Carbolite GHA GHC Horizontal Tube Furnaces all supplied without work tube, maximum temperature 1200C. Continuous temperature 1100C.

Carbolite Gero GHA is single zone bench mounted furnace and the GHC is the three zone version. Both types of furnace can accommodate a large overall diameter of work tube up to 170mm. Adaptors allows 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 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, this and the use of a separate work tube reduces the probability of element damage. Insulation is vacuum formed provided fast energy efficient heating.
