Scholz Hot Air Autoclave
SCHOLZ Hot Air Autoclave – modernized in 2019 – Working autoclave with quick-release closure
Description:
For sale is a SCHOLZ hot air autoclave that underwent extensive modernization between 2019 and 2024. The system is designed for the thermal treatment of materials under overpressure conditions and offers reliable and precise process control thanks to modern control technology and proven SCHOLZ construction.

Modernizations carried out:
In 2019:
- Installation of a new STANGE 604 program controller including control software and data logging
- Integration of a new Siemens SIMATIC S7-1500 controller (TIA Portal)
- New thermocouple feedthroughs for 12 component temperature sensors, type K
- Installation of new thermocouple panels for connecting thermocouples inside the autoclave
- New thermocouple feedthroughs for 12 additional sensors for TUS measurement, including terminal panels inside and outside the autoclave

In 2023:
- Replacement of several control valves for compressed air and cooling water control

In 2024:
- Installation of a new rotary vane vacuum pump

Modernized, well-maintained condition
Status: Final version, revision dated 11.09.2019
