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.


  • Variety of flow rates: 5 different flow rates (0.7, 1.0, 1.6, 2.3, 3.5 L/H) can address any condition or application
  • CNL range: 1.0 – 4.0 bars / HCNL range: 1.5 – 4.0 bars
  • Wide range of pipe diameters: 16.0 - 23.0 mm
  • Wall thickness: 0.9mm, 1.0mm, 1.2mm
  • Superb UV resistance and unique internal black layer that prevent micro-organizem and algae development
