Applications of vacuum drying
Industries and application areas
Our vacuum drying cabinets and vacuum drying chambers are used in chemicals, pharmaceuticals, research and development, electronics manufacturing, process engineering, environmental protection, metalworking as well as vehicle construction and aerospace. Choose the product for your task.
Drying
Gently drying powders and granules in a vacuum drying cabinet
Under vacuum, the temperature at which moisture evaporates drops. Powders and granules can thus be dried at moderate temperatures and in less time than in a conventional drying oven.
This protects temperature-sensitive products, dehumidifies reliably and shortens the drying process efficiently. Reactive materials can also be dried quickly at low temperatures.
Suitable devices
Vacuum drying cabinets and vacuum drying chambers of the VETK series, depending on the batch, from the built-in unit EWA VETK 27 up to the large chamber EWA VETK 2000. With shelves, stainless steel interior or TEFLON®-coated, GMP-compliant on request.
Typical industries
Chemistry, pharmaceuticals, electronics manufacturing, research and development
Sludge and oils
Recycling and degassing sludge and oils
Vacuum systems can be used to dry sludge and make it reusable, and to degas oils.
There is a dedicated, specialized solution for oil-contaminated metal chips and grinding sludge from machining: De-oiling chips and recycling metals.
Suitable devices
Vacuum drying cabinets, vacuum drying chambers and vacuum systems, designed for your process, with heating via jacket or shelves. You will find all devices in the Product overview.
Typical industries
Process engineering, environmental protection, industry
Chips and metals
De-oiling chips and recycling precious and non-ferrous metals
Machining precious and non-ferrous metals with non-water-miscible cooling lubricants or oils produces oil-contaminated chips. With a vacuum system from ELEKTRO-WÄRME-AACHEN, you de-oil these chips directly in production, without losing time. The valuable material does not have to leave the premises, internal material flows are optimized and capital tie-up is reduced.
The principle: Under vacuum, the temperature at which the oil evaporates drops. In addition, oxygen is absent, so the material does not oxidize. The oil is recovered in the condenser and collected in a receiver.
Feedstock:
- Chips from turning, milling, planing and similar processes
- Grinding sludge
- Stamping waste with cooling lubricant
Suitable devices
The vacuum drying cabinet EWA VRTK 130 with a round interior, integrated vacuum pump stand, condenser and collecting container is designed for this task. We solve larger or different tasks as custom-made units.
Typical industries
Metal processing and machining (turning, milling, grinding, punching), recycling and precious metals
Extraction and samples
Material separation, solvent extraction, degassing and sample storage under vacuum
Under vacuum, material fractions can be separated by evaporation and condensation, foreign gases absorbed, and samples stored under adjustable vacuum and temperature conditions.
Flammable solvents can be extracted in explosion-proof systems, including recycling if required. We configure the right system for laboratory and production.
Suitable devices
Vacuum drying cabinets and vacuum drying chambers of the VETK and VRTK series, configured for laboratory and production. For flammable solvents there is the explosion-proof vacuum drying chamber EWA VETK 1500 Ex. You will find all devices in the Product overview.
Typical industries
