Carbolite 1200°C 1 & 3 Zone Large Bore Tube Furnaces

Maximum operating temperature of 1200°C.
Designed to accept process tubes up to 6.5 inch OD.
Six different heated lengths of 18, 24, 30, 36, 42 and 48 inch provide for multiple working and uniformity requirements.
Insulating end vestibules improve chamber uniformity and incorporate interchangeable tube adapters.
These tube adapters allow convenient conversion to different diameter process tubes.
Long-life free radiating heating element design provides excellent radial and linear chamber uniformity.
High efficiency low mass vacuum formed ceramic fiber insulation enhances heat-up rates.
Carbolite large bore tube furnaces are available in single and three zone designs.
Three zone tube furnaces provide a longer uniform temperature zone through elevation of end zone temperatures to compensate for normal end losses.
Safety outer mesh guard provides low temperature external surface.
Furnaces are normally mounted horizontally on an attractive support base.
Furnace controls are built into the support base, providing convenient observation and access to all power and temperature controls.
Each tube furnace is available for optional vertical operation.
Vertical design is interconnected to a separate control cabinet with a 6 foot cable.
Each three zone furnace incorporates three separate temperature controls to allow variation of setpoint temperature in each zone.
GHC model end zone controllers may be slaved to the center zone or fully independent.
Choice of 301 or programmable controls.
