Flow-regulated dripper UniRam™ HCNL

pressure-compensatedanti-drainagefor greenhouse

Product overview
Integral pressure‑compensated dripper with built‑in anti‑siphon and anti‑drain mechanisms and continuous self‑flushing. Designed for greenhouse, deciduous plantation and tree irrigation, and for permanent installations requiring intensive scheduling and reliable performance across variable topographies and water qualities.

Suitable crops

• Blueberries
• Cocoa
• Greenhouse cucumbers
• Greenhouse tomatoes
• Olive
• Table grapes

Benefits & features

• Pressure‑compensated — delivers precise and equal amounts of water across a wide pressure range to ensure uniformity along laterals.
• Anti‑siphon mechanism — prevents contaminants from being drawn into the dripper, enabling safe subsurface use.
• Anti‑drain mechanism (HCNL) — eliminates drainage and refill effects to improve pulse irrigation efficiency on steep slopes.
• Continuously self‑flushing — purges debris during operation to maintain reliable function with challenging water sources.
• Physical root barrier — design prevents root intrusion into the labyrinth, reducing blockage risk.
• Hybrid outlet — welded, detachable outlet that provides superior clogging resistance and prevents drop migration; supplied pre‑installed for quick setup.

Installation environment

• Suitable for on‑surface and subsurface installation
• Designed for long service life (10+ seasons with proper maintenance)
• Applicable to flat fields and installations with significant topographic differences
• Operates reliably in demanding water quality conditions
