Excellent High-Temperature Resistance
Capable of withstanding continuous high operating temperatures without degradation or compromise to performance. This characteristic ensures the sleeve’s durability and integrity even when enclosing high-output UV lamps that generate significant heat.
High Chemical Resistance
Made from high-purity quartz glass, these sleeves are exceptionally resistant to a wide range of corrosive chemicals, acids, and alkalis commonly found in water or air treatment environments. This prevents material degradation and ensures long-term reliability and purity.
Superior UV Transmission
Engineered to allow maximum transmission of ultraviolet (UV) light, especially in the UV-C spectrum. This ensures optimal germicidal efficiency for water purification, air disinfection, and other UV-driven processes, directly impacting the effectiveness of the UV lamp.
Ultra-High Purity & Smooth Finish
The ultra-high purity of the quartz material minimizes the leaching of impurities into the surrounding medium (water/air) and prevents optical degradation. The smooth finish helps prevent the build-up of scale or deposits, maintaining UV transparency over time and reducing maintenance frequency.
Application Scenario
UV Water Purification Systems
These sleeves are a critical component in ultraviolet water treatment systems, where they protect the germicidal UV lamps from direct contact with water. They allow the UV-C light to effectively penetrate and disinfect the water by neutralizing bacteria, viruses, and other pathogens, without the lamp itself being immersed.
Air Disinfection and HVAC Systems
Similar to water treatment, quartz sleeves are used in air purification units and Heating, Ventilation, and Air Conditioning (HVAC) systems. They encase UV-C lamps to sterilize circulating air, preventing the spread of airborne microbes and improving indoor air quality, while protecting the lamp from dust and moisture.
Industrial and Municipal Wastewater Treatment
In large-scale industrial and municipal wastewater treatment facilities, high-power UV systems are employed for advanced disinfection. Quartz sleeves provide essential protection for these powerful UV lamps against abrasive particles, corrosive chemicals, and high-pressure flows inherent in complex wastewater streams, ensuring consistent and effective treatment.
Swimming Pool and Spa UV Sterilizers
For residential and commercial swimming pools and spas, UV sterilizers are used as a chemical-free or reduced-chemical disinfection method. The quartz sleeves are vital for protecting the UV lamps from pool chemicals and water, enabling the UV light to effectively eliminate chlorine-resistant microorganisms and maintain clear, healthy water.
Handle with care
Quartz glass products are made from valuable materials and must be handled gently to avoid collisions and falls.
Regular maintenance
The maintenance of quartz tubes must be performed regularly to ensure their long-term stable performance. Regularly check the connections, fixings, and mechanical vibrations of the quartz tubes to prevent abnormalities. The exterior of the quartz tubes is prone to contamination from dust and moisture, so they should be cleaned regularly.
Storage environmen
When storing quartz tubes, care should be taken to avoid exposure to mechanical vibrations, shocks, and excessively high temperatures. They should be kept in a dry, cool, and well-ventilated place, avoiding direct sunlight and high-temperature environments.
Our quartz glass sleeves are designed to be highly versatile and are available in comprehensive specifications to fit a wide range of UV lamps. We offer various diameters, lengths, and end configurations (single open-end with sealed bottom or double open-end) to ensure compatibility. For specific lamp models or unique system designs, we provide custom manufacturing solutions to guarantee a perfect fit.
Our quartz sleeves are manufactured from ultra-high purity fused silica, which offers superior UV transmission, particularly in the critical UV-C spectrum. This high transparency ensures that the maximum amount of germicidal UV light passes through the sleeve to effectively disinfect water or air. The smooth finish also minimizes light absorption and scattering, maintaining optimal disinfection efficiency over time.
The lifespan of our quartz sleeves is significantly extended due to their excellent high-temperature resistance and high chemical resistance, making them highly durable. While the sleeve itself is long-lasting, regular maintenance, such as periodic cleaning to remove any mineral deposits or biofouling, is recommended to maintain optimal UV transmission. This simple maintenance helps ensure the continuous effectiveness of your UV disinfection system.
