Laboratory & pilot vacuum dryers
Our laboratory & pilot vacuum dryers are small vacuum drying systems that have been specially developed for use in laboratories. They are multi-purpose systems for wide-ranging applications.
The complete systems, including all of the necessary ancillaries, are built on stainless steel skids with wheels. They are very suitable for process development activities, experimental purposes and for fine-tuning for optimal process parameters. The laboratory dryers are available from 5 litres to 20 litres and the pilot dryers from 40 to 120 litres.
Standard industrial dryers
Our industrial dryers are available in sizes of up to 22 m³. They are designed and built according to industry standards such as Stoomwezen, PED, TÜV, Lloyd’s, ASME, Afnor, ISPLE etc. and are available in all grades of stainless steel, Monel, nickel, titanium, Hastelloy, etc.
