Cyclone Gas-Fired Pit Furnace

CYCLONE gas-fired pit furnaces are capable of temperatures up to 1250°F (1400°F optional). The furnaces have a separate heating/fan chamber that provides heat to the work chamber. The workload is heated when the supply gas is burned in the heating chamber then pressurized by a rapidly circulating fan. Pressure above the load, and suction below, force the heated gases through the load at high velocity with minimal temperature drop. Excess volume is forced out through a flue after passing through the work. Cycle time is minimized by rapid heat up rates. Heavy, dense loads may be uniformly treated, maximizing throughput. Temperature uniformity is typically ± 10°F; when specific fixturing is used, ± 5°F can be attained.

Loading the Cyclone pit furnace is virtually foolproof. Because the fan and burner nozzle are separate from the load chamber, damage from accidental contact is eliminated. The entire work chamber is metal-lined for maximum durability.

The Cyclone is designed for convenient maintenance. The fan motor is externally accessible for easy service and replacement.
