Ammonia operator training in Minnesota was a great success to all. We are so grateful the partnership between CoolAir Mechanical and ARTS. We are expected to come to Minnesota several times a year with their support to teach various ammonia refrigeration classes. This class had participants from Minnesota, Michigan, Wisconsin, Iowa, and California! To get a quote for us to come onsite and provide a private training course see this link.
