Two years after introducing the Shield silo protection system, silo pressure safety experts Hycontrol Ltd launches Shield Lite SPS, which protects powder storage silos from the dangers caused by excessive pressure during tanker deliveries.

Utilizing purpose-designed pressure monitoring and control equipment, Shield Lite exceeds best engineering practice and current guidance from the Mineral Products Association. The new, compact panel is designed for simple operation and to be easily understood, giving users a range of new monitoring and diagnostic tools and indicating when the system is suffering from blocked filtration or is being endangered by poor delivery driver behavior. 

Powder storage silos are commonplace in many industries but are at risk of over-pressurization during tanker deliveries. The root causes of this are invariably either driver error resulting in uncontrolled air pressure being discharged during the fill procedure or a failure of the filter venting unit. Pressures from as little as 1 or 2 psi are enough to rupture a silo or blow its filter unit off the top. This poses serious risks, which is why a comprehensive, failsafe safety and control system is vital. 

Shield Lite incorporates essential high-accuracy pressure safety components into a modular design that can be adjusted to suit site requirements. Maintenance is simplified, and the long-term cost of ownership is lower than other systems on the market. Along with many new features, SHIELD incorporates Hycontrol’s ground level testing, in which a single key-turn enacts a full-function test of all the crucial safety components, reducing the need for working at height. Importantly the system is also completely failsafe, a vital feature that’s often overlooked.
