UniGray™ CNL & HCNL

Solar-radiation deflecting dripperline with non-leakage features for high performance pulse irrigation systems in greenhouses and soilless crops.

In addition to delivering absolutely uniform irrigation of water and nutrients and enabling pulse irrigation, UniGray™ CNL & HCNL PC drippers with solar-radiation deflecting tubing help maximize light and thermal efficiency in greenhouses, soilless cultures, nurseries and pot irrigation.

Perfectly uniform water distribution during intensive or pulse irrigation
Anti-Drain (CNL & HCNL) mechanisms eliminate “drainage & refill” effect

Why UniGray™ CNL & HCNL?

Efficient pulse irrigation: When pressure drops at the end of an irrigation cycle, the CNL/HCNL mechanism closes the dripper keeping pipes full of water ensuring uniform irrigation during short cycles.
Solar-energy deflecting pipes: Light-colored dripperlines are designed to prevent absorption of sunlight, in order to optimize available radiation for photosynthesis.
Anti-clogging: Anti-Siphon mechanism blocks suction of dirt and other contaminants into the dripline during system draining - eliminating the risk of clogging, or partial clogging.
Uniform flow rates: Industry’s biggest filtration area and water passage assures 100% uniformity of water and nutrient distribution even in long laterals and complex topography.
Optimal performance: Self-flushing system continuously flushes out debris to ensure optimal dripper performance year after year.
Root protection: A physical barrier stops root intrusion without reliance on chemicals.
Long-lasting: Ultra-durable, UV-stable lines are built to resist damage from heavy machinery, soil insects, sun exposure and re-coiling.
