- One-touch digital control stores six (6) menu presets and lets you lock settings, flip belt direction, or toggle °F/°C at any time.
- Tool-less cleaning—front panel, conveyor, fingers and baffles lift out in seconds.
- Built to last with an all-stainless exterior, stainless bake chamber and brushless DC drive motor.
- Factory paid start-up by an authorized tech protects your investment and warranty (registration required).
