Renewed air ducts

21 July 2021

You can’t have failed to notice it – the media are full of it: “Supplies and prices of building materials are under great pressure”.

In order to have more control over this situation, we have chosen a new supplier of plate material for the Tolsma-Grisnich ventilation ducts.

We now have our own production line for the wave profile. High-strength steel was chosen for this. This type of steel has the advantage that it is lighter while maintaining its load-bearing capacity.

This high-strength steel is the basis for the Tolsma-Grisnich ventilation ducts. Ventilation ducts are an important link in a ventilation system. The air is distributed evenly throughout the batch via a ventilation duct.

The TT ventilation ducts are made up of thirteen different types. This has the advantage that it offers the possibility to create a total duct length of 30 meters. The ventilation ducts can be placed directly in front of a fan or used in a pressure chamber arrangement.

Be assured of an even air distribution in your batch of potatoes or onions and order your ventilation ducts on time.
