What Renk Zanini S A Equipamentos Industriais does
Renk Zanini S A Equipamentos Industriais is a Brazilian industrial equipment manufacturer founded in March 1976 as a joint venture between Zanini (Sertãozinho, São Paulo) and Renk AG (Augsburg, Germany). The company designs, manufactures, and services special speed reducers and multipliers (turborredutores, planetary gearboxes, bevel gear pairs, and couplings) for critical-duty applications across sugar and ethanol, mining, cement, steel, oil and gas, naval, metro-railway, rubber, power generation, hydrogeneration, and wind sectors. The technology base is anchored by a continuous technology transfer agreement with Renk AG signed in 1983, which replicates German engineering standards (DIN/AGMA, cemented and ground gearing in EN 18CrNiMo7-6 steel) at a 174,000m² campus in Cravinhos, São Paulo, with 16,000m² of built area and Brazil's largest gas cementation furnaces.
The product portfolio includes proprietary brand lines such as TorqMax (sugar mill drive systems with 400+ units operating for nearly 30 years), Revolution Planetário, Duomax, FlexiMax, PentaMax, Combidrive, Vertidrive, Turbomax, and the CheckMax online monitoring system. The company holds API 613 and API 677 certifications, Petrobras CRCC qualification, ISO 9001 (first in Latin America), ISO 14001, and is the only Brazilian manufacturer qualified by the Brazilian Navy for large naval gearboxes. Quantified market positions include an 80% share of Brazilian cogeneration projects, presence in 90% of Brazilian tire factories, and more than 1,100 turborredutores commercialized globally.
The business model is project-based, B2B direct sales with custom-engineered quotations, executed through 8 regional Brazil key account managers, 2 export key account managers covering Latin America, and a representative network across Argentina, Chile, Colombia, and Venezuela. Revenue is generated from one-time equipment sales, 24/7 field service and maintenance contracts, reverse engineering and repotenciamento (upgrade) work, and machining/heavy boiler fabrication through the Zanini Serviços subsidiary. The company earns incremental recurring revenue from parts, couplings, and internal heat treatment services for gears and components.
