Established in 1867, the company has been making electrostatic equipment since 1962 under the ELETTROSPRAY® trademark.
The first equipment has been entirely manufactured in Italy was the TURBODYN®. This was a manual electrostatic equipment with rotating bell.
The following developments have been the airspray unit PNEUMODYN®, the airless unit HYDRODYN® and the powder unit EPS®.
As long as a manual unit was developed its corresponding automatic unit has been designed to follow the industrial target toward fully automatic production processes.
From the beginning the ELETTROSPRAY® equipment range followed the sector evolution by using new technologies and expanding its production.
The applications of the electrostatic principle have been extended to field similar to industrial painting as the food industry and the steel mill.

During the years Ravarini Castoldi & C. deposited many patents of advanced devices, for the electrostatic application of many different products often tracing new ways as a result of a careful work in the research and development field.

In 1986 the company produced the first electrostatic oiler on demand of an Italian customer to be installed on one of its pickling lines.
Since the performance and easy maintenance of this first machine proved to be successful, other machines were supplied to the industry and the company was more and more involved in supplying the cold rolling mills and the aluminium industry with electrostatic oilers for the following types of lines:
- pickling lines
- cold milling lines
- slitting lines
- cut-to-length lines
- continuous annealing lines
- galvanizing lines
- inspection lines
- recoiling lines
- coating lines
- tin plate lines

Founded by Carlo Ravarini (1838-1912).
