UV Quartz Sleeves

High-Purity Fused Silica Protection for Advanced UV Sterilization Systems.

Our uv quartz sleeve products, also widely known in the industry as uv quartz tube components, are the premier choice for high-efficiency germicidal applications. Manufactured from semiconductor-grade fused silica (SiO2 > 99.99%), these sleeves protect UV lamps from cooling and mechanical impact while ensuring the highest possible radiation transmission. Every uvc quartz sleeve we produce is optimized for the 254nm germicidal peak, providing an essential barrier for water treatment and air purification systems.

Specialized Material Selection: Ozone Control

For high-end sterilization equipment manufacturers, selecting the correct material is critical to managing ozone production within the system:

1. Ozone Free Quartz Tube (254nm)

For applications where ozone byproduct is undesirable—such as residential air purifiers or standard drinking water systems—we provide the ozone free quartz tube. This material is specifically doped to block vacuum-UV radiation below 200nm while maintaining over 90% transparency for the 254nm germicidal wavelength. Using an ozone free quartz tube ensures safe, effective sterilization without the need for additional ventilation or ozone destruction systems.

2. Ozone-Generating Quartz (185nm)

Conversely, for advanced oxidation processes (AOP) in industrial wastewater, our high-purity uv quartz tube options can be engineered for 185nm transmission. These sleeves facilitate the intentional production of ozone for breaking down complex organic contaminants and odor control.

Engineering Performance of the UVC Quartz Sleeve

The disinfection efficiency of a UV reactor is directly limited by the optical clarity of the protective envelope. A high-quality uvc quartz sleeve must fulfill three core requirements:

High Ultraviolet Transmittance & Solarization Resistance

Long-term exposure to high-intensity radiation can cause standard glass to become “solarized” or brown, leading to a rapid drop in performance. Every uvc quartz sleeve we manufacture is treated to resist this degradation. Our material ensures that the maximum germicidal dose reaches the target pathogens in the water or air stream over thousands of operating hours.

Dimensional Precision for Leak-Proof Sealing

In pressurized water treatment chambers, a uv quartz tube must maintain strict tolerances on outer diameter (OD) and wall thickness. We utilize ultrasonic sensors to monitor concentricity, ensuring that each uvc quartz sleeve fits perfectly with standard industrial O-rings. This precision prevents hydraulic leaks and protects the lamp assembly from moisture damage.ed to resist this degradation, ensuring stable disinfection performance and consistent radiation doses over thousands of industrial operating hours.


Manufacturing Excellence & Quality Control

As a direct factory manufacturer, we maintain a multi-stage quality protocol for every uv quartz tube:

Vacuum Integrity: Our domed-end sleeves are fire-sealed to ensure a vacuum-tight environment, shielding the UV lamp from cooling effects and external contaminants.

Thermal Stress Relieving: All sleeves undergo a precision annealing cycle to eliminate internal tension, preventing structural failure during rapid lamp startups.

Surface Purity: Every uvc quartz sleeve is processed in a 10,000-class cleanroom and undergoes an intensive deionized water rinse to remove metallic particulates that could cause “hot spots” or devitrification.

Custom Fabrication & Dimensional Precision

We support a wide range of secondary processing for UV quartz sleeve or UV quartz tube configurations:

  • Domed / Closed-End Sleeves: For single-ended immersion systems and vertical reactors.
  • Open-Ended Sleeves: Precision-cut with fire-polished edges to ensure mechanical durability during installation.
  • Custom Flanges & Notches: Welding of quartz flanges for secure mounting in high-pressure ballast water treatment systems.
  • Large Bore Sizes: Custom diameters available from 10mm up to 200mm for municipal-scale water plants.

Core Industry Applications

Our high-performance UV quartz sleeve components are the backbone of several critical sectors:

  • Municipal Water Treatment: Protecting high-power lamps in drinking water and wastewater disinfection facilities.
  • Ballast Water Management: High-durability uv quartz tube options resistant to marine salt-water corrosion.
  • HVAC Air Sterilization: Specialized uvc quartz sleeve units designed for medical and laboratory air handling.
  • Food & Beverage Processing: Non-contact surface sterilization and process water treatment.

Maintenance & Handling Guidelines

To prevent premature devitrification and maintain the efficiency of your UV quartz sleeve:

  1. Handling Protocol: Never touch the sleeve with bare hands. Finger oils contain alkali metals that act as fluxing agents, leading to permanent browning or crystallization when exposed to high UV-C intensity and heat.
  2. Chemical Scaling Removal: In water applications, mineral deposits can block UV light. A periodic 5% Hydrofluoric acid (HF) dip or a mild citric acid wipe is recommended to restore the sleeve’s original 90% transmittance.
  3. Material Reference: For detailed technical data on the raw fused silica used in our fabrication, please refer to our Clear Quartz Tubes section.
  4. Storage: Ensure sleeves are stored vertically in a vibration-free, dust-free environment to maintain surface integrity.
