Design is fundamental in the construction of a product such as a Coltri compressor, but there is no concept that can work without using best materials. Our drive for constant innovation has therefore led us to adopt Nikasil for our aluminium cylinders.
What is Nikasil? Nikasil is a nickel and silicon alloy which our cylinders are coated with to obtain less friction during the movement of components, greater resistance to abrasion and higher speeds for top performance.
This precision treatment must be obviously performed by high level professionals, that's why Coltri relies on a company that is a leader in this kind of processes. We choose the experience of Gilardoni.
Gilardoni has always been a point of reference for everything related to cylinders. The company produces and works a wide range of products for different uses, with an eye to the most professional needs such as aeronautical and competitive applications. Gilardoni has conceived a new way for the application of Nikasil, the GILNISIL®. The GILNISIL® coating is represented by a nickel base with very fine solid particles of silicon carbide distributed in variable percentages according to the treatments.
Joining another company that represents the best of Made in Italy allows us to create more and more performing and resistant components according to a tailor-made process based on our needs, changing the application methods and formulations for each type of machine we produce.
