About AEROTECNICA COLTRI S.p.A.
Carlo and Giuseppe Coltri started manufacturing compressors in the late 1960s. Today, Aerotecnica Coltri Spa is one of the most important companies worldwide in the design and construction of high-pressure compressors for pure breathing air and technical gases.
We started with high-pressure compressors to refill diving cylinders, as used in recreational and military applications. Eventually, we added fire-fighting compressors for ground use, along with industrial gas compressors for nitrogen, argon, helium and Nitrox mixtures for diving equipment, with a maximum oxygen content of 40%.
Recently, with the increased proliferation of natural-gas vehicles, we have begun to manufacture compressors to refill the CNG cylinders used in such vehicles.
Aerotecnica Coltri Spa has an in-house workshop that processes and obtains nearly all the components from die casting or bars or drawn bars using state-of-the-art CNC tool machines and horizontal machining centers. We guarantee a high-quality product, using methods that ensure maximum precision and very tight tolerance against high pressures. That way, we prevent the leakage of lubrication oil, which is filtered and separated to ensure its absence from the contents.
The production cycle starts in a nearby foundry, which provides cast iron and aluminum for cylinders and casings. Our palletized horizontal machining center allows us to obtain a high-quality product. The templates and clamping systems of the single blocks and other components remain fixed. Thus we prevent any variation in calibration or measurement. Highly qualified personnel not only run these machines but also oversee the robotic cells.
Our company consists of four interconnected facilities. However, the pumping units of the major machine line are assembled in a separate facility. The overall covered area is approximately 8,000 square meters, and we have a staff of nearly 50 people.
Currently, we're developing a project involving our patented nickel and silicon galvanic coating cylinders.
