Features

• 1. Equipped with a built-in touchscreen HMI, it features an elegant design, simple operation, and real-time display of operating status and fault information.
• 2. Water quality meets national standards for potable drinking water.
• 3. Overpressure protection for the high-pressure pump: when the outlet pressure exceeds 6.5 MPa, the system automatically shuts down and triggers an audible and visual alarm.
• 4. Low-pressure protection for the high-pressure pump: if the inlet pressure drops below 0.05 MPa due to insufficient pre-treatment supply, the system will automatically stop and activate an audible and visual alarm.
• 5. Fitted with a manual multi‑way valve, enabling convenient and rapid switching between filtration, backwashing, and forward flushing of the sand filter as needed.
• 6. The alarm system includes manual acknowledgment and mute functions.
• 7. Equipped with a reverse osmosis membrane cleaning system, capable of performing physical cleaning, concentrate discharge, chemical cleaning, and protective solution injection for the RO membrane elements.
