Cyclone Box Furnace

The rapid, uniform heating of the Cyclone Box Furnace has been proven in thousands of installations. The work is brought rapidly to temperature by the unique recirculating convection heating system that forces pressurized air through the load at high velocity. Temperature uniformity is typically ±10°F or better. Overheating by direct radiant heat is avoided because the heat source is in a separate chamber. This cyclone box furnace can be used for a variety of applications but is ideal for tempering.
