DENIS SERTAC

What DENIS SERTAC does

DENIS SERTAC is an industrial machinery manufacturing business unit of the French diversified group INDUSTRIES BY DENIS, headquartered in Le Chambon-Feugerolles, Loire. The company designs, fabricates, and commissions turnkey installations for handling powders and granules used in industrial manufacturing processes. Its product portfolio is organized into five integrated systems: storage (silos and hoppers in steel or stainless steel), dosing (automatic, modular, and gravimetric loss-in-weight stations), mixing (turnkey and mobile stations), pneumatic transport (dense, semi-dense, and dilute phase), and mechanical handling (Archimedean screws, bucket elevators, airslides, rotary and helmet valves, glove boxes). Technical differentiators include self-cleaning dosing screws with compressed-air injection, interchangeable mobile feeders allowing rapid formulation changes, and 50+ years of in-house rotary valve manufacturing for abrasive and high-temperature environments.

The business model is project-based, quote-driven B2B equipment sales with no public pricing. SERTAC operates an enterprise field-sales motion: industrial clients request quotes through a 'Obtenir un devis' contact channel, after which the company executes a full vertical chain — audit, design in its engineering bureau (bureau d'études), fabrication in workshops, on-site assembly, and commissioning by its own technician teams. A dedicated maintenance and technical assistance service supplements equipment sales. The company distinguishes itself through full in-house integration of engineering and production, eliminating reliance on third-party fabricators and intermediaries.

SERTAC serves enterprise customers across construction materials (VICAT, Lafarge, EQIOM, LHOIST, XELLA, WEBER SAINT GOBAIN, ISOVER SAINT GOBAIN, IMERYS, SIKA, JACOBI, ETEX, BONY), chemicals (KURARAY, ALTEO), environmental services (VEOLIA, SUEZ), building materials (BEISSIER, TOUPRET), industrial manufacturing (FRAMATOME), aluminum production (TRIMET), glass production (SAINT LOUIS), and food processing (BESSENAY). The company operates within a larger five-activity industrial group (DSO, SOMAIN, SERTAC, PROTECH, DSM) that shares a 12,600 m² covered production facility. Headcount is reported as 251–500 employees, and no revenue figures, funding events, or public listings are disclosed.

Broad incumbents

• Coperion GmbH (Hillenbrand): Global leader in compounding and extrusion, feeding, materials handling and bulk material handling systems, including rotary valves, pneumatic conveying and turnkey powder process installations. Much larger than SERTAC but competes directly for large industrial powder handling projects in cement, chemicals and minerals.
• Schenck Process Group: Large global industrial group offering conveying, weighing, dosing, screening and pneumatic transport systems for bulk solids. Competes with SERTAC in storage, dosing and pneumatic transport for cement, chemicals and minerals customers at the larger end of the market.
• Piab Group: Global supplier of vacuum conveying, gripping and material handling automation for powders and bulk solids. Adjacent to SERTAC's pneumatic transport offering and competes for powder transfer applications in chemicals, food and pharma.
