Born in the US from a big idea – to make history.
Welcome to Robur Corporation.

Turning talent and passion into useful objects for people and their communities since 1956.

ROBUR Corporation was founded in 1991 and was the brainchild of our founder Benito Guerra, an Italian entrepreneur and owner of the sister company Robur, a leading manufacturer of Advanced Heating and Cooling Technologies sold throughout Italy and Europe since 1956, whose main aim is to turn talent and passion into useful objects for people and their communities, focusing on the environment in which they live.

This led ROBUR to create GAHPs (Gas Absorption Heat Pumps) using natural gas and renewable energy, based on the studies of one of the brightest minds of the last century: Albert Einstein. They were made and developed in the United States, in Evansville, Indiana.

This bold step insured future growth opportunities for ROBUR, along with a distribution channel for its European products throughout the North American market with the development of 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.

At our facility in Evansville, ROBUR Corporation manufactures and distributes natural gas operated heating, air conditioning and refrigeration systems that are highly energy efficient and have a low environmental impact.

In addition to being the North American Service Center for all ROBUR products, the Evansville location also provides spare parts for Servel and Arkla chillers.

In 2021 we celebrated our 30th year of business, and we're ready to meet the new challenges of the future for the next 30 years.
