Flow-regulated dripper UniGray™ CNL & HCNL

pressure-compensatedanti-drainagefor greenhouse

Product description
Integral pressure-compensated dripper with continuous self-flushing, anti-siphon and anti-drain mechanisms, designed for greenhouse and permanent intensive irrigation. Light gray dripline reduces solar radiation absorption to limit heat buildup and algae growth.

Suitable crops

• Blueberries
• Greenhouse peppers

Benefits & features

• Pressure-compensated - Delivers consistent flow rates across a wide pressure range to ensure uniform water and nutrient distribution along laterals.
• Anti-siphon mechanism - Prevents ingress of contaminants, enabling safe use in subsurface or variable installations.
• Anti-drain mechanism (CNL & HCNL) - Eliminates drain-and-refill effects, improving pulse irrigation performance and reducing water loss on sloped terrain.
• Continuously self-flushing - Keeps the labyrinth clear by flushing debris during operation, reducing clogging risk with challenging water quality.
• Physical root barrier - Labyrinth design includes a root barrier to limit root intrusion and preserve flow stability.
• Wide filtration area - Large inlet filtration reduces sediment entering the labyrinth under harsh water conditions.

Installation environment

• On-surface installation
• Engineered for more than 10 seasons of service with proper maintenance
• Suitable for flat fields and sites with topographic differences
• Operates reliably with challenging water quality
