Description
The J series single-channel fertigation unit is a pump-injection configuration for commercial irrigation projects. It has one injection channel and timed-start functionality, with EC/pH sensing listed as optional. It is intended for irrigation contractors, equipment distributors and orchard or hillside project buyers whose dosing requirements can be served by a single-channel arrangement.
Applications
- Orchard or hillside irrigation projects requiring a specified pump-injection unit.
- Timed injection of a compatible stock solution through one channel.
- Equipment procurement where optional measurement and commissioning scope are agreed before purchase.

Single-Channel Fertigation Unit Selection
Choose a single-channel arrangement when the project can use one stock-solution injection path. It does not provide simultaneous independent dosing from several stock tanks. If a nutrient recipe requires separate incompatible concentrates or independent acid dosing, review a multi-channel configuration. Optional EC/pH sensors do not by themselves establish closed-loop dosing: the control algorithm, sensor placement and mixing arrangement must also be confirmed.
Technical Configuration
Listed values describe the available configuration. Confirm the current datasheet, dimensional drawing and itemized supply scope before ordering.

Installation and Integration Checks
- Provide mainline flow and pressure, desired injection rate and stock-solution properties. Pump duty must be matched to the actual installation; a pump’s listed flow/head is not a guaranteed complete-system duty point.
- Confirm chemical compatibility, filtration, backflow protection and the proposed installation diagram.
- State whether EC/pH monitoring is required and whether the project needs display-only measurement or verified feedback control.
- Confirm local electrical supply, installation responsibilities, commissioning, sensor calibration and spare-parts scope.
- Confirm the selected valve-control interface. Any remote service requires destination connectivity, platform language and account-access review.
Frequently Asked Questions
Are EC/pH sensors included as standard?
No. They are listed as optional for this series. The quotation must identify which instruments and supported functions are supplied.
Is this equivalent to a multi-channel EC/pH fertigation system?
No. This unit provides a single pump-injection channel. Multiple independently dosed concentrates or acid circuits require a separately specified arrangement.
What injection rate should I use for design?
Request the current operating range and pump curve, then check against mainline pressure and the stock solution. The available brochure figures do not establish a guaranteed operating envelope.
Can it run on a different mains voltage?
The listed supply is AC 380 V, 50 Hz. Do not assume other voltages or frequencies are supported; request a confirmed export electrical configuration.
