Airtight Grain Silos

Tunetanken Airtight Grain Silos ensure best possible conditions for storage of grain and harvest. Airtight Grain Silos maintain the quality of the grain high. In an airtight silo the grain lose their germination capacity and thus have a preservative and fermenting effect. Our high-tech Airtight Grain Silos provide the most cost-effective storage, as you avoid the extra costs of drying. In an airtight silo, the risk of vermin is minimised as there is no atmospheric oxygen present.

Our Airtight Grain Silos can be built according to your specific needs, e.g. in relation to filling and emptying equipment, dimensions, connection to other silos as well as colour choices. This ensures that Tunetanken Airtight Grain Silos fit into the new surroundings as well as for your workflow.

Airtight Grain Silos are made of fiber-reinforced polyester and have smooth inner surfaces, which facilitate cleaning and ensure optimal flow during the grain extraction.

Our Airtight Grain Silos are your guarantee for a Danish-made quality, which is based on almost 50 years of experience as well as the latest development within composite materials. Tunetanken Airtight Grain Silos give you the best utilization of your production while maintaining the good grain quality.
