Equipment and spare parts - Silo safety system

MARPO offers a delivery of silo safety system for the safeguarding of silo from damages caused by overfilling or excess pressurization inside the silo.

The silo safety system is advisable when the silo filling process takes place without operator's visual supervision or if required by local safety rules.

The system prevents both overfilling and excess pressurization by pressure detection inside the silo and maximum level indicator.

Silo safety system Main components of the system:

  • electromechanical pressure meters,
  • electro - pneumatic cut-off valve,
  • maximum level indicator,
  • tanker coupling with sensors,
  • power unit (placed near silos) IP65 (box equipped with buttons and signal lamps),
  • box with pneumatic equipment,
  • audible alarm indicating the maximum level of material,
  • pressure relief valve,
  • control panel placed in batching plant control room,
  • electrical equipment and other accessories.


The silo safety system controls the silo filling process and prevents overfilling or starting the filling operation without operator's presence.

ADVANTAGES OF SILO SAFETY SYSTEM:

  • monitoring of the values of: pressure inside silo, material's level, compressed air in pinch valve,
  • improving the ecological standard of installation (reduces dust emission into the atmosphere),
  • fully automatic de-dusting system,
  • eliminating the possibility of filling the wrong silo
  • indication from electronic pressure meter about risks,
  • reduction of risk of silo damaging
  • smaller compressed air consumption for filters regeneration.
