Spray vehicle speeds range from 1-60 mph, a 6000% difference. Fixed orifice nozzles adjust only within a small faction of this enormous range.
With the factory calib
rated nozzles, there are no over- or under - application problems. No longer will accidents be caused by excessive slippery chemicals left on the roadway.
Slow-moving spray trucks will not be enveloped in a cloud of spray, tempting drivers to use risky passing behaviors. O-Nozzles spray backwards from the fast moving truck, thus cancelling its forward motion. The Zero Velocity solid streams fall gently to the road without atomizing or fogging. Other cars on the road will not have their visibility reduced while spraying occurs.
For Prewetting, it is now possible to accurately control pre-wet rates to precisely match salt spreading rates. Without the O-Nozzle, prewetting is erratic. Salt becomes too wet at low speeds and is poorly wetted at high speeds.
Dust and Erosion Control for Roads and Highway Shoulders
Frequent and intensive spraying is often needed to reduce pollution from dust under new air quality standards. Precise liquid metering at any speed with O-Nozzles lets crews finish jobs more quickly, cover more miles per day. If desired, very high GPLM rates can be achieved.
Airport Anti-Icing /De-Icing
The new O-Nozzle is ideally suited for runways, taxiways, ramps and parking lots. O-Nozzles produce cohesive solid streams of de-icer that cover wide areas. O-Nozzle systems are designed for high speed spraying, minimizing airport operations downtime.
One airport manager reports that his new O-Nozzle spray truck is able to finish runway de-icing and park back in the same amount of time it took his earlier multi-boom system to unfold, set up and get into position, ready to spray.
Soil Compaction and Ground Stabilization for Gravel Roads
Building a road is a layer-by-layer process with accurate application of liquid binding agents needed to meet highway engineering specifications. Sprayer speeds vary widely, requiring uniform output at all times. Sprayers with O-Nozzles get the job done faster while consistently spraying at exact rates.
