Description

The SYVRAC Orthophthalic Rigid Silos are designed for the outdoor storage of powdery or granular products under optimal economic conditions. They represent a perfectly suitable alternative for industries seeking a reliable solution without the extreme chemical resistance required for isophthalic silos.

Structure & Materials

Manufactured from orthophthalic polyester resin reinforced with fiberglass, these silos are molded in a single block without welds, ensuring leak-tight storage and long service life. An exterior gel coat provides protection against UV rays and weather conditions.

Typical Applications

The orthophthalic silo is particularly suited for:

  • Plastics industry (storage of plastic granules, PVC, PE, PET…)
  • Food industry (cereals, seeds, flour, sugar…)
  • Light chemical industry (mineral fillers, carbonates…)
  • Construction materials (plaster, cement, lime…)

Technical Features

Orthophthalic resin provides sufficient resistance for chemically mild products at an optimized manufacturing cost. This type of silo should be favored when the chemical constraints do not require the use of isophthalic or vinyl ester resin.

Easy Installation

Thanks to their lightweight design compared to steel silos, orthophthalic silos are easy to transport and quick to install. They are directly installed on concrete pads, with or without a support structure.

Full Customization

Each silo is custom-designed according to the nature of the stored product, discharge flow rates, available height, and site constraints. Options for fluidization, dust removal, weighing, and ATEX safety systems can be integrated as needed for the process.

1 • One-piece Orthophthalic Resin Shell

The silo body is made of orthophthalic resin reinforced with fiberglass, ensuring high rigidity and perfect leak-tightness without welding. Its lightweight design makes on-site installation easier.

2 • Anti-UV Exterior Treatment

The exterior gel coat applied to the shell protects the structure against aging caused by UV rays and weather conditions, ensuring a lifespan of over 25 years in outdoor environments.

The dome is equipped with a pneumatic filling port, pressure relief valves, dust collection filters, and access hatches for inspection.

3 • Secured Filling Dome

The dome is equipped with a pneumatic filling inlet, pressure relief valves, dust filtration systems, and access hatches for inspection.

4 • High-Slope Conical Bottom

The 60° discharge cone promotes gravity flow even for low-flowability powders. Fluidization systems can be added for materials prone to clogging.

The 60° discharge cone promotes gravity flow even for low-flowability powders. Fluidization systems can be added for cohesive or bridging products.
The silo is supported by a galvanized steel structure designed according to Eurocode standards to ensure stability and resistance to wind and seismic loads.

5 • Galvanized Metal Supports

The silo rests on a galvanized steel structure designed according to Eurocode standards to ensure stability and resistance to wind and seismic loads.

Options

Each of our resin silos is standard; the available options allow us to customize them according to your needs and requirements.
