Tempering Ovens

The tempering ovens series VAW represents a construction concept which has been proved, tested and enhanced over decades and therefore is suitable for many heat treatment processes on different materials.

The nominal temperatures are 500 °C, 650 °C or 750 °C depending on the model in question. The ovens consist of a double-walled, self-supporting steel plate construction with an insulation material of high-quality mineral fibres. The working chamber is made of heat-resistant material and is welded tight. The oven air is heated using an electrical resistance heater and recirculated by means of a powerful radial fan. The circulated air is routed horizontally through the working chamber.

• The ovens are suitable for almost all heat treatment processes, e.g tempering and hardening of steel
• Ageing and stress-relieving of metals
• Solution annealing of light metals

Preheating of metals for the following manufacturing processes:

• Sintering of plastic materials based on polytetrafluoroethylene basis (PTFE)
• Burning-in of special coating materials after drying
• Burning-off of organic residues on metal parts

Advantages:

The advantages of the VAW series are high functionality, reliability and durability.

The ovens are supplied ready for installation thus avoiding long commissioning times.

Further advantages include:

Cost-effective

• High air rate: The material soon reaches the required temperature
• Short heating and cooling rates thanks to insulation material with low thermal capacity
• Reduced external wall temperatures thanks to high-quality insulation system

Flexible

• Extensive range of accessories and equipment enable universal use

Ergonomic

• Low noise emissions
• Operating and maintenance-friendly concept

Safe

• High operational safety thanks to swing mechanism of the test space door: Hot side facing away from the operator
• Adjustable safety cut-out against excess temperature with selection limiter (Protection Class 2)

Control system

All equipment necessary for regulating and controlling are in the switch cabinet. The controller used is a microprocessor- controlled PID controller with digital display. The semi-conductor relay is silent running without mechanical wear.

For heat treatment of material used by the aerospace and defence industries, Vötsch Industrietechnik offers the appropriate ovens which fulfil the requirements of the standard AMS 2750 D.
