Upgraded system for silo pressure safety

After the introduction of the SHIELD silo protection system, silo pressure safety company Hycontrol Ltd have announced the launch of the SHIELD Lite SPS, which protects powder storage silos from the dangers caused by excessive pressure during tanker deliveries.

Utilising pressure monitoring and control equipment, SHIELD Lite meets engineering practice and current guidance from the Mineral Products Association. The new 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 behaviour.

Powder storage silos are commonplace in many industries but are at risk of over-pressurisation 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 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 significantly lower than any other system 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 safety components, reducing the need for working at height. Importantly the system is also completely failsafe.
