Jaye Heater's Diffusion Pump Heaters are engineered for superior performance in vacuum coating systems, delivering stable high-temperature operation, efficient heat transfer, and long service life. With customizable designs and reliable quality, they ensure consistent vacuum performance for high-precision coating applications across various industries.

Achieves Ultra-High Vacuum Levels
Diffusion pump heaters provide the necessary thermal energy to vaporize pump oil and generate molecular jet streams, which are essential for reaching the ultra-high vacuum conditions required in vacuum coating applications.
Enables High-Quality Coating Results
Stable vacuum levels ensure consistent film deposition, improved adhesion, and uniform thickness-critical for optical coatings, semiconductor layers, and decorative finishes.
Reduces Downtime and Maintenance
With no moving parts and long service life, these heaters contribute to the smooth and continuous operation of the coating process, reducing maintenance frequency and costs.
Supports Wide Range of Coating Materials
Whether you're working with metals, ceramics, or polymer films, diffusion pump heaters provide reliable heating for consistent vacuum performance across various materials.
1. High Thermal Efficiency
Designed to convert electrical energy into heat with minimal loss, ensuring fast startup and consistent temperature control during long coating cycles.
2. Corrosion and Oxidation Resistance
Constructed from durable materials like stainless steel, mica, or ceramic insulation, the heaters resist damage from chemical vapors present during vacuum deposition.
3. Uniform Heating Distribution
The heater delivers evenly distributed heat to the pump fluid, promoting stable vapor flow and minimizing thermal gradients that could affect coating quality.
4. Customized Options Available
Heaters can be customized in terms of voltage, wattage, shape, mounting type, and dimensions to suit different sizes and models of diffusion pumps used in vacuum coating equipment.
5. Safe and Reliable Performance
Built-in over-temperature protection and compatibility with external thermal control systems enhance operational safety during high-temperature processes.
