- Model HTRV - High Temperature Vertical Tube Furnaces

From

0

The HTRV high temperature tube furnaces are designed for vertical orientation and operation up to 1800 °C. The high grade insulation material consisting of fibre plates provides low energy consumption and high heating rates due to its 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.

With its wide range of accessories, the comprehensive HTRV tube furnace range provides complete system solutions for ambitious thermal treatment at high temperatures.

Furnaces are supplied without a stand, allowing customers to build them into their own equipment. Optional ‘L’ stands are available allowing the furnaces to be self supporting.

Annealing, carbonisation, crystal growth, debinding, degassing, drying, hardening, metal injection moulding (MIM), pyrolyses, rapid prototyping, sintering, sublimation, synthesis, tempering
