Ai RTF1200Ā series top-open tube furnaces feature the famousĀ KanthalĀ (Sweden) spiral wire coils embedded inĀ Mitsubishi (Japan) high-quality grade 1500 alumina fiber insulation. A double-walled steel internal housing helps minimize heat loss to the exterior surface.
Furnace operation is controlled byĀ Eurotherm (UK) multi-segment digital controller, allowing the user to connect to a PC for remote control and monitoring of the furnace.
Ā
Controller Options:Ā
Eurotherm 3504: 50 segments (ramping and dwelling)
Features
- Top-open furnace chamber for fast and easy tube access.
- Standard package includes set of stainless steel vacuum sealing flanges with valves and pressure meter.
- Eurotherm microprocessor based self-tuning PID controller provides optimum thermal process with minimal overshoot.
- Built-in ammeter and dual voltmeters for easy monitoring and troubleshooting.
- Built-in computer interface.
Ā
Safety
- Overheat protection shuts down the furnace if temperature is outside of acceptable range (refer to controller's manual) or when the thermocouple is broken or malfunctions.
- Power failure protection resumes furnace operation right after the point of failure when power is reestablished.
- Limit switch turns off furnace once top is open.
Ā
Warning! NEVER fill furnace with explosive gases, including Hydrogen, Carbon Monoxide and Methane.
