HVTT – High Vacuum Tube Furnaces

The HVTT high vacuum turbo-molecular tube furnaces at 1200°C are available in three standard sizes with a range of tube lengths and diameters available.

Categories: ,


The HVTT high vacuum tube furnaces at 1500°C are available with two work tube diameters. These units are often the starting point for additional customisation such as automated control of gate valves, gas purge, back-fill systems and co-ordinated control of roughing pump with the turbo-molecular high vacuum pump.

  Standard features
•  1200°C & 1500°C maximum operating temperature
•  All controls are mounted within the base unit
•  Access to the work tube is via a removable stainless steel vacuum flange
•  Carbolite Gero 301 digital PID controller with single ramp to set point and process timer
•  Capable of 10-5 mbar vacuum in a clean empty work tube
•  Cooling water failure alarm
•  Heated lengths of 450, 550 or 700 mm
•  Manually operated roughing / backing valve
•  Penning gauge high vacuum monitor
•  Pirani gauge low vacuum monitor
•  Radiation shields at both ends of the work tube maintain uniformity without reducing pump speeds
•  Supplied with work tube inner diameters of 50, 60, 80 mm (HVTT 1200) and 50 and 75 mm (HVTT 1500)
•  Vacuum provided by oil-free scroll pump & turbo-molecular pump
•  Work tube connects to the vacuum system via stainless steel connection

  Options (specify these at time of order)
•  A range of sophisticated digital controllers, multi- segment programmers and data loggers is available. These can be fitted with RS232, RS485 or Ethernet communications
•  Custom built models including a variety of gas backfill systems, automatic & semi-automatic vacuum systems and 3-zone control for improved uniformity is available
•  Over-temperature protection (recommended to protect valuable contents & for unattended operation)
