A vacuum heater is an electric heating device that operates in a vacuum environment, primarily used in vacuum coating equipment, high-temperature processing, and industrial scenarios requiring high vacuum conditions. Below are its main features and applications:
Operating Characteristics
?Material?: Utilizes stainless steel SUS321, SUS316L, and SUS304 as heating tube materials, ensuring corrosion resistance and high-temperature stability. ?
?Insulation Performance?: Cold-state insulation resistance exceeds 50MΩ, ensuring safe operation. ?
?Power Range?: Single-unit power ranges from 0.5KW to 10KW, with customizable outer diameters (Φ3.0MM—Φ30MM) based on requirements. ?
Technical Advantages
?Uniform Heating?: Flexible design allows tight arrangement within the vacuum chamber, eliminating baking dead zones and achieving high temperature uniformity. ?
?Strong Sealing?: Fully stainless steel structure ensures no contamination during long-term high-temperature operation, with no current passing through the surface to prevent arc discharge. ?
?Long Lifespan?: Employs special materials and processes, combined with a control system, to achieve stable operation for over three years. ?
Application Scenarios
Primarily used in vacuum coating equipment (such as the ZZR series armored devices), and also suitable for industrial drying, material processing, and other scenarios requiring high vacuum environments. ?
