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

  • SafetyClean 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 the 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, increasing your site bio-security by reducing the risk of diseased birds and vermin being attracted to your site. 

    • Prevents waste, saving you money; feed dust can be collected and re-used
    • Improves onsite biosecurity measures, reducing TB and similar diseases
    • 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. 
    • Less evidence of badgers and birds onsite, improving biosecurity
    • Dust collection in the silo ensures a cleaner working environment around the silo
