Established in Milan since 1867 our company has been making electrostatic equipment since 1962 under the ELETTROSPRAY^® trademark.
The first equipment has been entirely manufactured in Italy 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 her 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 very successful other machines were supplied to the industry and our 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

We can no longer ignore the fact that ELETTROSPRAY^® Electrostatic Oiling machines and engineering quality are increasingly in demand, as recent successes the world over have demonstrated.

Now Ravarini Castoldi & C. is proud to be offering one of the widest range of electrostatic equipment in the world.
