  • j With capacities from 5 to 35 tonnes in 4 different diameters there is a silo that will meet your needs and planning requirements. We always tell our customer, what holds a lot holds a little!
  • j The volume of the silo never alters from manufacturer to manufacturer, however, please bear in mind product densities, feed aeration and fill characteristics affect the amount of pellets your silo will hold so we always recommend you choose a silo with approximately an additional 30% capacity than your required load size. Our sales team will always be able to advise you
  • j A pressure relief valve is incorporated into all silos to protect the silo from damage which can be created from overfilling. Should a silo be overfilled during filling, the valve opens releasing any pressure, protecting the silo from any permanent structural damage
  • j The heavy duty, large radius top sweeping 5mm bend ensures optimum pellet delivery and longevity
  • j The 60° cone provides optimum mass flow for EN plus graded wood pellets
  • j Various alarms; high level, low level, re order level sensors can be integrated into your BMS dependent on your exact requirements
  • j Real time pellet usage can be monitored with silo load cell weighing and can be integrated into the BMS
  • j The AutoVent closes during filling, directing any dust laden air to ground level via the exhaust pipe for discharge of dust to a safe zone
  • j Wood pellet handling can potentially create dust therefore all equipment utilised in these systems have been designed with the flexibility to comply with ATEX and DSEAR guidelines if required. We offer guidance about the inclusion of explosion panels for you to make an informed decision

We provide a range of optional extras to personalise a silo to suit your project needs

From assisting with silo filling, improving feed flow and providing alternative discharge options, Collinson have an optional extra to suit your every need. Here are just a few of the more common solutions which can be chosen to complement your new silo or ordered retrospectively from our Customer Portal.

  • Discharge Options

    There are a range of standard discharge options to suit different applications. Over the years, our range of discharge options has grown and developed so we are able to offer the best solution for every discharge requirement

  • Extension Filler Pipes

    Extension filler pipes allow silos to be sited where vehicular access is restricted. When choosing the site for your silo extension filler pipes allow total flexibility; they are ideal where you simply wish to create a centralised filling point for ease of delivery or in the case of high health sites extension fillers may be utilised so filling of the silos can be undertaken from a perimeter point, removing the need for delivery vehicles to enter the site.

  • Silo Tip

    The SiloTip filling attachment can be incorporated into any County Range silo, increasing versatility with the option of filling the silo using your front end loader or tractor bucket Dependent upon the height and reach of your bucket the SiloTip attachment can be incorporated into any County Range Silo. Great news for existing Collinson customers, SiloTip is available for retrofitting into your existing County Silo

  • Safety Clean Plus

    SafetyClean Plus is an extra discharge from the cone of the silo giving added flexibility to your feeding arrangements by allowing feed to be discharged from the cone of silo whilst also having a main conveyor discharge. All new silos now come with the FloView™safety clean panel as standard giving a reassuring visual check on the feed flow activity inside the silo. Upgrade to the FV-SafetyClean Plus to enable you to draw feed from the gravity discharge should you need to feed by hand in any emergencies. Good news for existing customers, both the FloView and the FloView plus safety clean panel can be retrofitted into existing Collinson Silos.

  • Cyclone Dust Collector

    The Cyclone connects to the silo exhaust via the integrated bend which fits into the exhaust pipe to collects the dust that would normally escape during pneumatic filling, keeping you silo base dust free.

    • Easy to empty - Because the Cyclone is positioned at height, it’s straightforward to empty. Just wheel a barrow underneath, pull the handle to operate the slide, this will release any collected dust for
      later use
    • Space-saving design - the Cyclone stays “out of the way” by mounting on the silo leg. Plus, it utilises the silo's pressure relief valve instead of requiring it's own. 
    • Dust collection in the silo ensures a cleaner working environment around the silo
