Optional features:

  • Digital programmable temperature controller with two or more programs of 8 steps (ramp and soak) per program or totally 16 steps
  • Digital programmable temperature controller with 10 programs of 100 steps (ramp and soak) per program, and USB port for process control through friendly user interface and documentation with supplied freeware
  • Inverter power drive
  • Manual gas supply system for inert, reductive and oxidizing atmosphere development in heating chamber
  • Chimney for hot flue gas or smoke ventilation
  • Side opening door

Dryers

Dryers are designed for quick and homogenous drying, as they are equipped with rear mounted fun that enhances convective heating and drying of samples. This feature ensures temperature uniformity and high drying rates. This furnace can be manufactured in various sizes and equipped with several extra features.

Standard features:

  • Maximum working temperature 250 °C
  • Controllable air feeding rate
  • Digital dual screen PID temperature controller
  • INOX for inner lining, durable steel for outer lining
  • Three standard sizes: 90 lit (500x480x400 HXWXD), 120 lit (600x480x400), 210 lit (700x600x500)

Optional features:

  • Custom sized chamber shape and volume

This is a general purpose furnace for a wide range of applications. Maximum furnace temperature ranges from 1200 to 1800 °C, while chamber size and geometry are custom-made. Various features can be fitted to the standard version in order to extend the furnace utilities.

Standard features:

  • Maximum working temperature 1200, 1600 and 1800 °C
  • Digital dual screen PID temperature controller
  • Molybdenum disilicide MoSi2 (for 1600 and 1800 °C models) and aluchrom heating elements for long life and consistent performance.
  • System for continuous cooling of heating elements connectors
  • Compact multilayer layout of low thermal mass and ultra-high purity alumina insulation
  • Inverter power drive (1600 and 1800 °C models)
  • Flap down or side opening door
  • Chimney for hot flue gas or smoke ventilation

Optional features:

  • Custom sized chamber volume and geometry
  • Digital programmable temperature controller with recallable 10 programs of 100 steps (ramp and soak) per program with USB port for process control through friendly user interface and documentation with supplied freeware
  • Analog or digital gas supply system for inert, reductive and oxidizing atmosphere development
  • Controllable heating chamber cooling through automatic air supply system for dramatic reduction of thermal cycle time
  • Aperture with quartz glass for optical observation of sample heating
  • Protection from overheating through independent safety circuit

Tube furnaces

When small samples’ heating is required, tube furnace constitutes the best choice. Thermawatt tube furnaces are reliable, exhibiting high temperature stability and large isothermal region. Heating is provided by wired resistance element arranged along the tube. Maximum working temperature can reach 1200 °C. The inner tube diameter can range from 25 mm to 110 mm and the length to 1500 mm. In other occasions the temperature can reach 1500 °C.

Standard features:

  • Maximum working temperature 1200 °C
  • Digital dual screen PID temperature controller
  • Working tube made of high purity alumina
  • Solid State Relay for silent operation
  • Working tube diameter and length are customized
  • Durable steel outer shell

Optional features:

  • Digital programmable temperature controller with 10 recallable programs of 100 steps (ramp and soak) per program. Controller comes with USB port and can be connected with pc for process control through user-friendly graphic interface and documentation with supplied freeware
  • Special taps can be supplied so as to reduce heat losses from work tube ends and improve temperature uniformity
  • Plugs for special atmosphere development in the working tube (reductive, oxidizing or inert gases)
  • Build-in gas supply system for gas flow regulation. It includes flowmeter, flow regulator and air-trap
  • Inverter power drive
  • Mechanism for working tube rotation by 90 degrees (from horizontal to vertical position)

Multi-zone tube furnace

This is a horizontal tubular furnace with three or more heating zones, located along the heating tube which can be set independently. This set-up is essential when temperature uniformity along the heated tube is required, or when gradation of temperature along the tube is desired.

Standard features:

  • Maximum working temperature 1200 or 1500 °C
  • 3 heating zones of equal length
  • Digital dual screen PID temperature controllers
  • Working tube made of high purity alumina
  • Durable steel outer shell
  • Solid State Relay for silent operation

Optional features:

  • Special taps can be supplied so as to reduce heat losses from work tube ends and improve temperature uniformity
  • Plugs for special atmosphere development in the working tube (reductive, oxidizing or inert gases)
  • Build-in gas supply system for gas flow regulation system that includes flowmeter, flow regulator and air-trap

Vacuum tube furnace

This type of single or multi-zones horizontal tube furnace is equipped with proper system for vacuum application inside the tube. For this purpose, the system comes with a build-in vacuum pump for better than 10-3 mbar with clean empty work tube, and plugs for tube sealing purposes. Standard and optional features of this model coincide with those of tube and multi-zones tube furnaces.
