Yamitsu Quartz Sleeves

Yamitsu Quartz Sleeves

High-clarity fused quartz protective sleeves designed to maximise UV-C performance, protect UV lamps, and maintain optimal pond water sterilisation efficiency

The Yamitsu Quartz Sleeves are precision-engineered protective components designed for use in Yamitsu pond UV steriliser systems. Their primary function is to insulate the UV lamp from direct water contact while ensuring maximum transmission of ultraviolet-C light for effective algae control and water clarification.

By separating the lamp from the water, the quartz sleeve allows the UV-C bulb to operate under stable conditions, preventing performance loss caused by moisture, debris, or mineral deposits. This ensures consistent sterilisation efficiency and helps maintain long-term reliability of the UV system.

Manufactured from high-purity fused quartz, these sleeves offer exceptional optical clarity across a wide UV spectrum, allowing UV-C light to pass through with minimal reduction in intensity. The material is also highly resistant to thermal shock, scratching, and solarisation, making it suitable for continuous use in demanding pond environments.

Proper maintenance of quartz sleeves is essential, as even minor build-up of algae, limescale, or debris can reduce UV transmission and impact overall pond clarity. Regular inspection and cleaning help ensure optimal system performance.

Benefits

• Maximises UV-C light transmission efficiency
• Protects UV lamp from direct water contact
• Prevents performance loss from mineral or algae build-up
• High resistance to thermal shock and scratching
• Maintains consistent pond water clarity
• Extends lifespan and reliability of UV system

When to Use

• Replace or clean when sleeve becomes cloudy or stained
• During annual UV system maintenance
• When UV performance or water clarity declines
• After prolonged use in hard or mineral-rich water
• When servicing or replacing UV lamps

How It Works

• Forms a protective barrier between UV lamp and water
• Allows UV-C radiation to pass through clear quartz walls
• Prevents contamination from water, algae, and limescale
• Maintains stable operating conditions for UV lamp
• Ensures consistent sterilisation efficiency over time

How To Use

• Switch off and disconnect UV system before servicing
• Carefully remove quartz sleeve from housing
• Clean with suitable non-abrasive materials if reusing
• Replace if cracked, clouded, or damaged
• Install securely into UV unit ensuring proper sealing
• Reassemble system and check for leaks
