Global Vacuum products offers high quality, compact, yet versatile vacuum ovens at economical prices. With temperature capabilities ranging from ambient to 600°C, and incorporating any degree of vacuum environment from atmosphere to 10 -8 mbar, the Vacuum ovens offer wealth of possibilities.

The Vacuum ovens have a chamber that is a “Hot Wall” design, which allows full utilization of the inside of the vacuum chamber, maximizing the load capacity. With up to a 4 ̎ thick, high temperature insulation with reflective shield surrounding its heater bank, the vacuum ovens maintain a stable processing temperature inside the chamber at all times. This series of vacuum ovens offer standard inert gas fill and vent valves allowing for various types of part processing using a gas back-fill environment. With the standard touch screen PLC the operation of the system is fully automated with data logging of the process parameters. Vacuum ovens incorporate removable back plates to accommodate optional double door modification. This enables easy connection and interface with other processing equipment,such as either end of an inert gas environment (glove box) system for pass through applications.

The Global Vacuum ovens feature several standard models with many options available, making it simple to control your process and its cost. Add the automated control package and create automatic processing cycles which enable an operator to simply load the vacuum ovens, and then push the cycle start button.
