All of our evoUVs have been designed using the very latest design techniques to ensure that the water will flow effectively within the unit, allowing the ultraviolet light to destroy the algae as it passes through. Not only does the evoUV look very stylish, making it a fantastic addition to any pond, but it has been designed with a fully UV stabilized, tough outer casing. This means that the evoUV can withstand the recommended operating pressures. The evoUV has a low energy, electronic ballast that is positioned in a fully water tight compartment, fused, with full thermal overload protection. Your evoUV is built with both safety and low running costs in mind.
