Multi Arch Tungsten Heater
What's Multi Arch Tungsten Heater?
Multi arch tungsten heater, alternatively known as multi peak tungsten heater, is a high-temperature resistance heating element manufactured from high-purity tungsten wire or stranded tungsten wire through multi-stage precision bending processes. It is primarily utilized for heavy-duty evaporation heating processes within vacuum evaporation coating and high-temperature thermal field systems.
Characteristics of CTIA’s Multi Arch Tungsten Heater
(1) Highly efficient heating: Overlapping multi-peak designs expand effective heating surface area and thermal capacity, ensuring more uniform heating of deposition materials for large-area continuous coating and high-load operating conditions.
(2) High-temperature stability: With a melting point of approximately 3,422°C, tungsten provides exceptional creep resistance and structural integrity at temperatures exceeding 2,000°C.
(3) Low contamination: Low vapor pressure minimize the impact of high-temperature volatilization on vacuum environments and film purity.
(4) Reliable materials: Utilizing high-purity tungsten wire with a purity ≥ 99.95%, with optional potassium-doped tungsten wire to enhance high-temperature non-sag performance.
(5) Broad environmental compatibility: Capable of reliable long-term operation within vacuum environments or inert gases such as argon and nitrogen, covering a temperature range of 1,800°C to 2,600°C.
(6) Adjustable configurations: Power levels and evaporation profiles are precisely matched through the adjustment of peak counts, peak heights, and peak spacing.
