Vacuum circulating air ovens VUT

Reliable drying with a combination of vacuum and circulating air

To vacuum-dry a product that is embedded in a product carrier or, due to its inherent structure, exhibits poor heat transfer by conduction, it makes good sense to combine two different forms of drying: vacuum and circulating air.

For such applications, PINK has its VUT vacuum circulating air oven. The product is heated to a defined temperature by circulating air, then a vacuum is generated. This process runs alternately, the number of cycles depends on the product's drying behaviour.
