Storage silo design – Spirotech Group Ltd has an outstanding record of designing steel silos for both raw material and liquid storage. We design robust, high-performance silos to suit all types and quantities of material and can design to the specific requirements of your process.

We have designed silos for all the major industries and our experience in the bulk storage market places us as the leading fabricator in this field. Many silos are often designed to fit within confined areas of operating sites, in these cases, jacking construction techniques can be utilised to allow for safe construction at low level.

Versatile silo design to meet your requirements

We can design and develop silos to store everything from foodstuffs and volatile chemicals to fine powders, fibrous materials or cohesive products. In addition, we offer a range of standard silo sizes in carbon steel, stainless steel and aluminium. Our state-of-the-art manufacturing facilities enable us to design and fabricate complete, ready-to-install storage vessels up to 4 metres in diameter.

Larger capacity silo design

Uniquely, we can also design and manufacture much larger silos – up to 15 metres in diameter – in sections for ease of transportation. These site-built silos are assembled into the final storage vessel once on site. They provide a storage capacity of up to 5,000 tonnes.

Our silo design experience allows us to manufacture silos to capacities to suit your needs, from as little as 10m3 up to 2,500m3. All our silos are designed in accordance with the latest BSI, ISO, DIN and VDI standards, where appropriate. We design silos suitable for storing all types of bulk material, including potentially explosive or hazardous products. All silos are designed to be fully compatible with our complete range of dischargers, conveyors and ancillary equipment, such as filters and safety systems.

Our silo design offers a variety of exterior finishes

During the design stage Spirotech’s designers can offer a variety of exterior finishes including stainless steel wrap (either light gauge lapped or heavy gauge all welded), or the lower cost painted carbon steel outer shell. The silo base is a proven and unique design incorporating a series of Z rails that give unequalled support of the base of the product vessel to ensure long life of the entire structure.

Spirotech design a variety of stainless steel silos including:

  • Heat transfer jacket according to the thermal duty and media available (glycol, ammonia, water)
  • Options for electric trace heating for temperature maintenance applications
  • Conventional spray down CIP or specially designed spray-up CIP system
  • Vertical or horizontal agitation
  • Cone bottom skirt supported design (often used in corn syrup or sugar applications)
