Bitzer celebrated its newest Oakwood facility on Tuesday, with company leaders guiding tours through a warehouse where compressors for refrigeration and air conditioning are manufactured and holding a ceremony with leaders from the German company and the Hall County community. The 95,000-square-foot expansion represents an additional 50 jobs and a $10 million investment, leaders said at the ceremony outside the building on Enterprise Way off Thurmon Tanner Parkway. Hall County Board of Commissioners Dick Mecum said the 50 employees are salaries paid into the community and "when you spend money locally, it rolls over."
