Carbolite Gero HTRV High-Temperature Vertical Tube Furnaces

A single zone tube furnace range with a choice of maximum temperatures; 1600°C, 1700°C and 1800°C.  Models available accommodate 40mm up to 200mm overall diameter work tubes.

The furnace and control box are separated by three metres of cable, complete with plug and socket. No stand is supplied so that a customer can integrate the furnace with their equipment. An L stand option is available for furnace support.

High-grade insulation material consisting of fibre plates provide low energy consumption and high heating rates due to their low thermal conductivity. The insulation and the molybdenum disilicide (MoSi2) heating elements are installed in a rectangular housing. The heating elements hang vertically and can be easily replaced. At higher temperatures and in the presence of oxygen, MoSi2 develops an oxide layer which protects the heating elements against further thermal or chemical corrosion.

Supplied without integral work tube as this is dependent on application.
