Vacuum Ovens & Dryers

Using a Votsch VVT Vacuum Oven has many advantages. These include:

  • Heat-sensitive mediums (e. g. pharmaceutical products) are dried with care
  • Reduced drying times due to lowering of the pressure
  • Due to extremely low remaining oxygen content in the oven there are no oxidation processes
  • Evaporating fluids (e. g. solvents) can be recovered
  • Optimum drying conditions for light, powdery products as there is no turbulence (no convection)
  • No “skin-forming” on the product being dried; therefore constant drying performance
  • Economic - steam or warm water from other processes can be used as a heat medium
  • Flexible heating

  • Pharmaceutical industry
  • Chemical industry
  • Cosmetics industry
  • Food processing industry
  • Electrical and electronic engineering
  • Precision engineering and optics
  • Aerospace industry
  • Research and development
  • Microstructure techniques
  • Nanotechniques
  • Plastics and ceramics
  • Textiles
  • Surface techniques

Design

Our Vacuum Drying Ovens are of compact design. The major components are:

  • Drying oven with shelves
  • Heating and cooling aggregate for the thermal medium
  • Vacuum pump
  • Condenser with storage vessel

Construction features

All components of the drying oven itself are of stainless steel with material class 1.4571 as these may come into contact with the product. The external housing and reinforcements are made of stainless steel with the material class 1.4301.

The interior of the drying oven is designed in compliance with GMP-/FDA regulations. This is important when the product being dried should on no account react to other substances or when product entrainment shall be prevented during loading/unloading.

Heating modes

We offer four heating solutions:

  • Electrical
  • With heating medium
  • Infrared radiation
  • Microwave (HF)

For heat treatment of material used by the aerospace and defence industries, Vötsch Industrietechnik offers the appropriate ovens which fulfil the requirements of the standard AMS 2750 D.
