Genuine High-Performance Spare Parts

A UV steriliser is a long-term investment in the health of your system. To ensure it consistently delivers peak performance, regular maintenance with high-quality, genuine spare parts is essential. Inferior or mismatched parts can lead to drastically reduced UV output, premature failure, and ultimately, a compromise in water quality.

  • High-Transmissivity Quartz Sleeves: Protect your lamp and ensure maximum UV-C penetration with our pure fused-quartz sleeves, essential for optimal germicidal effectiveness.
  • Matched Electronic Ballasts: Power your lamp correctly with reliable electronic ballasts designed to provide stable current, maximising both lamp life and UV output.
