About SINGLE
SINGLE Group GmbH, headquartered in Hochdorf (Baden-Württemberg), has been developing and manufacturing industrial temperature control and cooling systems since 1968, covering water and oil temperature control, liquid cooling, variothermal temperature cycling systems (ATT), SFC water distributors as well as cooling and heating systems for test benches. The portfolio ranges from series water temperature control units (90 to 225 °C) and high-temperature oil temperature control systems up to 350 °C, to cooling systems with cooling capacities up to 40 kW, and on to individually engineered special systems and system solutions, including design, manufacturing, final assembly and commissioning. The systems control temperatures with a resolution of up to ±0.1 °C and, depending on the application, can reduce process energy consumption by up to 70%. Typical construction materials are stainless steel (optionally an all-stainless-steel version for cleanrooms), stainless steel 1.4408 for dirt traps and Incoloy for heating elements. Industries served include semiconductor technology, battery technology, plastics and elastomer processing, aerospace, automotive/e-mobility, medical technology, chemicals/pharmaceuticals, packaging, food, as well as mechanical and plant engineering. With its own subsidiaries in Germany, Poland, the USA and China and more than 200 employees, SINGLE supplies customers in over 30 countries.
