Consequently, VACTRON vacuum drying ovens are equipped with external heating elements in their base and wall, to maintain working temperatures at a nominal 40°C.

VACTRON vacuum drying ovens are made of stainless steel. The main body is cylindrical and has only one high integrity weld. The lid is a spun stainless steel dish which is pneumatically counterbalanced and is closed to an 'O' ring seal. This design presents a very low stress to the oven at normal atmospheric pressure. Further, the chamber has only two ports: one connected to the evacuation pump, and the other to allow access of thermocouples to monitor work piece temperature.

The oven that is illustrated on the previous page, is 800mm high and 900mm diameter and can accommodate a single, relatively large work piece, or two baskets containing smaller components, one above the other.

VACTRON vacuum drying ovens can reduce drying times. Less than 10 minutes with a residual work piece temperature of approximately 40°C is achieved, which is ideal for penetrant application.

VACTRON vacuum drying ovens require minimal maintenance. With recommended care, they will provide a long and efficient service enhancing many drying processes, including those used prior to penetrant testing.
