Read the Report

Our analyzer cabinets are custom made to meet the exacting specifications of many different petrochemical, natural gas and chemical customers. We integrate a variety of analytical instruments and electrical equipment into a man-sized cabinet up to 140 cubic feet (4 cubic meters) in size. We typically recommend Friedrich Hazardgard room AC units because they can handle up to 130°F ambient temperatures in a hazardous environment where constant runtime is required.
