What tank aluminum cover does

Tank Aluminum Cover, S.L. (TAC, trading as TAC Enviro) is a privately held Spanish engineering and manufacturing company headquartered in Seville, Spain, founded in 2005. The company designs, manufactures, and installs equipment for industrial storage tanks serving the petrochemical, water, and energy sectors. Its product portfolio is organized around four core lines — TankDome (aluminum geodesic dome roofs), TankPontoon (internal floating roofs), TankContact (hermetic full-contact floating roofs), and TankSeal (primary, secondary, double, and tertiary sealing systems) — supported by six auxiliary modules including TankDrain, TankSuction, TankBaffle, TankCorr, TankCover, and Tank Oil Skimmer. Products are engineered to comply with API 650, EUROCODE, and NFPA standards, with construction based on aluminum for lightweight, self-supporting, corrosion-resistant structures designed to reduce VOC emissions, prevent product evaporation, and extend tank service life.

TAC's technology centers on custom-engineered aluminum structures: geodesic domes using triangular I-beam geometry to distribute stress without internal columns, modular floating roofs with interconnecting grid pontoons, and a comprehensive seal range (mechanical, tube, pantograph, and compression-plate designs). Installation is offered without operational interruption for retrofit projects, addressing a key constraint for refinery and terminal operators. The company employs classical structural engineering methods, including matrix and finite element calculations, rather than software or AI-driven approaches.

The business model is direct B2B enterprise sales of custom-engineered capital equipment, priced per quote and typically contracted as multi-year project agreements. Revenue is generated from one-time equipment sales plus accompanying installation and technical services. TAC operates dedicated regional sales contacts across Europe, North America, South America, Africa, and Asia, with no channel-partner or reseller network indicated. The customer base consists of large enterprise accounts — primarily global oil majors and national oil companies — and TAC has received Spanish and European institutional support through ICEX-Next, ERDF, and NextGenerationEU programs.

Products and services

• TankDome Geodesic aluminum dome for industrial storage tanks that reduces vapor emissions, prevents water ingress, withstands extreme environmental conditions, and extends tank life with low maintenance. Self-supporting hemispherical structure without internal columns, compliant with API 650 and EUROCODE standards.
• TankPontoon Internal floating roof system designed to protect liquid products from evaporation, featuring an interconnecting grid structure with high strength-to-weight ratio. Configurable in aluminum or stainless steel.
• TankContact Hermetic full-contact floating roof system that completely seals the tank top space, eliminating evaporation and significantly reducing vapor emissions through modular panels that make direct contact with the stored product. Conforms to API 650 Appendix H and installs through manhole access.
• TankSeal Comprehensive range of sealing solutions including primary, secondary, double, and tertiary seals (MS6 Mechanical, TB5 Tubeseal, PT1 Pantograph, CPL5, CPP, CPI, CPU, DL5 compression plate) and internal screen seals (MSH Mini-Shoe, DLT Delta, GVR Graver) and WPR Wiper secondary seal for external and internal floating roof tanks.
• Tank Oil Skimmer Floating intake system with adjustable filter designed to mechanically separate two immiscible liquids without altering fluid properties. Compatible with all floating roof types and tank sizes. Available in aluminum, steel, and stainless steel with various seal options.
• TankDrain Drainage system for floating roofs that prevents rainwater accumulation and protects stored product integrity. Built with polyamide and ECTFE reinforced with stainless steel. Compatible with API-650, NFPA, and EUROCODE standards. Available in 3-inch, 4-inch, 6-inch, and 8-inch sizes.
• TankSuction Floating suction system designed to efficiently extract product accumulated on the surface of stored liquid. Withstands temperatures from -15C to 80C and pressures up to 1 bar (tested at 3 bar). Flow rate up to 2 m/s. Compatible with API-650.
• TankBaffle Internal barrier screen system for optimizing fluid guidance in water installations such as sand traps and decanters. Modular design with omega profiles for easy wall adaptation. Compliant with European standards with matrix and finite element calculation options.
• TankCorr Self-supporting protection covers for water installations such as sand traps and decanters, designed to minimize gas and odor accumulation. Corrosion-resistant construction. Compliant with EUROCODE 1 and 9.
