What GYRO does

KREISEL Industries GmbH is a 113-year-old German specialist manufacturer of bulk material handling components, headquartered in Krauschwitz with additional operations in Thierhaupten and Blankenburg. Following self-administration proceedings initiated on 31 January 2025, the company completed restructuring on 1 May 2025 under a regional investor and rebranded from KREISEL GmbH & Co. KG to KREISEL Industries GmbH. The firm designs, engineers, and manufactures rotary valves (including standard, self-cleaning, and high-pressure/RotoFeed variants), slide gates, double flap gates, dome valves, two-way distributors, screw feeders, screw heat exchangers, dust collection systems (jet pulse filters, hot gas filters, cyclone filters, separators), silo equipment (air slides and dosing rollers), wear-resistant pipe bends, recuperators, and PressureFeed pressure vessel systems for pneumatic conveying.

The technology platform is anchored by proprietary wear-protection IP including UltraCarbide® armouring and ceramic lining at Mohs hardness 8.5–9.0, a described 'world-unique' self-cleaning rotary valve architecture using a second shaft with knife edges for forced emptying, and PressureFeed pressure vessels enabling long-distance conveying up to 6,000 m at pressure differentials up to 20 bar. The company holds ISO 9001:2015, ATEX 2014/34/EU, EN 1090-2 EXC 2, AD 2000-Merkblatt HP 0, and ISO 3834-2 certifications, operates 5,200 m² of production halls with 32-tonne lifting capacity, and runs a Technical Centre with bulk material analysis laboratory for customer testing and validation.

Revenue is generated through custom-engineered, project-based equipment sales delivered via direct enterprise sales (led by Head of Sales Components Carsten Mevius), supplemented by regional sales offices and independent commercial agents in Brazil, Portugal, France, and Poland. Primary verticals are cement and power generation, with mining/minerals and glass/ceramics as secondary segments. The company serves customers in over 100 countries, with named references including Zementwerk Karsdorf, Chelm Cement Works (Poland), and PPC Hercules (South Africa). Ancillary revenue streams include spare parts supply, installation and commissioning services, contract manufacturing (Lohnfertigung), and Technical Centre testing services.
