SPX Corp. controls the ebb and flow of multiple industries. The company operates in a couple of areas: thermal equipment and services (cooling, heating, ventilation) and industrial products and services (compactors, power systems, broadcast antenna systems, aerospace components). SPX serves core markets which include infrastructure, processing equipment, and diagnostic tools. In turn, these markets support electricity, processed foods and beverages, and vehicle services. It operates in 20-plus countries with a sales presence in 100 countries. In mid-2015, SPX spun off its flow technology operations (pumps, valves, other fluid handling devices).
