VACUUM TUBE FURNACE

A tube furnace comprised of round heating chamber, Quartz or Alumina tube, vacuum pump and related fittings. Depending upon application, a tube furnace can be designed in different configurations, temperature ranges and optional accessories. Most commonly these laboratory tube furnaces are classified as Horizontal Tube Furnace, Vertical Tube Furnace, Multi-angle, Solid, Split and Rotary types. Furthermore, tube furnaces are also designed in single zone, two zones, three zones and multi zones up to five zones as required. Typical applications of a tube furnace are chemical analysis, physical decomposition, purification, sintering, sublimation, degassing and tempering etc. SIGMA is one of the top tube furnace manufacturers in India. We make tube furnaces for laboratory research and industrial applications. We also offer customization and modification of tube furnace to meet specific requirement at competitive price in India. We offer supply, installation and service throughout India and overseas.

Our tube furnaces comprise of a furnace body with alumina ceramic fiber heating chamber, heavy duty outer shell and hinges. As standard, quartz tube is supplied for 1200°C tube furnace and alumina tube is supplied with 1400°C and 1800°C tube furnace. Complete furnace is supplied with heating tube, Vacuum pump and vacuum fittings. Standard tube heating zones are available in 200mm, 300 mm, 350 and 450 mm etc. with outer diameter 40mm, 60mm, 80mm and 100mm.

These vacuum tube furnaces are made in 1200°C, 1400°C and 1800°C maximum temperature ranges supported with programmable temperature controller. These units are designed for laboratory research, industrial research and education purposes including IIT, NIT and Engineering collages etc. sigma tube furnace guarantees excellent temperature accuracy, uniformity and ease of use.
