The i-Wob is Senninger’s top-selling pivot sprinkler. It instantly and uniformly covers the entire area of its wetted circle with consistently sized droplets. This consistent droplet size maintains the sprinkler’s pattern integrity and helps prevents wind-drift and evaporation.
• Ideal for flexible hose drops
• Low application intensity to help reduce soil compaction and runoff
• Instantaneous 360-degree application pattern
• 4 models available with diverse trajectories and droplet sizes
• Exclusive below-the-nozzle weight eliminates the need for heavier, conventional drop weights
Helps keep the i-Wob and other pivot applicators stable on flexible hose drops. It threads securely into the bottom of the i-Wob and can remain on the applicator during nozzle changes. The weight’s UV-resistant thermoplastic construction prevents corrosion and deters metal theft due to its lack of metal parts.
UP3 Nozzles simplify renozzling. Nozzles are removed in four easy steps: simply pinch and pull to remove the nozzle; then place and click to re-install. There is no need to disassemble the sprinkler to reach the nozzle. Plus, with the UP3 design, the i-Wob base is now an integral part of the bracket.
Used to increase the i-Wob’s area of coverage and position drops for precise irrigation. When combined with the Truss Rod Slings, the i-Wob can be set to hang at a precise location along the truss rod without hindrance or kinking. This reduces pattern interruption from colliding streams and allows growers to adjust sprinkler spacing.
Senninger pressure regulators limit excessive and varying inlet pressures to a constant outlet pressure. The outlet pressure can be matched to a sprinkler's design pressure regardless of the inlet pressure. Pressure Regulators help maintain sprinkler pattern integrity, distribution uniformity and performance.
Frequently Asked Questions
Both the i-Wob and the Xi-Wob provide instantaneous, uniform coverage over their entire wetted area.
The i-Wob was made exclusively for flexible hose drops while the Xi-Wob was made for semi-rigid, steel and PE drops. However, those that prefer the Xi-Wob can also use it on flexible hose drops as long as it's installed with a drop weight like Senninger's Magnum Weight.
Selecting the correct sprinkler is much more complex than simply determining how far a sprinkler can reach or what color plate goes with what crop.
Irrigators need to consider a sprinkler’s droplet size and their field’s soil texture when making a buying decision to avoid:
• Wind-drift and evaporation
• Surface soil compaction or sealing
• Infiltration reduction
• Runoff and erosion
Water can alter the soil's structure and infiltration rate. To keep soil close to its pre-irrigation state, water should be distributed instantaneously over a large area of coverage and with low application intensity.
Selecting an adequate droplet size according to your soil texture helps soil maintain its structure. A basic rule to follow is, the lighter the soil, the larger the droplet; the heavier the soil, the smaller the droplet. Droplets that are too large and are concentrated in specific areas can cause surface sealing and lead to erosion or inefficient irrigation.
Providing the largest area of instantaneous coverage possible helps reduce the impact of a sprinkler's application pattern on the soil and crop. This critical aspect of sprinkler performance is similar to the need for wide tires on farm equipment to reduce soil compaction.
The i-Wob is capable of distributing water at a rate that closely matches a soil’s infiltration rate, thus, it helps maximize irrigation efficiency and minimize erosion.
When installing the i-Wob, Senninger recommends using two feet of reinforced flexible hose, which is critical to reducing vibration.
For optimal performance on high profile crops such as corn, i-Wobs can be spaced to the maximum factory specified spacing on the first two spans on a 7 tower 1/4 mile machine. Limit spacing to 11' ft (3.4 m) after that criteria has been met. For low-lying crops, maximum spacing can be extended further down the system. Shorter and longer machines can use the maximum recommended spacing on 25% of the total machine length.
Close Spacing with Bubblers
Texas farmers are mounting Bubblers with just 30 inch spacing between heads and maximizing their water usage with a combination of LEPA (Low Energy Precision Application) sprinklers and conservation tillage practices.
