EP DROP 1-2 Electronic Control Panel

Product Overview

The EP DROP 1-2 is an electronic control panel specifically designed for rainwater harvesting systems. It ensures the emptying of rainwater tanks by utilizing a rain sensor. When a meteorological event occurs, the rain sensor connected to the panel activates the emptying pump after a set time. The EP DROP is compact, economical, and easy to install and program, facilitating the replacement of older control panels.
