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
