The Carbolite GP330B oven allows up to 60 metres of cable to be processed at a time in order to cure the insulation and make it more supple and durable. The procedure typically involves heating the oven at a pre-set rate, holding at temperature for several hours and then cooling to ambient. 

The controller fitted allows up to 20 segments to be pre-set as ramp, step or dwell and also enables operators to store the most frequently used programs.
