The new [e]pool speed drive is valid for all public pool pumps on the market, from 0.5HP to 5.5HP. The system allows the programming of several daily fltration cycles with different operating speeds for each cycle. In installations with several pumps, the inverter will communicate and alternate with other inverters so that the pumps work the same number of hours. In addition, it is capable of operating several pumps at the same time. Thanks to a simple assistant, the necessary information is provided to the pump to have a fully operational installation. With the help of a pressure transducer and a small electrical panel (supplied separately), it is capable of automatically cleaning the sand filters, if they have motorized valves.
