Ultra Violet Lamp systems
Yamitsu UV systems
Yamitsu UVs are one of the best selling UV systems and have been in production since 1990. They are manufactured from UV stabilised materials and are rugged and reliable. They are fully electronically controlled for reliability and long life - and importantly to ensure low running costs. Did you know that the average UV system using 'conventional' electro mechanical control gear consumes over four times as much electricity as an electronic model? So a conventional 30 watt UV can actually consume as much as 160 watts of power! They are easy to install with all models featuring glued hose tail connections for flexible pipe work, and 1.5" inlet/outlet ports ready to glue to solid pipe work connections too. They also come complete with mounting clamps. All models are easily serviced and control gear can be replaced if required. Still the most cost effective UV systems available. When calculating the size of UV required, start on the basis that 10watts is required for every 1000 gallons.

EVO TI electronic UVs
The all new Evolution Aqua evoUV Ti, Titanium Enhanced UV Clarifiers are made using the latest technology and are lined with a thick and polished titanium tube, to clear green pond water fast. When the UV light strikes the internal surface of the titanium chamber it produces an instant photocatalytic reaction and generates Hydroxyl Radicals, a powerful oxidant, that instantly destroys organic and inorganic matters, neutralising water-born algae, bacteria and viruses resulting in clearer water whilst being perfectly safe for all pond life.All this plus the same great features available as standard on the existing EVO UV range. The new EVO-TI range is available in two sizes, 55 watt and 110 watt,
