In 1981 Deeco Services Ltd established trading links with Israel to look to introducing their new micro sprinkler and drip irrigation technology.  This Irrigation technology development was pioneered by Naan Dan in the 1970’s with Dan’s micro sprinklers and Naan developing the world’s first cylindrical in pipe drip emitters.  This generated a worldwide revolution in irrigation techniques.

Working with the NZ Fruitgrowers Federation and Ministry of Agriculture, Deeco sponsored the costs of hosting two Israeli agronomists in NZ over a 5-year period in the mid 1980's.

Much has changed in the past few decades, with NaanDanJain becoming a global force in irrigation. With patented cascade dripper design to prevent clogging, their growth is led through innovation.

With over 100 drip line extruder options NaanDanJain provide an extensive range of dripline and button drippers widely utilised in New Zealand agriculture, horticulture, viticulture, landscape, and treated effluent disposal.

The Pressure Compensating Drip liners are available in Anti Siphon as standard in a range of flow rates and spacing’s to suit all applications.  With millions of meters of dripline in use, NaanDanJain driplines are a high quality, proven product for New Zealand conditions at an economical price.

With factory-trained engineers and in-house Irricad system design capability, operated by internationally recognised Certificate of Irrigation Design qualified design engineers, Deeco with NaanDanJain Irrigation is well established in New Zealand as the professional's choice for irrigation product and system design.

AmnonDrip PC, CNL & PC AS


Innovative, pressure-compensating (PC) dripline with special anti-syphon (AS) and compensating non- leakage (CNL) models, based on the Cascade labyrinth

  • Ideal solution for irrigation in topographically challenging terrain, and where long laterals are required
  • CNL option for pulse irrigation of orchards, open field crops and greenhouses
  • Subsurface Drip Irrigation (SDI), for accurate irrigation of orchards, open field crops and greenhouses

Main Features

  • PC AS: Pressure compensating anti-syphon design prevents suction at draining stage. Suitable for subsurface drip irrigation
  • Pressure-compensating non-leakage design reduces lateral filling time and facilitates pulse irrigation.
  • Efficient self-cleaning turbulence provided by the Cascade labyrinth
  • Hydrodynamic dripper design ensures continuousflushing of sediments and small dirt particles
  • Low CV for maximal uniformity
  • Weir structure improves root intrusion resistance and sand suction
  • 3D water inlet structure improves clog resistance
  • High-quality silicon diaphragm
  • Both carton and coil package options are available (see packing and shipping table)
  • Colored cap facilitates easy identification of dripper model
