Airing ducts

The semi circular air ducts are suitable for the ventilation of agricultural products, such as potatoes, onions, carrots and tuberous products.

The semi circular air ducts are made of high quality galvanized sheet steel, which assure a long service life. The air ducts are being manufactured by Tolsma for over 30 years.

Duct length up to 30 metres

TT ventilation ducts are assembled from thirteen different models. This enables total lengths up to 30 metres to be constructed. The AC or EC fans can be placed directly in front of the ventilation canal.

Description

Above-floor channels (air ducts) for vegetable storage

Above-floor channels are made of high-quality galvanized steel. A large range of sizes of modular air ducts allows you to choose a line of the desired length and cross-section. Such ventilation channels can be placed almost anywhere in the premises of the vegetable storage.

The ventilation scheme of the vegetable storage is as follows: from the mixing chamber, the air under the action of pressure fans enters the main air duct, from which the air is supplied to the above-floor distribution channels.

The technology, which includes ventilation ducts for vegetable storage, allows you to increase the height of loading potatoes by more than 4 meters and reduce product losses by 20-25% per year.
