About Schmöle
Schmöle GmbH is a manufacturer of high-performance finned tubes, plain tubes, bent tube parts and heat exchangers with over 170 years of experience in tube bending. The company processes seamless and welded tubes with diameters of 6 to 30 mm made of copper, copper-nickel, brass, stainless steel, steel, aluminium, titanium and nickel-based alloys. Finning is performed using three processes: laser welding (Laserfin), rolling (Trufin) and brazing (Corrofin) on 16 finning machines; finned tubes can be produced up to 42 meters in one piece. In tube bending, U-tubes, meanders, hairpin bends and complex geometries are produced on CNC tube bending machines, complemented by sawing, deburring, tube end forming, brazing, welding, surface treatment and the manufacture of ready-to-install assemblies. The portfolio ranges from finned tube coils, coaxial and shell-and-tube heat exchangers to oil coolers (LOK) and tube bundles for large apparatus construction, as well as surface heat exchangers such as chilled ceilings, wall heating and ceiling radiant panels. Customer industries include plant and apparatus engineering, heating, refrigeration and air conditioning technology, mechanical engineering, automotive, nuclear power technology, machine tool and plastics machinery manufacturing.
