Better protect grain stored in the silos against pests, this is what Boge offers with BlueProtect.

This solution consists in injecting into the grain silos a gaseous mixture of almost pure nitrogen with a maximum of 1% of residual oxygen. Nitrogen then takes the place of oxygen and thus deprives the pests and oxygen-dependent fungi of their livelihoods.

At the same time, the amount of breathing losses is decreasing, as is the risk of smoldering fire. For its BlueProtect solution, Boge uses nitrogen from the ambient air. Near the silo, a compressor generates compressed air. This air passes through a dryer and a combined filter to a membrane filter that separates the nitrogen (N2) from the oxygen (O2) before conducting it into the silo. BlueProtect is therefore an effective pest control method for all sectors where the use of chemical agents is not allowed or desired, for example in organic farming or in the breweries.

Boge has all the components of the plant in a single container so that BlueProtect can be used flexibly in space, with no special prior knowledge and different types of silos. In order to determine nitrogen requirements in advance, the supplier analyzes the initial situation with the manufacturer. The presence of a sufficiently dense silo is a basic prerequisite. To test the solution, Boge provides a rental container on demand to clearly determine the tightness of the silo after a few days.
