What CIDEX Composite does

CIDEX Composite SAS is a French manufacturer of custom composite tanks and silos in polyester resin (fiberglass-reinforced polyester / PRV), operating from a single ultra-modern factory in Treffendel, Brittany, established in 2012 as a subsidiary of the family-owned industrial group Christien Défi (whose origins date to 1954). The company produces storage and process vessels in capacities from 4 m³ to 100 m³ across five distinct manufacturing processes — RTM injection, filament winding, vacuum infusion, simultaneous projection, and contact molding — with a stated unique-in-France capability in large-part RTM that yields bacteria-free dual-smooth surfaces. An internal CAD/CAE design bureau with three stations handles bespoke engineering, structural calculations, and validation; metal accessories are produced by sister company Cidex Chaudronnerie.

The company operates a fully integrated A-to-Z project model: in-house design, fabrication, transport (two tractor/semi-trailer/auxiliary crane convoys), on-site installation by in-house driver-installer teams, and after-sales service. There are no distribution intermediaries and no public price list; pricing is quote-based, tied to capacity, fittings, and installation scope. The five primary customer verticals are livestock farming (silos for animal feed, powders, minerals), agri-food (food-grade silos for flour, sugar, oils), water treatment (cylindrical tanks, clarifiers, separators for water and effluents), industrial (ATEX-certified silos for salt, plastic granules, minerals), and a smaller subcontracting / custom composite parts service.

CIDEX Composite sells primarily into the French domestic market, with the broader Christien Défi group coordinating export activity across Europe (Spain, Poland, Belgium), the Middle East, Africa, South America, and Asia. Certifications include GDPR/RGPD compliance, ATEX for explosive atmospheres, EN 13121-3 mechanical design, and food-grade resin compliance with NF 85010 safety ladder standard. Digital presence includes a website, LinkedIn corporate page, YouTube channel, and paid campaigns on Google, Bing, LinkedIn, Facebook, and Twitter. Cumulative installed base exceeds 20,000 silos and tanks in France, with documented product lifespan of 30+ years.

Products and services

• Silos for Breeding (Élevages) Polyester fiberglass silos for storing animal feed (powders, minerals, liquids) on livestock farms. Available in 5–36 m³ capacities with Ø2 m and Ø2.70 m diameters, RTM-smooth interior surfaces to prevent bacterial growth, galvanized steel chassis, safety access, and pneumatic or screw loading systems. Targeted at pig, bovine, poultry, and goat farming operations.
• Water Tanks (Cuves à eau) Polyester water storage tanks from 10 to 50 m³ with graduated float gauges, oval man-holes, and DN50 or DN80 butterfly valves. Designed for agricultural and water treatment applications.
• Silos for Agri-Food (Agro-alimentaire) Polyester and composite silos and tanks (5–100 m³) for storing dry bulk food materials such as flour, sugar, and oils. Built with food-grade resins, smooth internal walls for fluid product flow, and high insulation to minimize condensation. Targeted at agri-food manufacturers and processors.
• Water Treatment Tanks (Cuves pour le traitement de l'eau) Cylindrical composite tanks up to 50 m³ for water and effluent treatment, available for above-ground and underground installation. Produced via filament winding to resist earth pressure and external water pressure; configurations include clarifiers, separators with coalescent filters, and storage for liquid fertilizers and hydrocarbons. Targeted at municipal and industrial water treatment operators.
• Industrial Silos (Silos pour l'industrie) Composite material silos (20–36 m³) for storing plastic granules (PP, PE, PVC, ABS, PET), salt, and minerals. Smooth interior walls, high insulation, resistance to wear; configurations include decanter silos, salt silos, and customized units on feet, skirts, or gantries. Compliant with ATEX and EN 13121-3 standards; supports integrated filtration, level detection, explosion safety, online weighing, and pressure relief valves. Metal accessories (stairs, platforms, frames, gantries) available.
• Sub-contracting Composite Manufacturing Services (Sous-traitance) Custom composite manufacturing services including laminated parts (small molds), bespoke composite work (e.g., full van interior fitting), and parts made by filament winding to client specifications. Provides third-party manufacturers access to CIDEX's technical expertise and adaptable production tool without the need to invest in composite manufacturing equipment.
