Tempering Ovens

The tempering ovens series VAW represent 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 & defence industries, Vötsch Industrietechnik offers the appropriate ovens which fulfil the requirements of the standard AMS 2750 D.
