About us

ISOIL with more than 60 years of experience in the industry is able to better meet the needs of all customers in the field of petroleum product measurement.


Our values

Values are what distinguishes Man in his actions in society and, for this reason, they belong to the sphere of ethics rather than that of technique.


How can we speak of values within a company that deals with manufacturing?

Because the company is made up of people who follow certain values also in their work and adhere to them in human relations. This is the spirit that our company has pursued since its origins: care for customers, partners and suppliers, respect for their work and a focus on solving problems, including technical ones, are the foundations of ISOIL’s activity.


Our experience

ISOIL was set up in 1958; for over 60 years it has been a landmark in the oil market with a calling for the energy sector. A focus on engineering, certified and tailor-made solutions and a worldwide sales network are the heart of our business: not just product quality but also an international support service based on trust and expertise.

All that has allowed us to be partners of many of the foremost oil companies in Italy as well as abroad.

ISOIL Impianti has always worked in the downstream sector but with an eye on the evolution of the market and of the world at large: biofuels and LNG are the starting point for growth aimed at respect for the environment.
