The Vacu Bake ™
Vacuum/Inert Gas Ovens

They are versatile, yet still economical.

The TM Vacuum Vacu-Bake vacuum ovens series offer high quality and versatile vacuum ovens at economical prices.

With temperature capabilities ranging from ambient to 600°C, and capable of incorporating any degree of vacuum environment from atmosphere to 10-8 torr, the Vacu-Bake vacuum ovens offer a wealth of possibilities.

The Vacu-Bake vacuum ovens include a chamber with 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, hightemperature insulation with reflective shield surrounding its heater bank, the vacuum ovens maintain a stable processing temperature inside the chamber at all times. The Vacu-Bake series vacuum ovens offer standard electro-pneumatic inert gas fill and vent valves allowing for various types of part processing using a gas back-filled environment.

The T-M Vacuum Vacu-Bake vacuum ovens series come standard with automated control packages so you can simply load the ovens and press the start button! With many options available such as gas stirring fans, quick cool, alternate pumping packages and HMI control systems, the Vacu-Bake makes it simple for you to control your process and its cost!
