Silo management system

System integration

The purpose of the XILOMIX® Silo Control is to control and integrate all the functions of one or more silos/closed containers in general while they are being loaded with bulk materials (powder, grain, etc.,) by a pneumatic conveyor. In great detail, the purposes of the system can be summed up as follows:
a) To monitor the pressure inside the silo during product loading to avoid overpressure or underpressure in the silo.
b) To have just one unit control the loading process of several silos meaning we can have a centralised control of the system and the certainty:

- that the truck is connected to the silo, verifying the number of the silo, that has been chosen, and the loading authorization;

- of the condition of the maximum and minimum level gauges,

- that the compressed air pressure is sufficient for cleaning the filter and for feeding the pinch valve,

- of the pressure inside the silo,

- of the loading and simultaneous process status control of 32 silos that can be managed,

- that there is just one power supply for one silo which means a reduction of risks (alarms always need a specific power supply),

- that all the filters will be cleaned automatically at the end of the process.

The XILOMIX® Silo Control system provides:

  • Ease of use;

  • Flexibility;

  • Safety;

  • Reliabilty and reduced maintenance;

  • Installation in already existing plants.


SSE is a synoptic control panel, compact and reliable for storage plants. It is available in two versions:

- SSE32A for handling a single silo (which can be extended to 32 silos by installing 31 SSR01A),

- SSE32B for handling from 1 to 32 silos (installing 1 to 32 SSR01A).

The strong points of the devices described are their simplicity of installation and use.


Components for enhancing the material flow in silos.

SAA, SAB. Aeration pad suitable for tanks and silos used in different industries, in particular in heavy situations or with high temperature. Body in stainless steel AISI 304.

SAD, SAE. Aeration tridimentional disc suitable for tanks and silos used in different industries, in particular where a very good cleaning is necessary.


SUF. Aeration nozzles suitable for small tanks or pipes, easy to mount even on existing equipment.

SAK. Equipment suitable for the regulation, treatment, control of the aerated fluid and used for the connection of the different aerated elements.
