At Thermic Edge, we pride ourselves on being at the forefront of the vacuum furnace industry. Providing a complete service, our bespoke versatile ranges gives you the tools necessary for any application.
Laboratory Vacuum Furnaces with Tungsten crucible or flat sample hot zones for thermal processing, heat treatment, annealing & vacuum sintering in Vacuum, Nitrogen or Hydrogen environments.
Thermic Edge laboratory vacuum furnaces offer a range of Tungsten hot zones to suit a variety of uses. Using the same set up as the graphite furnaces the Tungsten furnace range has an ultimate vacuum of 5×10 ̄²mBar whilst able to operate at atmospheric pressure in an inert atmosphere.
Tungsten crucible furnaces are also available using mesh style elements in two sizes:
2000°c Large Laboratory Vacuum Furnace with Tungsten Hot Zone Crucible Furnace, 5kW DC PSU.
Tungsten Hot Zone – Ø150 x 75mm
2000°c Extra Large Laboratory Vacuum Furnace with Tungsten Hot Zone Crucible Furnace, 20kW DC PSU.
Graphite Hot Zone – Ø80 x 140mm
4” Tungsten Hot Zone, 5kW DC PSU
6” Tungsten Hot Zone, 10kW DC PSU
8” Tungsten Hot Zone, 15kW DC PSU
The Tungsten Laboratory Vacuum furnaces are available with either crucible or wafer sample heating. For wafer sample heating a simple flat element is housed in a Tungsten body with radial heat shielding. For crucible heating the hot zone is heated using a Tungsten Mesh element with heat shield provided by Tungsten foil sheets.
Thermic Edge’s range of laboratory vacuum furnaces provide a user-friendly interface promoting their ease of use via modern touchscreen HMI display which allows control of all furnace pumping, gas processing and venting features. With multiple screens for operation, interlock displays and valve states.
The HMI allows the user to control the automated pump down sequence which is designed to remove residual oxygen from the chamber and intern increasing the life of the hot zone and avoiding the possibility of oxidation occurring.
Two independent gas inputs are also controlled via the arm mounted HMI with their individual flows manually adjusted to the user’s requirements. Pumping speeds are also regulated manually via a Speedi valve mounted on the front of the vacuum furnace.
Temperature and datalogging are controlled via a Eurotherm Nanodac PID temperature controller / data logger which can be connected to a remote PC for data analysis. Software is provided to allow for multi-step process cycles to be programmed allowing for simple repeat testing and easy adjustment to programs.
The fully water-cooled vacuum chamber and power feedthroughs keep the exterior of the chamber at ambient temperature and preventing overheating, allowing for extended periods of operation.
All laboratory vacuum furnaces require a 3 phase electrical supply, chilled water supply and drain, Argon gas for venting, process gas supplies and exhaust line.
