CUSTOMER : One of the leaders in the chemical industry in Germany
PROBLEM : Arch clogging in a silo with a capacity of 9000 m3 (20 m high, 6m diameter). Approximately 15% of the material stored was clogged.
PRODUCT : Sodium carbonate
OBJECTIVE : Empty the silo in order to recover 100% of the storage capacity.
SOLUTION : – First stage: Use of pneumatic POWERNET to create a chimney with a diameter of 350 mm.
– Second stage: Intervention by pneumatic GIRONET and efficiently clean the whole of the silo
RESULT : The customer recovered all of its storage capacity. Production was not stopped and the intervention took place in complete safety and without human intervention inside the storage unit.
CUSTOMER : Food-processing plant
PROBLEM : Following a fire in 2 hoppers, condensation formed, causing substantial caking.
PRODUCT : Rice flour
OBJECTIVE : Stop the caking without having to use rope access technicians.
SOLUTION : – First stage: piercing of an arch using POWERNET
 Second stage: Intervention by GIRONET to stop clogging.
RESULT : The hoppers were completely cleaned without having to use a team of rope access technicians.
