THE PROBLEM
Whilst this valve had been signed off as 'inspected' by a silo engineer, the birds' nest underneath the lid would suggest otherwise!
THE SOLUTION
Effective inspections by trained engineers will avoid this.
THE PROBLEM
This pressure sensor has been severely damaged and will certainly not be providing adequate monitoring of the silo during a fill.
THE SOLUTION
Regular inspections and effective maintenance will avoid this.
THE PROBLEM
Powder is blowing out of this belly silo filter during the filling process as the result of excessive internal pressure build-up.
THE SOLUTION
Regular inspections and effective maintenance will avoid this.
THE PROBLEM
This filter's cartridges have been blinded with product meaning pressurised air cannot escape. Serious damage to the silo can result.
THE SOLUTION
SPS pressure monitoring and regular inspections will avoid this.
THE PROBLEM
There is a PRV somewhere! It appears that no effective servicing has been carried out for months or years. The safety system is compromised.
THE SOLUTION
A testable SPS which will alert users if the PRV is blocked.
THE PROBLEM
These filter cartridges are completely blocked. This can result in environmental pollution and could cause serious damage to the silo.
THE SOLUTION
SPS pressure monitoring and regular silo servicing will avoid this.
THE PROBLEM
Visually, this PRV appeared fine - until the lid was lifted to reveal a solidified mess. The silo safety system has failed.
THE SOLUTION
Effective servicing will ensure this can't happen.
THE PROBLEM
The solidified material underneath this filter housing indicates all is not well. The silo protection system is likely 100% ineffective.
THE SOLUTION
Regular servicing and a testable SPS will solve this.
THE PROBLEM
This PRV appeared fine until the lid was lifted to reveal a solidified mess. This leakage indicates the silo safety system has failed.
THE SOLUTION
A testable SPS which will alert users if the PRV is blocked.
THE PROBLEM
This PRV has been completely blocked with cement that has solidified, and has no chance of working if needed.
THE SOLUTION
A testable SPS and effective servicing will help avoid this.
THE PROBLEM
Blocked filter cartridges will cause pollution if they burst, or if completely blocked may damage the silo.
THE SOLUTION
SPS pressure monitoring and regular silo servicing will avoid this.
THE PROBLEM
This blocked filter unit was blown off the silo roof by pressure build-up in the silo. A member of staff was injured.
THE SOLUTION
SPS pressure monitoring and regular silo servicing will avoid this.
THE PROBLEM
This PRV was replaced only a year earlier due to blockage, but the issue remains.
THE SOLUTION
Regular, effective servicing and a testable system will help avoid this.
THE PROBLEM
Solidified product around and inside this PRV suggests the safety system has failed.
THE SOLUTION
Effective silo protection helps by providing early warnings to avoid this.
THE PROBLEM
The filters in this unit have become damaged, allowing the product to escape and completely block it.
THE SOLUTION
Regular silo servicing and effective SPS pressure monitoring will help avoid this.
THE PROBLEM
Escaped product has completely solidified, encasing all the safety equipment!
THE SOLUTION
A testable SPS and effective servicing will help avoid this.
THE PROBLEM
Solidified product around this pressure relief valve suggests a failure of the silo protection system.
THE SOLUTION
Effective silo protection should mean the PRV never vents product!
THE PROBLEM
This PRV appeared fine until the lid was lifted – this indicates the silo safety system has failed.
THE SOLUTION
A testable SPS and effective servicing will help avoid this.
THE PROBLEM
Aggressive product has destroyed this inlet valve, putting the silo at pressure risk during filling.
THE SOLUTION
Regular, competent servicing will identify problems like this early.
THE PROBLEM
Product has blown out of this PRV and solidified, blocking it up. It certainly will not work if required!
THE SOLUTION
A testable SPS and effective servicing will help avoid this.
THE PROBLEM
Unmonitored, uncontrolled inlet pressure during filling procedure risks rapidly over-pressurising a silo.
THE SOLUTION
SPS with a pressure sensor-controlled auto shut-off valve will avoid this.
THE PROBLEM
This air vent filter cartridge has become blinded with powder, meaning pressurised air cannot escape.
THE SOLUTION
SPS pressure monitoring and regular silo servicing will avoid this.
THE PROBLEM
Lifting the lid revealed this the PRV on SPS was completely blocked with solidified product.
THE SOLUTION
A testable SPS which will alert users if the PRV is blocked.
THE PROBLEM
Blown-out product around the PRV is a common indicator of serious issues with silo pressure.
THE SOLUTION
Competent servicing and a testable SPS will stop this.
THE PROBLEM
This silo shows clear signs of buckling from over-pressurisation caused by an ineffective SPS.
THE SOLUTION
A well-maintained, testable SPS which will alert users if the PRV is blocked.
THE PROBLEM
The release of powder during filling is a clear sign of a major problem with the silo protection system.
THE SOLUTION
A well-maintained, testable SPS which will alert users if the PRV is blocked.
THE PROBLEM
Product on top of the silo is a clear sign of poor maintenance and issues with the PRV or filter.
THE SOLUTION
A well-maintained, testable SPS which will alert users if the PRV is blocked.
THE PROBLEM
This shaker unit was ineffective in cleaning itself due to poor monitoring and maintenance.
THE SOLUTION
SPS pressure monitoring and regular silo servicing will avoid this.
