22 FERTIKIT 3G INSTALLATION MANUAL
DESCRIPTION
PD mode
Operating principle: Utilizes the main line pressure
or gravity feed.
Saves the need for a dosing booster.
Also suitable for applications where there is no
electricity on the site (contact Netafim™).
Flow rate: 10 - 200 m³/h (44 - 880 GPM)
Suitable for main line pressure: 4.5 - 8.0 Bars (65 - 116 PSI)
Additional conditions:
For the dosing channels to provide proper suction, the pressure
downstream from the PRV should be at least 50% of the the pressure upstream
from the PRV (The eficiency of the Venturis decreases if this condition is not met).
In addition the system must supply suficient pressure for the field demand.
Dosing channels:
Accommodates a wide variety of dosing channels for fertilizer and concentrated/diluted acid:
• Up to 4* x 50 - 370 l/h (13 - 100 GPH) • Optional - Concentrated acid channel, 50 l/h (13 GPH)
.
Total fertilizer/acid suction capacity - up to 1480 l/h (390 GPH).
*If EC/pH is installed it occupies the location of one dosing channel (power required).
Controller: NMC-Pro, NMC-XL, NMC-Junior, NMC DC
(Other controllers or manual system without controller - optional).
EC/pH: None (Single monitoring only - optional)
