Storage - ISO Silo

A new concept for 'on-site' storage of dry bulk materials

The Ultimate Storage and Pneumatic Transfer System

The ISO-Silo is a combined storage silo and pneumatic transfer system designed and supplied for quick installation without the need for foundations.

The ISO-Silo is built within a standard ISO frame which allows transportation by conventional road trailers. It comes complete with a pre-cast concrete base in two sections, which secures the unit in place.

Only three major lifts are involved with its installation. All equipment is at ground level therefore no access to the top of the silo is necessary.

Three external connections are required after installation – electrical supply (single phase), air supply and discharge pipeline. To operate the system an air supply of 2 barg, 340m3/hr volume is required to pressurise the silo and transfer the product to the process feed hopper (s). A separate 7 barg supply is also required (0.002m3/min) for solenoid valve operation.

Once in position the silo is filled by ISO-Veyors™ or conventional road tanker via the inlet pipe which is supplied with a Unicone coupling and automated butterfly valve. On connection the operator performs a one switch operation to allow filling to take place.

On completion of filling, the system then operates automatically by closing the valve on the inlet pipe and opening the air supply valve to pressurise the silo. Once the silo has reached a predetermined pressure (2 barg) and a signal is received from the process hopper/s level control system, the valve on the discharge pipe opens to start product transfer. On receipt of a signal the valve closes and remains so until it receives another signal from the level probe and the top up procedure will be repeated.

Benefits of the ISO-Silo

• Combined storage silo and pneumatic transfer system
• Available in 30ft (37m3) or 40ft (48m3) dimensions
• Designed for rapid mobilisation/de-mobilisation
• No foundations necessary
• No need for access to the top of the silo – all controls at ground level
• Units supplied with integral plc control system
• No planning consent necessary if used as a temporary structure

Once the project comes to a close, the ISO-Silo can be quickly disconnected and disassembled. The concrete base is removed and disposed of and the ISO-Silo is lifted onto a skeletal trailer for transport to the next project or site. All equipment can be used again in the new location.
