Vacuum heating tubes are heating elements designed using vacuum technology, primarily used for heating requirements in high-temperature and high-vacuum environments. They feature high-temperature resistance, uniform heating, and a contamination-free surface.
Core Structure
Composed of a stainless steel heating tube, vacuum interlayer, and insulation layer, with an outer diameter range from 3.0mm to 30mm, supporting voltages from 55V to 380V. Made from USU304, 310S stainless steel, or GH3030 alloy materials to ensure stability under high temperatures.
Technical Features
High-Temperature Stability: Maximum operating temperature up to 900°C, suitable for high-temperature processes such as vacuum coating and solar photovoltaics.
Uniform Heating: Flexible design allows dense arrangement within the vacuum chamber, avoiding heating dead zones, with temperature uniformity superior to traditional heating elements.
Long Lifespan: Special materials and processes ensure a service life of over three years.
Application Areas
Industrial Processing: High-temperature heating scenarios in vacuum coating equipment and solar photovoltaic equipment.
New Energy: High-temperature treatment processes in the production of solar thermal collector tubes.
