Circulating air ovens UT

Drying, heating, tempering and sterilizing

Certain products are not suitable for drying under vacuum or do not require this technology. For these PINK offers a comprehensive range of circulating air ovens in a huge variety of versions. These ovens can be used for drying under atmospheric conditions and for heating, tempering and sterilizing.

For drying products containing solvents under normal pressure, PINK again has a highly reliable solution. The UT-ex circulating air oven with external solvent recovery offers such features as a safe condensation and collection of potentially explosive solvents for proper disposal at any time.
