High Vacuum Tube Furnace – HVTT

The HVTT high vacuum turbo-molecular tube furnaces are available in three standard sizes. A range of tube lengths and diameters is available.

The HVTT high vacuum tube furnaces at 1500 °C are available with two work tube diameters.

These high vacuum furnaces 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 or 1500°C maximum operating temperature
  • Capable of 10-5 mbar vacuum in a clean empty work tube
    Supplied with work tube inner diameters of 50, 60 and 80 mm (HVTT 12) or 50 and 75 mm (HVTT 15)
  • Heated lengths of 450, 550 mm or 700 mm
  • Vacuum provided by oil-free scroll pump & turbo-molecular pump
  • Cooling water failure alarm
  • Manually operated roughing / backing valve
  • Pirani gauge low vacuum monitor
  • Penning gauge high vacuum monitor
  • Work tube connects to the vacuum system via stainless steel connection
  • Access to the work tube is via a removable stainless steel vacuum flange
  • Radiation shields at both ends of the work tube maintain uniformity without reducing pump speeds
  • All controls are mounted within the base unit

Options (specify these at time of order)

  • Over-temperature protection (recommended to protect valuable contents & for unattended operation)
  • A range of sophisticated digital controllers, multi-segment programmers and data loggers is available. These can be fitted with RS232, RS485 or Ethernet communications
