The typical error sites make is installing a ‘Frankenstein’ system of general-purpose parts, which are inadequately maintained or tested. Critically, this equipment is unlikely to be failsafe, so when it fails, it goes dangerously unnoticed.
Over-pressurisation is quite simple: primarily a silo safety system failure or a driver error, commonly described as an uncontrolled delivery. The solution to these problems is to monitor and control the delivery. For this, you require a silo protection system, as outlined below.
Monitoring the pressure in the silo means greater control, removing the risk of over-pressurisation. Like any safety-related system, this equipment must be failsafe. An everyday example is a house smoke alarm that beeps when the battery starts to fail, indicating you need to replace it. Unfortunately, most silo systems on the market today are not failsafe.
SHIELD LITE SAFETY SYSTEM
The new SHIELD Lite safety system from Hycontrol is different. It is the only silo pressure safety system on the market that exceeds standards set by the UK MPA (Mineral Products Association).
All the components of SHIELD Lite are entirely failsafe. If the pressure sensor, level probe, PRV or panel has a fault, the system will highlight this so action can be taken before another delivery takes place.
