In 1968 Mr. Diana Sergio began to build the first silver recovery machines at industrial level.

After that, at the end of the Seventies, he created the Led Italia Company, in Pordenone.

During the time, the plants initially built were improved for making better the recovery of the silver contained in the fixer bath, bleach-fix, x-ray liquids, film liquids and graphic arts. In those years, were also planned the first equipment for recovering the silver contained in the x-ray film.

After the antipollution laws came into force, the plants for the treatment and the recycle of waste-waters were created, followed by the concentrators and vacuum evaporators.
The vacuum concentrators found application to different sectors, in particular to the galvanic, goldsmith and waste collecting companies.

In the cosmetic, chemical and pharmaceutical field these machines are used for purifing the processing and washing waters (for example waters used for washing emulsifiers and mixers), whereas in the herbal sector they are used for parting the extract from the solvent used for the extraction.

Just in this last sector, at the end of the Nineties, a new extraction’s system for the vegetable extracts production was planned and patented by using a new extraction technology (rapid solid-liquid extractors, Globus Extractors series, called Naviglio Estrattore).

These machines aroused a great success by many italian and foreign extraction’s and research companies.
At least, a series of plants was created to complete the range intended both to the medicinal herbs treatment and to the cosmetics production.
