HAS hot gas circulation fans is Effective for hot processes.
Our circulating fans can withstand temperatures of up to 850 °C  and are used for tempering, annealing and hardening, aluminum homojen & aging 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 HAS has proved itself again and again under the toughest conditions. The HAS shaft cooling system prevents the transfer of heat from the furnace through the shaft to the particularly sensitive roller bearings.

The impeller has a special shape and is made of heat-resistant materials to allow high gas flow rates. This ensures that the material in the oven is quickly and evenly heated or cooled. The circulating fan impellers are tempered in the annealing furnace before final machining. This prevents warping when used at high temperatures. The long service life of HAS hot gas circulating fans is well known.

Take advantage of our many years of extensive experience. Getting the correct advice about the system parameters is decisive for the quality of a fan and thus for the reliable operation of your furnace design. Particular care is required in the selection of suitable heat-resistant steels and alloys, and of suitable shaft seals as well as the design of the volute casing and the air-channeling systems in the furnace.
