Quartz heat exchangers play a vital role in advanced semiconductor, solar energy, and chemical manufacturing industries. Designed specifically for ultra-clean and high-temperature environments, these devices provide precise and reliable thermal management while ensuring the highest chemical purity.

Why Choose Quartz for Heat Exchangers?

Quartz, also known as fused silica, offers unique advantages making it an excellent material for heat exchangers in demanding applications:

  • Exceptional Thermal Resistance
    Quartz can withstand continuous temperatures exceeding 1000°C without deformation or loss of performance.

  • Superior Chemical Compatibility
    It resists aggressive chemicals such as hydrofluoric acid (HF), hydrochloric acid (HCl), and sulfuric acid (H₂SO₄), preventing corrosion and contamination.

  • Ultra-Pure and Non-Metallic
    Quartz does not leach metals or plasticizers, ensuring no contamination of ultrapure fluids.

  • Optical Transparency
    Quartz transmits UV and infrared light, which is beneficial in specialized photothermal processes.

Typical Applications of Quartz Heat Exchangers

Quartz heat exchangers are widely utilized in industries where process purity and temperature control are critical, including:

  • Semiconductor Wet Processing Equipment

  • Acid and Solvent Heating Systems

  • Solar Cell Wafer Cleaning Lines

  • Piranha and SC1 Chemical Baths

  • Quartz Tank Circulation Systems

In these applications, even trace metal contamination can cause defects, making quartz the material of choice to maintain process integrity.
