Hot Gas Circulation Fans

Our circulating fans can withstand temperatures of up to 1,000°C and are used for tempering, annealing and hardening furnaces, as well as for core drying. To operate the furnace system economically an even and fast exchange of heat is required. The air cooling system used by Venti Oelde has proved itself again and again under the toughest conditions. The Venti Oelde Duplo shaft cooling system prevents the transfer of heat from the furnace through the shaft to the particularly sensitive roller bearings.
