Inert Atmosphere Bench Furnace
- Grieve - BAF-8128, BAF-8128-HT, BAF-12128, BAF-12128-HT and more
- Accuracy as percent of controller span
- Uniformity at 100°F below maximum temperature
- Rise Time in minutes to 100°F below maximum temperature
These furnaces are specifically designed for heat treating applications requiring inert atmosphere protection.
Inert atmospheres protect the work from oxidation.
Precision microprocessor based temperature controls and energy-saving insulation maximize the cost efficiency and performance of these rugged units. Ideal for heat treating of tools, dies and other parts.
Operating Characteristics
- Accuracy as percent of controller span
- Uniformity at 100°F below maximum temperature
- Rise Time in minutes to 100°F below maximum temperature
- Tests run with empty oven and minimum exhaust
- Performance will vary with load and application
Certifications
- UL Listed Control Panel
- Meets the Requirements of the Following Standards:
- NFPA 86 (Standard for Ovens and Furnaces)
- NFPA 70 (National Electric Code)
- FM (Factory Mutual)
- OSHA
Caution:
- For use with inert atmospheres only cannot be used with flammable gases
- When processing combustible material fire protection should be considered
Safety Equipment
- Adjustable manual reset excess temperature interlock to turn off heat on malfunction of main temperature controller
- Separate heating element control contactors to turn off heat on malfunction of main control contactors
- Door interlock turns off power to heating elements when door is opened to protect operator from line voltage at heating elements
