EP DROP 1-2: Electronic Control Panel for 1 or 2 Pumps in Rainwater Harvesting Tanks
The EP DROP 1-2 is a specialized electronic control panel designed for rainwater harvesting systems. It ensures the automatic emptying of the collection tank after a rainfall event. The integrated rain sensor initiates the pump's emptying cycle after a programmed time following the meteorological event.
This control panel is compact, economical, easy to install, and program, making it a suitable replacement for older control units.
