Fast Fire Conveyor Furnace
Muffle-less Conveyor Furnaces for Low-Cost Operation
BTU’s Fast Fire Conveyor Furnace combines the best of both worlds with precision temperature control and low-cost operation.
Whether you’re manufacturing thin-film circuits, passive components, precision resistors, component termination, or many other applications requiring exact atmosphere and temperature control, BTU provides the Fast Fire conveyor furnace system.
BTU’s Fast Fire, due to its muffle-less design, offers reduced power usage by allowing rapid heating and cooling between uses. Further, the design supplies excellent atmosphere flow for binder removal, coupled with precision temperature control to meet the process control needed in thick film firing. In addition to the standard air atmosphere configuration, Fast Fire is available for nitrogen atmosphere operation. For cost-effective high-temperature processing in air or nitrogen Fast Fire is the best choice.
Advantages of Fast Fire’s muffle-less design:
- Short heat-up and cool-down times
- Enables shutting down the furnace on weekends or off shifts.
- No costly muffle replacement
BTU’s Fast Fire furnace was developed with the process rigors of Thick Film processing in mind.
The Fast Fire offers unsurpassed thermal uniformity and the convenience of fast start-up/shut down. These muffle-less systems are typically configured for processing in air, but can also be delivered in a gas-tight configuration for nitrogen process environments.

Atmosphere Control
BTU’s Fast Fire conveyor furnace features precise atmosphere control of the critical process parameters within the furnace. The firing furnace gas panel is designed for ease of use while minimizing operator intervention. Firing section atmosphere is introduced at the cooling section and flows counter to product travel. Process emissions are removed from the process chamber via independent, venturi-driven, exhaust plenum assemblies. The plenum assemblies extend across the entire width of the process chamber for uniform extraction of burnout gases. Entrance and exit gas curtains are provided with top and bottom ratio flow control valves.
Temperature Control
- Left/center/right independent power trim standard on 25″ belt widths
- +/- 2°C across conveyor belt uniformity typical
- +/- 1°C across conveyor belt uniformity achievable in peak zones
