates. Evaporation takes place in the coil itself within the rooms of use by an air filter and a low head suction/delivery fan. 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: Air exchange, Air purification, Humidity control

The PAD-V adiabatic system is the optimal solution for increasing the efficiency of air systems, with capacities from 75 to 1,100 kW. Dry operation during cold periods: ambient air is drawn in and conveyed to the heat exchange coils (where the fluid to be cooled passes through): no water in the circuit, as during standard dry cooler operations. Energy use is also optimized by electronically modulated fan speeds based on temperatures. Adiabatic operation during hotter periods: outside air passes through the humidifier pack to be pre-cooled, before being conveyed to the finned coils and performing its cooling function: efficiency is increased. This also makes it possible to work at lower ambient temperatures.
