TF1700cvd.100 is the 1-zone 100 mm OD stationary furnace configuration from Across International's TF1700 Chemical Vapor Deposition (CVD) tube furnace line. The live Across page describes this system as using Mitsubishi (Japan) alumina fiber insulation and molybdenum silicide heating elements inside a double-walled steel housing to help minimize heat loss.

Furnace operation is controlled by a Eurotherm (UK) digital controller with communication port for PC-based remote control and monitoring. Across also notes controller options where the `3204` supports 8 segments and the `3504` supports 50 segments for ramp-and-dwell programming.

Features

• Standard package includes stainless steel vacuum sealing flanges with valves and pressure meter.
• Dual flanges support ensures better sealing and longer tube life.
• Microprocessor-based self-tuning PID control for stable thermal processing with minimal overshoot.
• Built-in ammeter, dual voltmeters, and computer interface.
• Long-life type B thermocouple.

Safety

• Overheat protection shuts the furnace down if temperature is outside the acceptable range or the thermocouple malfunctions.
• Power-failure protection resumes furnace operation from the interruption point once power is restored.
• Across warns never to fill the furnace with explosive gases, including hydrogen, carbon monoxide, and methane.
