Hycontrol’s updated SHIELD Lite silo protection system is the most advanced SPS on the market today and results from decades of silo pressure technology development, experience and expertise. A proven, failsafe solution to silo over-pressurisation, it has a compact, all-in-one design that retrofits to almost any silo. This new model is even simpler to install and operate; the silo-top unit ships pre-wired with the level probe, pressure sensor, and PRV test mechanism already installed. The best silo protection system just got better.

Using purpose-designed, state-of-the-art pressure monitoring and control equipment, SHIELD Lite meets and exceeds best engineering practices and 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 endangered by poor delivery driver behaviour.

Powder storage silos are commonplace in many industries but risk over-pressurisation during tanker deliveries. The root causes of this are invariably either driver error resulting in uncontrolled air pressure being discharged during the filling 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 factor poses serious risks, which is why a comprehensive, failsafe safety and control system is vital.

System 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 Lite incorporates Hycontrol’s pioneering Ground Level Testing system, in which a single key-turn enacts a full-function test of all the crucial safety components, dramatically reducing the need for working at height. Importantly the system is also wholly failsafe, a vital but often overlooked feature. The system can now even inform users if there has been an attempt to override the inlet safety valve.
