: A Quartz Sleeve is a transparent tube made from high-purity quartz glass that encases the UV lamp inside a sterilization chamber. Its primary purpose is to protect the lamp from direct contact with water or other liquids while allowing maximum UV light transmission.
Because quartz glass has exceptional UV transmittance, the Quartz Sleeve ensures that over 90% of the UV radiation reaches the water, making the disinfection process highly effective. It also acts as a barrier against scaling, corrosion, and contamination that could damage the lamp.
Regular cleaning and maintenance of the Quartz Sleeve are essential to maintain system efficiency. Over time, mineral deposits or biofilm buildup can reduce UV output, so periodic inspection and gentle cleaning help sustain peak performance.

UV Ballast Water Treatment Spare Parts are replacement components used in ultraviolet (UV) ballast water management systems installed on ships. These systems disinfect ballast water by using UV light to eliminate invasive aquatic organisms, ensuring compliance with IMO and USCG regulations. Spare parts—such as UV lamps, quartz sleeves, wipers, sensors, and power supplies—are crucial for maintaining system efficiency and minimizing downtime. Regular replacement of these parts helps vessels achieve optimal performance, reduce maintenance costs, and stay compliant with international maritime standards.

The replacement schedule depends on the specific part and the system’s usage. UV lamps typically need replacement every 9,000–12,000 hours of operation. Quartz sleeves may need replacement every 2–3 years, while O-rings and seals should be checked regularly and replaced if damaged. Following the manufacturer’s maintenance guide helps maximize efficiency and system life.
