• Maximum operating temperature range up to 1800°C.
• Depending upon application, a tube furnace can be designed in many sizes and shapes; most commonly these units are classified as Horizontal Tube Furnace, Vertical Tube Furnace, Horizontal split Tube Furnace, Vertical split Tube Furnace, Muffle Cum Tube Furnace.
• Capable of 10-5 mbar vacuum in a clean empty work tube.
• Compact design for minimum space requirement.
• Rugged and durable Construction.
• Outer casing is made up thick mild steel with duly powder coated or thick buffed stainless steel, gives long service life with extremely resistant.
• Multilayer insulation with vacuum formed ceramic fibre or refractory bricks with low thermal mass.
• High Purity Alumina/Quartz/Metal tube with two fibre plugs included.
• Inner diameter of the tube from 20mm to 150mm.
• Heated Length from 100mm to 1000mm.
• Furnace design with powerful heating elements i.e. FeCrAl, SiC and MoSi2 in all sides of the work tube providing fast heating rate.
• Vacuum provide by turbo molecular pump/Rotary vane pump with pirani/penning gauges and related fittings.
• Work tube connects with the vacuum system via stainless steel below pipe.
• Access to the work tube can be removable via stainless steel vacuum flanges.
• Radiation shields at both end of the work tube to maintain uniformity without reducing pump speed.
• Fast heat up and cool down rates.
• Temperature uniformity +/- 5°C.
• Temperature control with PID controllers.
• Power control with solid state relays or Thyristor units for very precise temperature Control, wear-free and noiseless.
• High mechanical durability, short heating cycle and low power consumption.

Vacuum Tube Furnaces are designed for R&D labs, Educational institutions, Medicine and Industry, Chemical Industries, Biomedical Industry, Pharma Industry, Thermal Process Technology, Advanced Materials for following applications:
