OverviewPlease give us a call for the details on the sizes. Ai CGF1700F series Crystal Growth Furnaces come with swing-open chamber; it also features the famous Kanthal (Sweden) spiral wire coils embedded in 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 by high precision 50-segment Eurotherm 3504 (UK), allowing the user to connect to a PC for remote control and monitoring of the furnace. You can also save or export test results.
Features
Swing-open furnace chamber for fast and easy tube access
Digital multi-segment automatic hoisting control
High precision Eurotherm 3504 PID controller provides optimum thermal process with minimal overshoot
Built-in computer interface
Durable type K thermocouple
Additional thermocouple and Eurotherm temperature display
Safety
Automatic hoisting limit switch
Overheat protection shuts down the furnace if the temperature is outside of the 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.
Warning! NEVER fill the furnace with explosive gases, including Hydrogen, Carbon Monoxide, and Methane.
