IRIS Thin-Wall Drip Tube 16 mm x 0.25 mm (10 mil) x 33 cm, 1.0 L/h, 500 m

IRIS emitter – compact, non-pressure-compensated and clog-resistant emitter for thin-walled drip tubes

The IRIS emitter is a modern, compact, flat single-insert emitter that has been specially developed for thin-walled drip tubes – primarily for use in field vegetable cultivation. Despite its small size, IRIS is designed for demanding conditions and varying water qualities, while enabling optimal line lengths for irrigation.

Thanks to its wide labyrinth channel and turbulent flow inside, IRIS reduces particle settling and – with proper filtration – is considered one of the most clog-resistant emitters in its class. This makes it an excellent choice for anyone looking for a reliable and stable drip irrigation system with minimal maintenance.

Areas of application

The IRIS emitter is integrated into thin-walled drip tubes and is suitable for:

• Field crops (vegetables, potatoes, corn, industrial crops, etc.)
• Row plantings in open fields
• Irrigation of pumpkin, melon, and annual berry crops
• Drip irrigation under plastic and mulch
• Drip irrigation systems in fruit and wine growing where thin-walled pipes are used (e.g., in the first years of cultivation)
• Smaller agricultural and professional operations looking for a temporary solution with the quality of a “full-fledged” drip pipe

Key advantages of IRIS

1. Compact, non-pressure-compensated emitter for thin-walled pipes
2. IRIS was developed specifically for thin-walled drip pipes and combines the cost-effectiveness of thin pipes with the reliability of a high-quality emitter. The emitter is an integral part of the thin-walled pipe and operates stably, even under demanding conditions.
3. High clogging resistance
4. The wide labyrinth channel and turbulent flow mode in the emitter reduce particle deposition and residue formation. This reduces the risk of clogging and keeps the flow rate stable throughout the entire service life with regular flushing.
5. Modern symmetrical design
6. IRIS has a symmetrical housing design (4D design) that ensures high geometric repeatability, precise positioning of the emitters in the pipe, and uniform operation of each emitter. For the user, this means a more homogeneous drip line and a more uniform irrigation pattern along the row.
7. Use with different water sources
8. IRIS is designed for water from different sources, provided that the recommended filtration is observed (tap water, well water, stored water, etc.).
9. Good irrigation quality along the line
10. The sophisticated internal geometry of the emitter ensures stable water delivery along the drip line, thus supporting a full irrigation result in crop management.

Important note on hydraulics

IRIS is a non-pressure-compensated emitter. This means that as the line length increases and the pressure drops along the drip tube, the water output of the emitters at the end of the line is lower than at the beginning of the line.

Therefore, when planning the system, it is important to:

• adhere to the recommended maximum line lengths;
• select the correct working pressure;
• take into account the terrain profile and pipe layout pattern.

With a professional hydraulic design, a system with IRIS emitters provides uniform and reproducible irrigation for most field and vegetable crops.
