1700°C & 1800°C HORIZONTAL TUBE FURNACES

General Features

Maximum operating temperatures of 1700°C and 1800°C.

Use with process tubes up to 3.5" OD.

Available in heated lengths of 12" and 24" single zone.

The 24" heated length is also available in a 3 zone design.

Three zone tube furnaces provide a longer uniform temperature zone through elevation of end zone temperatures to compensate for normal end losses.

All Carbolite 1700°C and 1800°C tube furnaces are fitted with a 3216P1 programmable temperature control and a separate independent over-temperature protection control.

Long-life free radiating molybdenum disilicide heating elements provide excellent radial and linear uniformity.

Advanced high temperature graded insulation assembly provides improved energy efficiency and heat-up rates.

Furnace controls are built into the furnace cabinetry, providing convenient observation and access to all power and temperature controls.

Low outer case temperature provided through double shell construction.

Mesh tube guards at ends of furnace prevent accidental contact with hot tube.

Insulating end vestibules improve chamber uniformity.

Molybdenum disilicide element resistance does not change with usage, providing no restriction on placement of a new element in circuit with older elements.

Three zone furnaces incorporate three separate temperature controls to allow variation of set point temperature in each zone.

Serviceability is aided by furnace mechanical and electrical design.
