• Pressure compensated dripper with anti-drain feature

Applications: 

• Greenhouses, nurseries, citrus, orchards, deciduous and tree irrigation.

Specifications:

• Working pressure in the Low CNL model - 1.0 to 4.0 bar
• Working pressure in the High CNL model - 1.4 to 4.0 bar
• Turbulent" labyrinth with largest water passages.
• 3 different flow rates in each of the different models (LCNL and HCNL)
• To be “inserted" into thick-walled pipes (0.9, 1.0 and 1.2 mm.)
• Injected dripper, very low CV.

Features and Benefits:

• PC system, patented pressure differential system maintains uniform flow rate at different inlet working pressure (in the recommended working pressure range), ensuring exact distribution of the water and fertilizers.
• Self-flushing system, improved resistance to clogging.
• Anti drain (CNL) system, eliminates drainage and refill effect, improves efficiency in pulse irrigation.
• Dripper can be positioned exactly where required.
• Number of drippers can be increased so as to increase water quantity supply aimed at meeting tree growth rate requirement.
• Allows the installation of "spider assembly", splitting the drip supply to a number of drip outlets.

 Within the working pressure range

• When inserting drippers in tubes with 0.9 mm wall thickness, the maximal working pressure recommended is 3 Bar.
• When inserting drippers in tubes with 1.0 mm wall thickness, the maximal working pressure recommended is 3.5 Bar.
• When inserting drippers in tubes with 1.2 mm wall thickness, the maximal working pressure recommended is 4 Bar.
