The Neptune Systems DŌS Dosing and Fluid Metering System is a popular automatic dosing system that is a perfect fit for the Controller Cabinet when combined with the DŌS faceplate. You’ll be able to hide the unit inside the stand for a cleaner and safer install. The cutout in the faceplate fits the DŌS like a glove. The two dosing heads and two buttons on the front of the DŌS are easily accessible. There are two thin slotted cutouts on the bottom of the faceplate to run the tubing from your DŌS back inside the cabinet. This results in a cleaner, safer, and more custom look for your Neptune Systems gear.
