MICRO-SPRINKLER/EMITTER SELECTION

Introduction

Netafim™ micro-sprinklers/emitters have been uniquely designed for upside-down installations, and
are the ideal solution for irrigation, cooling and humidity enhancing for protected crops in greenhouses,
tunnels, nurseries and net-houses. Our products enable unprecedented watering uniformity in both
standard full overlap installation and with our traditional "strip of micro-sprinklers/emitters".
The versatile Netafim™ line of micro-sprinklers/emitters covers a broad scope of applications; thereby
simplifying the design process. Whether you are designing a new application or retrofitting an existing
system, our micro-sprinklers/emitters offer highly reliable solutions for all your needs.

There is no doubt that in most cases plant irrigation and fertilization is much more efficient and effective
when accomplished using drip systems. However, there are situations in which the farmer will choose to
use micro-sprinklers to perform this action, especially with protected crops. For instance, when there is a
very large quantity of potted plants per unit area, or when the crop is particularly dense and reaching each
plant with dripperlines would not be cost-effective. In such cases, the irrigation system must provide very
efficient and uniform watering.
For this purpose, Netafim™ proposes a network of SpinNet™ bridgeless micro-sprinklers (see
placed upside down (in the vast majority of protected crop applications) and by full overlap between the
wetted patterns produced by each emitter to create a uniform "rain" over the entire area.
