Using the latest photocatalytically enhanced UV technology the Pro Pond TitanUV is up to 1.5 times more effective than a standard UV clarifier, producing hydroxyl radicals that improve water clarity through a process of oxidation. The special interior lining of these UV-C units acts as a catalyst to convert UV-C light into hydroxyl radicals. Operational pressure 3 bar. Standard 63mm and 2 inch solvent connection. The Pro Pond UV110 can only use the spare UV bulbs SB717 & SB719. - Clears green water fast! - UV effectiveness is enhanced 1.5 times - Resultant hydroxyl radicals work like ozone to clear the water even further - The reaction is instantaneous, completely contained with no harmful by-products leaving the unit - Prolonged life of the plastic body due to UV shielding - Perfectly safe for all pond life - Ideal for use in natural swimming ponds/biopools!
