EP DROP 1-2: Electronic Panel for Controlling 1 or 2 Pumps on First Rain Collection Tanks
The EP DROP 1-2 is an electronic panel specifically designed for first rain collection tank installations. It ensures the emptying of the first rain collection tank. Once the meteorological event is over, the rain sensor connected to the panel will start the emptying pump after the programmed time has elapsed.
This panel is compact, economical, and very easy to install and program, making it an ideal replacement for older, already installed panels.
