Modular Horizontal Tube Furnace GHA / GHC
The extended uniform zone in the mid-section of the work tube in the GHC 3-zone furnace is achieved with the use of end zone controllers which track the centre zone temperature and compensate for the loss of heat from the tube ends.
This range of tube furnaces does not include an integral work tube and one must be selected as an additional item. The work tube length is dependent on the application, for example, for use with modified atmosphere or vacuum. The use of a separate work tube has the advantage of protecting the heating elements from damage or contamination.
Standard features
- 1200°C maximum operating temperature
- Carbolite Gero 301 controller, with single ramp to set-point & process timer
- Accepts work tubes with outer diameter up to 170 mm
- Heated lengths, single zone 300, 450, 600, 750, 900, 1050 or 1200 mm (GHA)
- Heated lengths, 3-zone 450, 600, 750, 900, 1050 or 1200 mm (GHC)
- End zones 150 mm long on each end (GHC)
- Long life, rapid heating, resistance wire elements mounted in rigid, vacuum formed insulation modules
- Horizontal configuration mounted on control module
- Furnace mounted directly on top of controller base unit
Options (specify these at time of order)
- A range of sophisticated digital controllers, multi-segment programmers and data loggers is available. These can be fitted with RS232, RS485 or Ethernet communications
- Over-temperature protection (recommended to protect valuable contents & for unattended operation)
- A range of additional work tubes, end seals and work tube packages is available for use with modified atmosphere and/or vacuum
- Vacuum packages with a choice of rotary vane pump or turbomolecular pump are available for furnaces with tube inner diameters of 60 mm and above
- Wide choice of tube diameters and materials is available: eg quartz, ceramic, metal
- Insulation plugs & radiation shields to prevent heat loss & improve uniformity
- End zones 300 mm long (GHC)
- Modified atmosphere and vacuum assemblies are available
- Over-temperature protection (recommended to protect valuable contents & for unattended operation)
- Retransmission of setpoint control configuration to facilitate programmed cooling
- Alternative mounting options are available
