Every two years the “Tankstelle & Mittelstand” trade fair is held in Münster, Germany. The fair covers a complete range of equipment and services for filling stations, including convenience store sales. Visitors to this year’s fair had the opportunity to see a Mistral CCU refrigeration unit from Green & Cool in operation. CCU is the model designation of one of several compact units equipped with an integrated gas cooler that Green & Cool has developed especially for smaller retail outlets. Visitors were impressed by the small size and quiet operation of the unit, as well as its environmental and economic performance.
