Heating in a Vacuum

Heating a vacuum isn't possible. There is nothing to heat. When referring to "heating a vacuum," we mean heating an object located inside a vacuum. Regardless of the heater type, all vacuum heating is accomplished with radiant heating. Some heater types physically lend themselves more readily to an application than others. The application descriptions below will give you a general idea on how a particular heater type is applied for heating an object inside a vacuum.


Cable Heaters

Coiled or sinuated, and mounted in a vacuum vessel for radiant heating.


Cartridge Heaters

Mounted in a vacuum vessel for radiant heating.


Ceramic Fiber Heaters

Constructed to surround and heat the vacuum vessel so it re-radiates heat to the load.


Flexible Heaters

Applied to the exterior or interior surface of a vacuum pipe or vessel. Well suited for curved and irregular shaped objects. Note: Polyimide is the only flexible heater material recommended for use in the vacuum.


Multicell Heaters

Mounted in a vacuum vessel for radiant heating.


Radiant Heaters

Mounted in a vacuum vessel for radiant heating.


Strip Heaters

Mounted in a vacuum vessel for radiant heating.


Tubular Heaters

Mounted in a vacuum vessel for radiant heating.
