UniRam™ HCNL

Integral pressure-compensated drip line, ideal for greenhouses, deciduous plantations and tree irrigation, and permanent applications (10 or more seasons) that require intensive irrigation scheduling in complex topographies.

The UniRam™ HCNL integral pressure-compensated drip line with Anti-Drain mechanism, for intensive irrigation applications in steep topography or long laterals.
Featuring a special Anti-Drain and Non-Leakage (HCNL) mechanism, UniRam™ HCNL integral pressure-compensated drip lines are designed to deliver precise pulse irrigation – for greenhouses, soilless cultures, nurseries, and fruit trees in complex topographies, and long laterals applications.

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

Why UniRam™ HCNL?

  • Strong Non-leakage: HCNL mechanism lets you install non-leakage systems in areas with steep slopes, where high shut-off pressure is required - avoiding flooding of the lower parts of your field
  • Better water and nutrient preparation: HCNL mechanism allows water and fertilizers to mix and circulate in the system prior to irrigation.
  • Anti-clogging protection: Anti-Siphon mechanism prevents suction of dirt and contaminants into the dripline during system draining - eliminating the risk of clogging or partial clogging.



  • Variety of flow rates: 5 different flow rates (0.85, 1.25, 2.0, 2.9, 4.4 L/H) can address any condition or application
  • HCNL range: 1.5 - 4.0 bar
  • Wide range of pipe diameters: 16.0 - 23.0 mm
  • Wall thickness: 0.9mm, 1.0mm, 1.2mm
  • Superb UV and chemical resistance
