Process autoclaves

High temperature and process accuracy, durability, made in Germany. For over 100 years, we have specialised in high-performance autoclaves for the thermal treatment of composite materials. From the aviationaerospace and automotive industries to the glass and building materials industries to wood and rubber processing: we offer individual solutions and autoclaves that are perfectly tailored to your requirements worldwide and in all relevant sectors. Are you looking for a partner for advanced and innovative sterilisation technology? With the acquisition of LUBECA, we were able to expand our expertise in the construction of sterilisation autoclaves for the food industry.

Mechanical engineering with passion since 1919.


Every Maschinenbau Scholz autoclave is manufactured specifically to your requirements - down to the smallest detail. This also applies for services that are not explicitly listed in our scope of delivery. We will be glad to advise you.

Our quality promise

Our mission: to find long-lasting solutions for your personal requirements. We achieve this by means of a strong team of experts, continuous quality by using the most modern production facilities as well as customised designs entirely according to your needs. In addition, all necessary tests can be carried out in your company. This guarantees high-quality, tested product features at the highest safety level.


Our autoclaves are built according to European and international regulations and certified according to worldwide standards. To ensure quality, we have a tried and tested system for the acceptance of all equipment by an independent testing body such as TÜV or Lloyd's.

Our service for you

With us, you get everything from a single provider. Based on your requirements, our specialists will design a construction plan with which we can submit an exact offer and take over the order. A permanent contact person is available to answer your questions and respond to your requests - from advice on your individual autoclave to support after delivery.


In addition to the autoclave, you will receive the corresponding software that can control all the details of the electric control.

Guaranteed temperature homogeneity

In order to supply your customers the best possible product, you must be able to rely on your equipment. Our autoclaves offer you very high temperature and process accuracy - which is precisely why many universities and research institutes also rely on our systems.

Optimised energy requirement

We determine your required energy demand based on solid calculation principles - effectively, economically and precisely.


We provide a fail-safe control system for the automation of the opening and closing process of the autoclave door.

Autoclave – Definition, Function and area of application

What are autoclaves?
Autoclaves are gas-tight, sealable pressure vessels that are used for the thermal treatment of constructions and materials in the overpressure range. As a rule, autoclaves are equipped with quick closing doors that enable the pressure vessels to be opened and closed quickly.

Development of autoclaves
The first versions of autoclaves were developed as early as 1679 by the English polymath Robert Hooke. Today, they have developed into complex designs for a wide range of applications - from small application volumes to large production quantities.

Area of application for autoclaves
Industries that rely on the use of autoclaves include the aviation and glass industries, racing, medical and food technology. In addition, laboratory autoclaves are used for research. Examples of their use are, for example:

  • Steam pressure sterilisation of medical items or food. Due to the enormous heat exposure as well as the high pressure inside the autoclave, the protein of the cells of the individual microorganisms coagulates and kills them.
  • Steam curing of building materials such as sand-lime bricks and aerated concrete
  • Vulcanisation of tyres
  • Lamination of fibre composite materials

Production of fibre-plastic composites such as laminated safety glass. The high pressure makes it possible to press the individual laminate layers together.
