The design of these new UVs optimises flow rates and improves energy efficiency with the sole focus to deliver optimum performance at all times to clear green water in ponds which is caused by single celled green algae. evoUVs will work alongside many different filtration systems and are incredibly easy to install with flexible hose or hard pipe and can be easily fitted within existing pipework runs. All evoUV models come with high output UV bulbs powered by energy efficient ballasts all housed within a fully watertight robust housing.
