A vacuum heater is an electric heating device that operates in a vacuum environment, primarily used for high-temperature processing and material handling in industrial production. Below are its main features and parameters:
Operating Characteristics
?Operating Voltage?: Supports 55V, 110V, 220V, 380V, selectable based on requirements ?
?Operating Temperature?: Can reach up to 800°C or higher, with some models stably operating up to 1150°C ?
?Outer Diameter Range?: Ranges from Φ3.0MM to Φ30MM, designed according to power ratio ?
Structure and Materials
Utilizes a fully sealed stainless steel design (e.g., SUS321, SUS316L, SUS304 materials), with no current passing through the surface and no electrical connectors, avoiding arc discharge contamination ?
The heater is highly flexible and can be evenly and densely arranged in the vacuum chamber, eliminating baking dead zones ?
Performance Advantages
?Long Lifespan?: Uses special materials and processes, combined with a control system, achieving a service life of over three years ?
?Safety?: No high-temperature contamination, maintaining a clean working environment even under prolonged high temperatures ?
?High Efficiency?: Some models achieve thermal efficiency of over 95%, with a heating rate of ≤30°C/min ?
Typical Applications
Suitable for vacuum coating equipment, industrial drying, high-temperature material processing, and other fields ?.
