GrowoniX ROC-3 RO System Controller for Light-Commercial Setups
The ROC-3 is the brain for monitoring and controlling a light-commercial reverse osmosis system. It provides relays for the RO booster pump, inlet solenoid valve, and membrane flush solenoid valve, and ships configured for a 120VAC supply with terminals for clean wiring. Dry-contact inputs watch storage tank level, the low-pressure switch signal, and a system lockout for pretreatment backwash or regeneration, and every input and output runs on time delays so the sequence fires in the right order instead of all at once.
Automatic Membrane Flush Valve That Extends Membrane Life
The included flush valve is what sets this build apart. The ROC-3 triggers an automatic membrane flush at startup, shutdown, and at timed intervals, sweeping the concentrated reject water off the membrane surface so scale and fouling don't build up between runs. It's fully programmable with up to four separate programs, so you can tune flush timing and pump behavior to your source water and duty cycle. Wire it once at the inlet and pump, set your programs, and the controller handles the flush routine that growers otherwise forget to do by hand.
Key Features
- 120VAC Supply & Terminals: Wired for a standard 120VAC feed with terminal connections for booster pump and solenoids.
- Membrane Flush Valve: Automatic flush at startup, shutdown, and timed intervals to clear reject water off the membrane.
- Three Relay Outputs: Controls the RO booster pump, inlet solenoid, and membrane flush solenoid.
- Dry-Contact Inputs: Monitors tank level, low-pressure switch, and system lockout for pretreatment events.
- Programmable Logic: Up to four separate programs with time-delayed inputs and outputs for proper sequencing.
