PRINCIPLES OF OPERATION

Aqua-Traxx PC is a seam less, extruded drip tape with a molded emitter inserted in a

tube. The emitter is made up of the following:

• Filter inlets that which reduce the amount of debris that enter the emitter.

• Turbulent flow path.

• Pressure compensating chamber.

• Unique multiple laser slit outlets.

Seamless construction eliminates seam failures, and reduces the incidence of root

intrusion. Extrusion technology utilizes high-quality, extrusion-grade engineering

polymers renowned for their toughness and flexibility. These polymers were

developed specifically for use in harsh industrial and agricultural environments.

The exclusive flowpath molding process creates cris p, well-form ed physical features,

resulting in excellent repeatability and high emission uniformity (EU). The

turbulent flowpath design reduces clogging in the flow channel. Pressure

responsive section provides a relatively constant flow rate within the operating

pressure range allowing for longer lengths of run and/or significant elevation

changes. (Flow exponent of 0.2).

Aqua-Traxx PC emitter As shown above, water enters the flow path through the filter
inlets which are shaped like a reverse funnel. This keeps debris to the outside of the
emitter where it can be flushed away. Next, the water flows through the turbulent
flow channel before entering the pressure responsive section. The pressure
responsive section responds to changes in water pressure to maintain a constant flow
throughout the operating pressure range. Finally, the water exits through the laser­made multiple slit outlets to the crop. The multiple slits ensure the proper function
of the emitter and also provide the added benefit of significantly reducing the effect
of water running down the tube on slopes.

FEATURES AND ADVANTAGES

• Precision molded emitter for high uniformity.

• Seamless construction for greater reliability.

• Multiple laser slit outlet Reduces startup clogging and impedes root intrusion.

o Dramatically reduces the water running down the tube on slopes.

• Turbulent flow path provides reduced clogging.

• Pressure compensating chamber provides increased Emission Uniformity

(EU) throughout the operating pressure range.

• Available in a wide range of wall thicknesses, outlet spacings and flow rates.

• Highly visible blue stripes for quality recognition and Emitter UP indicator.

• Superior tensile and burst strength.

• Tough, abrasion-resistant material reduces field damage.

USE AND SELECTION

Wall Thickness

8 mil - Intermediate products for general use in longer-term crops and average soil
conditions. Has an operating pressure range: 4 to 16 psi.

10 -15 mil - Heavy wall designed to be used in rocky soils, where insects and animals
may cause damage, or where the tape is to be used for more than one season.
Increased wall thickness provides for a wider operating pressure range. (See
specifications for mil thinness vs. operating pressure range.)

Spacing

6 and 8 inch - Used in closely spaced crops, on sandy soils, or where higher flow
rates are desired.

12 inch - Used on crops in medium soils and average crop spacings.

16 inch - Used on wide spaced crops where a longer length of run is desired.

24 inch - Used for widely spaced crops, heavy soils, long run lengths.

Flow Rate

0.27 gph Flow - Normally recommended for most crops and soils.

0.20 gph Flow - Recommended for longer runs on most crops and soils.

Diameter

5/8” - Used for average run lengths (0 to 1,000 ft).

7/8” - Used for long run lengths (up to 2,500 ft).

Slopes

Aqua-Traxx PC can be used in downward sloping, undulating or flat topographical
conditions. The pressure compensating feature allows for an operating pressure
range from 4 psi to 25 psi depending on the wall thickness. Use Aqua Flow program
for detailed hydraulic information.
