Plant construction from a single source
KWS Strohmenger is an engineering and manufacturing company specializing in kiln and dryer construction, based in Neunkirchen am Brand in Bavaria. The company plans, designs and manufactures tunnel kilns (side-fired and top-fired), bogie hearth kilns, burner systems for natural gas, wood gas, heavy fuel oil and light fuel oil, circulation systems up to 850 °C, heat exchangers for heat recovery, dryer systems (chamber and tunnel dryers) as well as transport systems such as transfer cars and winch systems. The value chain covers everything from a single source, from design and manufacturing through software development, control cabinet construction (Simatic S7, WinCC) to plant optimization. Its main industries are the brick and ceramics industry; in addition, special dryers are built, for example for insulation foam panels. Since 1963, more than one hundred kiln and drying systems have been newly built worldwide, and countless existing systems have been converted and optimized. Materials include steel, stainless steel, ceramics, refractory and insulation materials.
