Three-zone split tube furnace HZS 12/-/900E/E30 Carbolite Gero

Pyrolysis is the thermochemical decomposition of organic compounds under high temperatures (400-900 °C), high pressures and anaerobic exclusion. Products include pyrolysis gas, pyrolysis oil and pyrolysis charcoal.

The HZS series horizontal folding ovens are divided into three control zones with their own thermocouples and controllers.
The free-standing resistive wire heating elements, which are embedded in vacuum-formed fibre ceramic, ensure rapid heating rates, short cooling times and very good temperature homogeneity.

A device from Carbolite Gero, model HZS 12/-/900E/E30, is used.
