Avion Manufacturing

AVION MFG. is a supplier of radiant tube inserts made of Silicon-Carbide. The patented twisted “Y” design produces non-turbulent high convection flow. The subsequent radiated heat from the SpyroCor™ results in the highest rate of uniform heat transfer possible. In a traditional radiant tube, 45% more energy is released in the burner leg than the exhaust leg due to the highly luminous flame. Both radiation and convection heat transfer are present in the burner leg. The hot gases in the exhaust leg have an emissivity of less than .05. Thus, convection heat transfer is dominant in the exhaust leg. To Save Fuel, SpyroCors™, with an emissivity of .95, are installed in the last 23’s of the exhaust leg. Radiation and convection heat transfer are now present. The exhaust leg and burner leg are now balanced from a heat transfer standpoint. Input into the radiant tube burner is reduced by 20%. Energy available to the load is maintained.

n the CYCLONIC burner tip design, the drill holes are shaped in an angled fashion to produce a helical flame pattern. The swirling motion heats the radiant tube more efficiently and heat accumulation at single points is reduced; this provides more uniform heat distribution and better tube life. Additional flame breakers are no longer necessary and consequently subsequent costs are avoided! By improved design the CYCLONIC burner tip increases the heat efficiency of the burners by at least 10 %; with adjustment an improvement of more than 25% is possible. By using the highly heat-resistant high-grade steel RA 330 the resistance of the CYCLONIC burner tip against oxidization is quadrupled in comparison with other products and the melting point is higher.

AVION SC Fans are made of heat resistant alloy HUCB. SC Ventilating Fans are heat treated, x-rayed and balanced dynamically for smooth operation prior to delivery. SC furnace rollers are made of HK alloy, to provide excellent wear resistance as well as essential heat resistance. Rollers are well balanced and aligned for smooth operation on the loading cart or in the furnace.

Combined heat conduction, protection and insulation lining for vacuum furnaces Graphite Insulation is a newly developed composite material made of the most modern graphite materials, combining the advantages of graphite insulation and armouring in one easy to handle board. By means of a specially developed crystal welding process, both materials are joined. More expensive CFC boards can be replaced economically. The Advantages of Graphite Insulation are: Possible energy reduction of 20% by reduced heating and cooling intervals High mechanical protection with high insulation properties Reduction of lining intervals No reduction of insulation properties after damage of robust protective layer Considerable reduction of dusting Easy assembly, simply cut with standard wood-working tools One board = triple effect Available in 24" x 47" and 40" x 60", as well as 1", 1.5", and 2" thickness Maintenance of the insulation properties continues even after damage – look at the example to the right of 500 cycles after damage by a forklift truck.
