News IRRIGAZETTE N 73 - Lowest Flow (than AquaTraxx-Toro and T-tape) PATHFINDER Labyrinth HDPE Drip Tape 6mil Path 3000

Specifications

PATHFINDER is a brand patented, bought from Nelson Irrigation USA and produced in Spain

• We are producing in Spain for: Europe, America, Africa, Asia and Oceania.
• The manufacturing process results in the largest low flow path in the drip industry and is more plug resistant than competitive tape emitters.
• Pathfinder is available in different wall thickness,flows and spacing.
• Patented clear flow path enables periodic monitoring of Path.
• Pathfinder can be installed on the surface, null a wire, or buried.
• Pathfinder is manufactured with materials of high quality that provides resistance to agricultural chemicals and abrasions during handling. The manufacturing process results in the largest low flow path in the drip industry and is more plug resistant than competitive tape emitters. The drip tape is used to irrigate crops horticultural and industrial tomatoes, strawberries, peppers, melon, potato, squash, lettuce, eggplant ...

Available in thicknesses 6000 (0.15 mm or 150 microns); rolls of 3200 meters and 8000 (0.2 mm or 200 microns); rolls of 2500 meters.

We recommend Pathfinder as has quality level of AquaTraxx and T-tape. In this study (IRRIGAZETTE N°73 - NOVEMBER/DECEMBER 2002) you can see we are superior in strength, durability, distribution uniformity and reliability:
