The Vacu Bake ™
Vacuum/Inert Gas Oven

It’s versatile, yet still economical.

The TM Vacuum Vacu-Bake Oven Series offers a high-quality and versatile vacuum oven at an economical price.

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 oven offers a wealth of possibilities.

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

The TM Vacuum Vacu-Bake Oven Series comes standard with an automation control package that includes a touch screen, 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!
