Looking for a better way to manage your irrigation system’s water usage, eliminate runoff and reduce water costs? There’s a simple answer: switching to Toro’s Precision Series Spray Nozzles. These one-of-a-kind nozzles can help you save money and labor with the following advantages:
Precision Series Spray Nozzles feature patented H20 Chip
Technology that uses up to a third less water while achieving the same spray
distance as conventional spray nozzles.
Conventional fixed spray nozzles direct water by deflecting
it off of a plate at the top of the nozzle to create a fan-like pattern. With
H20 Chip Technology, specially designed chambers emit micro streams of water
that oscillate back and forth at a rate of nearly 200 times per second. The
result is larger, more uniform-sized droplets, class-leading coverage of the
irrigated area and better-defined edges.
Think of it this way: The difference between conventional
spray nozzles and Precision Series Spray Nozzles is like the difference between
placing your thumb over the edge of a garden hose versus whipping it back and
forth (except on a much smaller, much faster scale).
Lower Precipitation Rate
All Precision Series Spray Nozzles have a matched
precipitation rate of 1 inch (25 mm) per hour. That means all the nozzles,
regardless of radius, water at the same rate. Whether the zone is 5 or 15 feet
across, you can run the nozzles for the same amount of time to apply the amount
of water needed.
How does this compare to other leading nozzles? A typical
multi-stream rotary nozzle delivers good coverage, but the precipitation rate
is around 0.4 inches (10.2 mm) per hour. That means you have to run your
irrigation zone 2.5 times longer to apply the same amount of water. If you’re
in an area with “water windows” that require irrigation to be completed between
specified times, scheduling becomes a significant challenge. That’s one example
where a 1-inch-per-hour precipitation rate is an advantage.
Another benefit of a Precision Series Spray Nozzle versus a
multi-stream rotary nozzle is that the spray radius is fixed. If, for example,
you replace a 15-foot (4.57 m) conventional nozzle with a 15-foot (4.57 m)
Precision Series Spray Nozzle, no adjustment is needed. However, if you replace
it with a multi-stream rotary nozzle, you’ll have to adjust the radius on each
nozzle to achieve the needed head-to-head coverage — and that equates to
additional time and labor from a retrofit or installation perspective.
If you have a conventional fixed spray nozzle, you can pull
it out and replace it with a Precision Series Spray Nozzle without having to
change your runtimes. So, how is that possible with a third less water? The
answer is coverage, or distribution uniformity — in essence, how much water is
actually reaching the intended target. Distribution uniformity (DULQ) for
Precision Series Spray Nozzles averages in excess of 70 percent. With
conventional spray nozzles, it’s closer to 55 percent.
Integrated Pressure Compensation
In addition to the above benefits, Precision Series Spray
Nozzles are available with an optional, factory-installed pressure compensation
disc. When installed on systems with operating pressures in the 45-50 psi
range, the integrated pressure compensating disc presents an optimal 30 psi to
the nozzle. This allows the nozzle to maintain a 1-inch-per-hour precipitation
rate while reducing misting and atomizing, and can, in some cases, minimize the
need for a pressure-regulating spray body.
At Toro, our commitment to using water responsibly isn’t
limited to the products we make. That’s why we offer Precision Series Spray
Nozzles in both Toro (male) and female thread patterns for compatibility with
most other manufacturers’ spray bodies. Whether it’s a new installation or
retrofit project, you can take advantage of Precision Series Spray Nozzles to
increase efficiency. Plus, both thread pattern styles have the same list price;
we don’t charge a premium for the non-Toro option.
Third-party testing has confirmed that Precision Series
Spray Nozzles are the most efficient fixed spray nozzle on the market today, in
terms of both distribution uniformity and water usage. That makes Precision
Series Spray Nozzles ideally suited for growing turf.
