What Körting Hannover does

Körting Hannover GmbH is a privately held German industrial engineering company founded in 1871 and headquartered in Hannover, Germany. It designs and manufactures custom-engineered vacuum engineering and environmental technology equipment — including steam jet ejectors, jet compressors, multi-stage steam jet vacuum systems, condensers, mechanical vacuum pumps, gas scrubbers, swirl droplet separators, caustic recovery plants, and process engineering systems — for industrial customers in the chemical, petroleum refining, textile finishing, steel degassing, power generation, shipbuilding, pulp and paper, water treatment, edible oil, polyester, hydrogen, and refrigeration sectors. All engineering, production, testing, and commissioning capabilities are integrated under one roof at the Hannover facility.

The company goes to market through a combination of direct enterprise field sales, five wholly-owned regional subsidiaries (China, India, Malaysia, the United States, and Brazil), and a network of regional distributors covering an additional 13 countries across Europe, Africa, South America, and Asia. Pricing is project-based and not publicly disclosed, with customers submitting technical inquiries for tailored proposals; lead generation is supplemented by participation in major industrial exhibitions such as SMM, IFAT India, ITMA, and ACHEMA. Recent product activity includes the 2025 launches of a controllable steam jet compressor (delivering approximately 30% energy savings at up to DN 2400 in Chinese district heating) and a hot gas quench / hot gas scrubber system (rated to 1,200°C), plus a 2024 caustic recovery plant delivery to Kaltex generating over USD 4 million in annual customer savings.

Körting's competitive position rests on 150+ years of accumulated engineering heritage, proprietary design know-how in steam-jet and gas-handling equipment, and an extensive pressure-equipment certification portfolio (ISO 9001, ISO 45001, PED 2014/68/EU, AD 2000 HP0, ISO 3834-2, ASME U stamp with National Board registration, China SELO licence, and EAEU TP TC 010/2011 and TR TS 032/2013 declarations). The company is managed by a two-person Board of Management — Dr.-Ing. York Fusch (Chairman) and Dipl.-Kfm. Martin Fusch — and operates as a privately held GmbH with no disclosed parent company or external investors.

Functional benefit

Products and services

• Steam Jet Ejectors Multi-stage steam jet ejectors and vacuum pumps that use steam as motive fluid to generate vacuum levels for industrial processes. Used by chemical, petrochemical, pharmaceutical, and other process industry plants that require robust, simple vacuum generation without moving parts.
• Controllable Steam Jet Ejectors Steam jet ejectors with integrated rotary slide control for modulating vacuum/pressure and reducing steam consumption compared with fixed-ejector designs. Targeted at process plants seeking energy-efficient vacuum control.
• Liquid Ring Vacuum Pumps Liquid ring vacuum pumps designed for industrial process vacuum, including handling of wet, corrosive, or particle-laden gases. Used across chemical, plastics, textile, food, and power generation applications.
• Rotary Piston Blowers Positive-displacement rotary piston blowers for delivering oil-free, pulsed air or process gas at moderate pressures. Used in industrial processes such as pneumatic conveying, wastewater treatment, and process gas handling.
• Jet Scrubbers Jet scrubbers that use motive fluid to entrain and clean contaminated gas streams for exhaust air and process gas cleaning. Used for emission control and gas treatment in chemical, pharmaceutical, and industrial manufacturing.
• Plate Scrubbers Plate scrubbers for wet scrubbing of exhaust air and process gases, designed for targeted removal of pollutants. Used by industrial operators that must meet emissions and clean-gas requirements.
• Exhaust Air Scrubbers Engineered exhaust air cleaning systems that combine jet and plate scrubber technologies for industrial emission control. Targeted at customers needing compliance with workplace and environmental air quality standards.
