Process Technology for Environment & Industry
Prantner GmbH Verfahrenstechnik, based in Reutlingen, develops and builds systems for exhaust air purification, water purification and soil remediation. The company was founded in 1970 as an engineering office and converted into a GmbH in 1985; for over 40 years it has supplied industrial companies worldwide – with more than 7,000 systems delivered in over 33 countries. The portfolio includes thermal, catalytic and regenerative post-combustion systems, concentration systems with adsorption rotor, activated carbon filters, catalytic ammonia oxidation, gas scrubbers and stripping systems for groundwater purification. The systems are predominantly made of steel and stainless steel, partly of plastic or electrically conductive PE, often in container or modular design. Customers come from the chemical, pharmaceutical, semiconductor, automotive, printing, painting, plastics and food industries as well as the municipal sector. In addition to process development, engineering and project execution, Prantner offers measurements, activated carbon service, maintenance and commissioning.
