MICRO-SPRINKLERS/EMITTERS ASSORTMENT

WARNING

When handling acid, always observe the product safety instructions and avoid acid coming in
contact with the crop, the soil/substrate and the environment.

•

Micro sized droplets, at a relatively low pressure of 4.0 bar the CoolNet Pro™ uniformly distributes an

average droplet size of 65 micron.

•

Specially designed for cooling, humidifying and rooting tables.

•

It is strongly recommended to connect the CoolNet Pro™ to the distribution pipe with a SSPE (super soft PE)

micro-tube, a specifically designed stabilizer and AD (anti-drain) valve that will prevent distribution pipe
drainage.
