Rectangular Chamber Vacuum Oven

About me


When uniform temperature and precise process gas environment are critical, the Global Vacuum GC series, Vacuum Oven fits the bill.

The GC Series vacuum oven maintains accurate temperature control up to 350 °C (662° F) with its HTP model. The unique, “Hot Wall” chamber configuration is heated uniformly on all sides with a resistive heater bank assembly to create an exact heating environment while allowing full use of the interior of the oven.

Both the GC-26 and GC-36 models are fitted with 23.3 cfm dual stage direct drive mechanical vacuum pumping system and the GC48 includes a 42.4cfm pump.

Available in various high-vacuum configurations to fit your needs, GC series ovens are capable of any degree of vacuum from atmosphere to 10 -8 torr.

Standard cycle times can be greatly reduced by utilizing the GC Series Vacuum Oven’s efficient circulating process gas cycle. The programmable control system option with stirring fan is a cost efficient solution for busy processing environments.

The GC Series vacuum oven incorporates varying degrees of automation ranging from our standard PLC control with data logging and graphic HMI to full computer control.
