Born from a strong idea, to make history.

Turning talent and passion into useful objects for people and their communities.


The company "D. Guerra" was founded in 1956 by Benito Guerra with a pioneering spirit: creativity, research, development and production of new solutions and a commitment to continuous improvement.

An idea that contained entirely in the strength of one word: Robur. And a winning idea: the production of gas nozzles for water heaters and boilers, within the context of increased use of natural gas in Northern Italy, which quickly transformed the company into a market leader.

In 1967 the Robur laboratory was founded, with the task of guaranteeing product development and anticipating the market. An enlightened choice that produced the multigas atmospheric burner in 1969 and the patent for a high-efficiency, low-emission burner in 1973.

In 1976 the search for efficiency and simplicity, and the desire to have a product all of its own, led to the idea of "heating that can be turned on and off like light", with Robur gas unit heaters. A product that immediately demonstrated its success. In 1982, production was expanded with individual gas-fired convectors to integrate the heating of civil and commercial environments. These were the years in which innovation revolutionized the international market.


GAHP, absorption heat pumps using natural gas and renewable energy, were created based on the studies of one of the brightest minds of the last century: Albert Einstein, and were realized and developed in the United States, in Evansville, Indiana.

Robur acquired absorption technology from Dometic, an Electrolux Group company, in 1991.

GAHP heat pumps introduce a new concept to the market: the highest thermal efficiency through a single natural gas unit for heating and air conditioning, capable of using more than 50% renewable energy. An epoch-defining achievement, to which is added the natural gas and renewable energy absorption heat pump for the residential sector: K18.

In 2019 Robur is undergoing a renewal, with a new Board of Directors and a new president, and in 2021 it will celebrate its 65th anniversary, with important news on the horizon.

Ready to meet the new challenges of the future.
