Minimise odour emissions and keep rainwater out of your silo

The Alligator tank roof is one of our special products. This cover consists of a taut construction that we produce to size for round silos of concrete, steel or wood. The diameter of the Alligator tank roof can vary from 10 to 32 metres. The tank roof is made up of a wooden column with a crown on which the cloth rests.

The polyester fabric of the Bagtank has been prepared with a high-quality plastic coating. This is resistant to many kinds of mixed slurries, even acidified slurry, and the effects of UV radiation. This ensures a long service life. The seams are welded together using a process known as high-frequency welding. e have designed the shape of the tank roof based on a double-sided curvature, which prevents wind damage. The Alligator tank roof fits perfectly. As a result, rainwater is kept out of the silo and odour emissions are minimised.
