PC Series™
Vacuum Oven

It’s critical.
When uniform temperature and precise process gas environment are critical, the T-M Vacuum PC Series™ Vacuum Oven fits the bill.

The PC 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 a precise heating environment while allowing you full use of the interior of the oven.

Both the PC-26 and PC-36 models are fitted with a 23.3 cfm dual-stage direct drive mechanical vacuum pumping system and the PC-48 includes a 42.4 cfm pump.

Available in various high-vacuum configurations to fit your needs, PC 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 PC 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 PC Series vacuum oven incorporates varying degrees of automation ranging from our standard PLC control to full HMI computer control with data logging and recipe management.
