SED-655RFX-B — 655 L

Rear-mounted electric tubular heaters warm air, which a high-temperature-tolerant blower circulates through the chamber via dedicated air ducts, ensuring all four sides of the load see uniform hot air. The microcomputer PID controller modulates heater output to hold the set point (RT+10°C to 300°C) within ±1.0°C; an independent over-temperature limit alarm cuts power if deviation exceeds the set band. Timer (1–9,999 min) ends the cycle automatically. 8 cm insulation between cabinet and chamber minimizes heat loss.
