Clean Burnout, Precise Control, Reliable Results
Yasui’s RBF Rotating Burnout Furnaces offer uniform heat transfer through the upward convection of precise, temperature-controlled air. By utilizing rotating shelves where the flasks are seated, the RBF system ensures a safe, clean, and perfectly even burnout, eliminating the "cold spots" found in traditional stationary furnaces.
The integrated Variable Power Heating System automatically maintains set temperatures throughout burnout cycles with the utmost precision. With unlimited program slots featuring multiple ramps and holds, Yasui RBF units allow you to create highly tailored burnout cycles for every specific casting application.
Key Features & Benefits
After Burner System
Virtually eliminates noxious smells and fumes associated with antiquated gas and electric furnaces by reaching temperatures above 2.000°F.
Flask Recall System
Automatically brings the required flask forward when entered into the control panel. The narrow door design significantly reduces heat loss while the furnace is open.
Advanced Insulation
Contains intense internal heat while maintaining an exterior surface temperature that is cool to the touch, ensuring a safer workshop environment.
Built-In Dewaxing
Removes injection wax efficiently prior to ramping up furnace temperatures, preventing carbon residue and ensuring a cleaner burnout.
Technical Advantages
- Thermal Uniformity: Rotating shelves ensure every flask receives identical heat exposure.
- Tailored Cycles: Multi-ramp and hold capabilities for complex investment requirements.
- Precision Control: High-accuracy PID monitoring for consistent, repeatable results.
- Eco-Friendly: Integrated afterburner reduces the environmental impact of your foundry.
