About Apparatebau Allenspach AG
Apparatebau Allenspach AG, headquartered in Hermetschwil-Staffeln (AG), is a full-service provider of process engineering industrial plants. The company plans, designs, manufactures and installs systems for the thermal and catalytic post-combustion of gaseous pollutants (TNV/TO, RNV/RTO, KNV/CTO), high-temperature heat exchangers, systems for industrial process heat generation, and web drying ovens for paper, film, aluminium and steel as roller-suspension and flotation ovens. In addition, Allenspach supplies concentrators and molecular sieves as upstream stages, ventilation components, as well as complete exhaust air, steam, thermo-oil and hot water networks including installation, inspection and maintenance. RTO systems with a 3-chamber system and ceramic heat storage media treat exhaust air volume flows of up to 120,000 Nm³/h; oxidation takes place, depending on the application, at 820–950 °C. The company has been active for more than 40 years and operates worldwide, including projects in Switzerland and the USA (Columbus, Mississippi). Customers include Hans Kaspar AG, Lobra AG and EnVPro.
