UniRam™ CNL

UniRam™ CNL

UniRam™ CNL (Compensating Non-leakage) is an Integral Pressure-compensating, Continuously Self-cleaning Dripper with an Anti-siphon and Anti-drain Mechanism.


Open field, greenhouse, net house, soil and soilless media in situations which require pulse irrigation or where dripperlines need to remain full between irrigations.


  • Pressure-compensating range: 0.5 - 4.0 bar with 1.2 mm wall thickness and 0.5 - 3.5 bar with 1.0 mm wall thickness.
  • Anti-siphon and Anti-drain mechanism.
  • 4 flow rates: 1.0, 1.6, 2.3 and 3.5 litres per hour
  • The largest filter area at the inlet to each dripper. Recommended filtration: according to dripper's flow rate.
  • Double TurboNet™ labyrinth with large water passage.
  • Injected dripper, very low CV.
  • Injected silicon diaphragm.
  • UV resistant. Resistant to standard nutrients used in agricultural.
  • UniRam™ drippers meet ISO 9261 Standards with production certified by the Israel Standards Institute (SII).
  • Welded into thick-walled pipes.
  • 2 wall thicknesses, 2 diameters:


UniRam™ CNL Nominal diameter Wall thickness
UniRam™ CNL 17010 17 mm 1.0 mm
UniRam™ CNL 20010 20 mm 1.0 mm
UniRam™ CNL 17012 17 mm 1.2 mm
UniRam™ CNL 20012 20 mm 1.2 mm

Features and Benefits:

  • Pressure compensated: Precise and equal amounts of water are delivered over a broad pressure range. 100 % uniformity of water and nutrient distribution along the laterals.
  • Anti-Siphon mechanism : Prevents contaminants from being drawn into the dripper.
  • Anti-drain (CNL) system : Eliminates drainage and refill effect, and improves efficiency in pulse irrigation.
  • Continuously self-flushing : Flushes debris as it is detected, throughout operation, not just at the beginning or end of a cycle, ensuring uninterrupted dripper operation.
  • Self-flushing system with wide filtration area improves resistance to clogging thus making UniRam™ highly resistant when using poor quality water.
  • Physical root barrier : Better protection against root intrusion without reliance on chemicals.
  • TurboNet™ labyrinth assures wide water passages, large deep and wide cross section improves clogging resistance. Widest water passages within the dripper.
  • The water is drawn in to the dripper from the stream centre, preventing the entrance of sediments in to the drippers.
