Biogas tank

(please see brochure)

We supply insulated biogas tanks in sizes from 500 - approx. 9000 m³ in galvanized, stainless steel, vitreous enamelled or mild steel - or a combination of these materials. Please see sizes

As design and manufacturing of the tanks, nozzles and any other equipment takes place centrally in Assentoft, we are able to provide a quality product at a very competitive price.

The tanks are designed according to Eurocodes - and come with a comprehensive statical report.

Assentoft Silo has a patent pending on a sand washer for continuous removal of sand from an operating biogas plant.


We advise our customers about design of the tanks - and prepare 3D drawings according to customer's wish (including demands re. dimensions of tanks, pressure, temperature, snow load, wind load, location of nozzles etc.)

By choosing Assentoft Silo as you biogas tank supplier, you benefit from our more than 25 years of experience within the biogas industry. Our first reactor tank was supplied in 1988 (please see references).

The tanks are suitable for center stirrer, side fitted stirrer or Gas mix. The tanks are supplied with the requested equipment to suit the desired stirring system.

Angle irons, ladders, platforms, railings, nozzles, flanges etc. are produced at our own factory at our sister company, Åbybro Maskinfabrik A/S. All according to customer wish - and in all sizes.

Flanges are welded on to pipes and bendings, galvanized or sandblasted - and coated in our own painting facilities.

Electrical control is designed and produced at our own electrical department.

The steel sheets for the tanks are bought directly at the steel production facilities.
