™
4G
INSTALLATION MANUAL
DESCRIPTION
IL PL mode
Inline system for pressurized line water source
Operating principle:
The pressure differential required to generate fertilizer suction via the Venturis
is produced by a booster pump integrated in the NetaJet™ 4G. This mode of
operation, where the lower manifold is at low pressure (around 0 bar/psi), allows
the use of high-efficiency Venturis with high suction capacity and low motive flow consumption.
Since all the main line water flows through the system, slight pressure losses at the NetaJet™ 4G outlet
should be considered (see the table below).
Suitable for main line flow rate:
Up to 20 m³/h (90 GPM)
Suitable for main line pressure:
•
Standard: 2.5-5.8 bar (36.5-84.0 PSI)
•
High pressure: 5.8-7.5 bar (84.0-108.5 PSI)
Dosing channels:
Accommodates a wide variety of highly accurate dosing channels for fertilizer and concentrated/diluted acid:
•
Up to 5 x 50-400 l/hr (13-105.5 GPH)
•
Optional - Concentrated acid channel, 50 l/h (13 GPH)
Total fertilizer/acid suction capacity - up to 2000 l/h (528 GPH).
Controller:
NMC-Pro (Operation with third-party controllers is optional. Consult Netafim™.)
EC/pH:
Precise single or dual monitoring and control - selectable by customer.
