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.

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 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.

AVION ULTRA circulating fans – the low-priced ventilation unit without the vibration. ULTRA fans are made of heat-resistant alloy RA 330. ULTRA ventilating fans are always heat treated, x-rayed and examined for smooth operation prior to delivery. The life of the fans of 520 mm and 610 mm may be considerably increased by reduction of the motor revolutions to 750 rpm.

SiSiC radiant tubes offer unsurpassable physical properties, faster heat-up times, longer life, and higher efficiency at competitive prices. An innovation in the radiant tube technology without changing your burners, SiSiC radiant tubes are made of natural raw materials according to a particular process. Their advantages in comparison to conventional tubes made of heat-resistant high-quality steel or monolithic ceramics include durability and reliability at temperatures up to 2450 °F and outstanding resistance against:
