Rain Bird HE-VAN nozzles offer even coverage throughout the spray pattern, delivering a healthy, beautiful landscape. Gentle close-in watering eliminates dry spots around the spray head. HE-VAN nozzles also generate large wind-resistant water droplets that prevent misting and airborne evaporation so the right amount of water is delivered to the right place.
The high efficiency of the HE-VAN nozzle allows you to shorten your sprinkler run times by up to 35%, saving you water and money. Even coverage makes them the perfect choice for homeowners looking to conserve water while maintaining a healthy beautiful landscape.
Distribution Uniformity (DULQ): DU in irrigation is a measure of how uniformly water is applied to the area being watered. DULQ is calculated by taking the volume in the lowest quarter of catch can measurements and dividing it by the average volume of all catch can measurements. Scheduling Coefficient (SC): SC is a measure of how long a zone must be run in order to provide adequate water to the driest spot.
