UniRam™ CNL

The ideal dripperline for high-frequency (pulse) irrigation in greenhouses, soilless crops and orchards that require intensive irrigation scheduling

Featuring a special anti-drain and non-leakage (CNL) mechanism, UniRam™ CNL integral pressure compensated, self-cleaning drippers are designed to deliver precise pulse irrigation – for greenhouses, soilless cultures, nurseries, and fruit trees.

  •  Ensures perfectly uniform water distribution during pulse irrigation (irrigation in short, frequent intervals)
  • Eliminates drainage and refill effect that can cause non-uniform water distribution.

Why UniRam™ CNL?

  • 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, which is needed in sub surface applications.

  • Anti-drain (CNL) system: Eliminates drainage and refill effect, and improves efficiency in pulse irrigation.

  • Continuously self flushing: Continuosly flushing debris, 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 low quality water, which leads in reduction in filtraion requirements, hence increasing filtration efficiency.

  •  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.

Specifications of UniRam™ CNL

  • Flow rates: 0.70, 1.00, 1.60, 2.30 & 3.50 ℓ/h  

  • Pressure-compensating range: 1.0 – 4.0 bar.

  •  Anti-Siphon and Anti-Drain mechanism.

  • Largest filter in each dripper. Recommended filtration: 100 to 130 micron. Filtration method is to be selected based on the kind and concentration of the dirt particles existing in the water. Wherever sand exceeds 2 ppm in the water, a Hydrocyclone is to be installed before the main filter. When sand exceeds 20 ppm and when total suspended solids exceed 150 ppm, pre treatment will be applied according to Netafim™ expert team’s instructions.

  • Double TurboNet™ labyrinth with large water passage.

  • To be “welded” into thick-walled dripperlines (1.00, 1.20 mm).

  •  Injected dripper, very low CV.

  • Injected silicon diaphragm.

  • High UV resistance. Resistant to standard nutrients used in agricultural.
