INTERCHANGEABLE HOT ZONES

Each Pressmaster furnace will accept four different hot zones which are easily interchanged. All internal components (including heating element, insulation, and power feedthroughs) are mounted on the front and rear vacuum chamber doors. To change zones, simply disconnect the power leads, remove the doors from their hinges, and replace with alternate door/hot zone assemblies. Both doors and the main chamber are fabricated from double-walled carbon steel with internal baffling for efficient water cooling. Stainless steel doors and chambers are available for areas with poor water quality which could accelerate corrosion or when the ultimate high vacuum performance is required.
