Vacuum Shelf Ovens

Principally, Drying under vacuum is environmentally friendly because the Evaporated Solvents can easily be re-condensed. These solvents can then either be recycled or disposed of without any problem.

Drying of solvents in Ex-proof ovens may solve the safety problem in the oven but not the environmental aspect. The solvent vapour is blown out of the oven through the exhaust system Furthermore, there is a risk of uncontrolled mixture formation. 

• A major design feature incorporated in this series of vacuum dryers is the placement of all shelf and manifold connection outside of the chamber, avoiding the possibility that leaks might develop within a chamber and contaminate the product being dried. This feature also simplifies the maintenance of these connection by making access to them more convenient.

• Charge temperature measuring facility provides exact picture of the process. It measures the temperature directly at charge (material). A PT-100 Temp. Sensor enters the vacuum chamber via connection at the top Rear.

• "SANDWICH" Type High Thermal efficiency Stainless Steel Shelves with the heat transfer fluid circulation. Even heat distribution through whole shelf surface by baffles within shelves.

• Chamber walls are heated externally to prevent condensation on the internal walls.

• Rounded edges in walls shelves and product trays in order to facilitate cleaning and prevent accumulation of dry product residue and practical formation.
