Carbolite GVA GVC Vertical Tube Furnaces all supplied without work tube, maximum temperature 1200C. Continuous temperature 1100C.
Carbolite Gero GVA is single zone bench mounted furnace and the GVC 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 furnace is supplied with stand for vertical use, this can be wall mounted or even used in a horizontal position. The controller is separated from the furnace by 2 metre conduit. Standard controller supplied 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.
