2 PERFORMANCE: CLOSE SPACINGS Discover the difference closer emitter spacing can make to your crop. From greater system efficiency, to more uniform yields, close emitter spacing can help you boost your farm profits. Fortunately with T-Tape there is no additional cost for closer emitter spacing, allowing you to experience the benefits without the extra cost. BEST AGRONOMIC PERFORMANCE The benefits of closer emitter spacing are numerous, but are all related to more effective water movement. When irrigating, you want water to move laterally, not deep down through the soil profile where it is either lost (including any fertilizers added) or is harder for plants to uptake. By keeping emitters spaced at close intervals, water flows laterally quicker, ensuring a continued wet strip along the row. In addition, more emitters per meter provides greater protection against crop loss if an emitter becomes blocked. A great thing is when you use T-Tape, closer emitter spacing intervals do not need to come at an extra cost. Because Rivulis T-Tape has emitters manufactured into the tape itself, as opposed to inserted molded emitters, there is no cost difference per meter between 10 emitters per meter (10 cm spacing) and two emitters per meter (50 cm spacing). T-Tape helps make your choice of emitter interval spacing an agronomic decision, not one based on your bank account.

3 PERFORMANCE: ADVANCED ENGINEERING Water flows through supply tube & enters inlet filters Slit outlet opens when the system is pressurized to allow flow of water Inlets built into the tape act as micro-filters preventing certain contaminants from entering the emitter flow track Unique chevron design flow track creates a turbulent flow to provide excellent clogging resistance PERFORMANCE: CLOGGING RESISTANCE Most water will still contain foreign and organic particles even after it has been filtered. Therefore the design of the emitter is critical to help prevent clogging by stopping contaminants from entering the emitter. A unique feature of T-Tape is the high number of inlet filters each emitter contains. Every T-Tape emitter contains 13 to 211 inlet filters (depending on configuration). T-Tape requires just 5 inlet filters open to function correctly. Not only does this provide outstanding protection in every emitter, it also helps T-Tape perform in conditions where other drip lines may fail. Inlet filters * at 70 cm above ground level PERFORMANCE: INLETS Product* Spacing Emitter Flow Rate (cm) (l/h per emitter) Number of Inlets (per emitter) * The number of inlet filters does not vary between diameters of T-Tape. 500 series product is specified in this table, but the same specifications of inlet filters also applies to 700, 900 and 1100 series T-Tape where applicable. 3

4 PERFORMANCE: REINFORCED DESIGN Due to T-Tape s unique design, the tape is folded and welded over itself, in turn creating a strong seam along the entire length of the tape. Double thickness along the seam helps make T-Tape stronger and therefore easier to retrieve in the field. In addition, the seam provides an extra layer of protection to the emitter. T-Tape is designed to snap instead of stretch, with the seam design helping protect the in-built emitter from damage, both during installation and retrieval. EASY PRODUCT IDENTIFICATION Specifies the series and the diameter of the tape: 500 series, 5/8 (16 mm) Specifies the thickness of the tape: 8 thousandths of an inch (0.20 mm) Specifies the spacing between emitters: 30 cm Specifies the flow rate per 100 m of tape per 0.55 bar: 340 l/h per 100 m NO COMPROMISE: WIDE RANGE OF CONFIGURATIONS The problem with many drip systems is that you cannot always get the ideal configuration for your unique requirements. Therefore you compromise and in turn, may not achieve the optimum results possible. Compromise is not an issue when you choose T-Tape which features one of the widest ranges of configurations available including: 7 x Flow rate options from 0.25 l/h 4.0 l/h Choose depending on your individual crop, environment and soil requirements 4 x Diameters: 16, 22, 29 and 35 mm. Larger diameters allow for longer-run lengths while still achieving high uniformity 7 x Wall thickness options: 5 15 mil ( mm) Heavier wall thicknesses are ideal for multi-season, long-term sub-surface, or where additional strength is required 500 Series 16 mm ⅝ 700 Series 22 mm ⅞ 900 Series 29 mm 1⅛ 1100 Series 35 mm 1⅜ 4

5 INTRODUCING T-Tape S If you need even more tensile strength than T-Tape s already reinforced design, T-Tape S is your answer. Manufactured with some of the most advanced extrusion technology in drip irrigation, T-Tape S provides outstanding tensile strength making it ideal for situations where retrieval may be a challenge. T-Tape S is easily identified with its signature green stripe (Europe only). Competitor 1 T-Tape T-Tape S (lbf) PRODUCT GUIDELINES T-Tape can perform at low pressure and therefore flow rates are calculated at 0.55 bar. In some cases, you may increase pressure, which will in turn provide a higher flow rate from each emitter. For example, if you run T-Tape with 0.50 l/h emitter at 0.80 bar, each emitter will emit 0.62 l/h. The table below provides a reference of the output per emitter of T-Tape at 0.55, 0.80 and 1.00 bar. Emitter Flow Rate (l/h) Based on Nominal Pressure of 0.55 bar Flow rate (l/h) per 0.80 bar Flow rate (l/h) per 1.00 bar COMMON FILTRATION REQUIREMENTS FOR MOST APPLICATIONS > 0.5 l/h per emitter: 130 micron / 120 mesh 0.5 l/h per emitter: 100 micron / 150 mesh Filtration requirement is dependent on a number of factors including water source and application. Please consult with an irrigation specialist for filtration requirements for your specific application.
