Carbolite GHA and GHC Horizontal Tube Furnaces are all supplied without work tubes and have a maximum temperature of 1200°C. Recommended continuous temperature is 1100°C.

The GHA is a single-zone bench-mounted furnace, and the GHC is the three-zone version. Both types of furnaces can accommodate a large overall diameter of work tube up to 170mm. Adaptors allow the flexibility of accepting tubes lower than the maximum overall diameter into the furnace. The controller forms the base of the furnace and is a PID 301 with a process timer and one ramp. Options allow 8 or 20-segment programming with storage.

The furnace heats using free wire radiating elements inside the furnace body, and using a separate work tube reduces the probability of element damage. Insulation is vacuum formed provides fast energy efficient heating.

The models in this range are detailed below; 12 indicates the maximum temperature the following number denotes the heated length in mm.
