02 / FERTIGATION SYSTEMS
Choose for the duty.
Control for the crop.
Fertigation machines for greenhouse nutrient dosing, EC/pH monitoring and irrigation control. Start with your water flow, stock solutions and growing method.

WHAT A FERTIGATION SYSTEM DOES
Coordinate dosing
and irrigation.
A fertigation system introduces nutrient stock solutions into irrigation water and controls their delivery to the crop. Yunxue equipment combines dosing channels, recipe management, EC/pH monitoring and irrigation-control functions.
Selection starts with the required operating range, not greenhouse area alone. Water chemistry, nutrient concentration, irrigation zones and control architecture all affect the final specification.
REFERENCE CONFIGURATIONS
A starting point for selection.
The following configurations are drawn from Yunxue’s published product information. Confirm the current hardware version, rated operating range and project-specific options in your quotation.
| Model | Mixing configuration | Published flow range | Stock-solution channels | Published pipe designation |
|---|---|---|---|---|
| GXF63A5 | Mixing tank | 0–20 tonnes/hour | 5 | DE63 |
| GXF110C5 | Inline mixing | 0–60 tonnes/hour | 5 | DE110 |
| GXF140C7 | Inline mixing | 0–80 tonnes/hour | 7 | DE140 |
Published flow ranges are reference figures, not a guarantee of minimum controllable flow or performance at every operating point. Confirm the required flow and pressure, chemical compatibility, stock-solution strength and dosing capacity. Different models and control versions may have different EC performance.

FOUR QUESTIONS THAT SHAPE THE DESIGN
Specify the operating conditions.
How much water runs at once?
Provide the required minimum and maximum flow, simultaneous zones and pressure at the point of delivery.
What goes into the water?
List stock solutions, source-water EC/pH, target EC/pH and acid-dosing requirements.
How is irrigation triggered?
Discuss scheduling, light-based or soil-moisture-based operation, valve count and integration with existing controls.
What must be verified?
Agree the test procedure, sensor checks, acceptable steady-state variation and response to changing conditions.
LOOK BEYOND A SINGLE NUMBER
EC stability needs
test conditions.
A steady trace, a fast response and accurate measurement describe different aspects of a dosing system. Evaluate the installed configuration and operating conditions alongside any precision figure.

From engineering reference to project specification.
How do I select the right model based on flow, pressure, channels, and zones?
1) Flow rate: Sized to your peak simultaneous zone flow (e.g. GXF63A5 up to 20 m³/h; GXF110C5 up to 60 m³/h; GXF140C7 up to 80 m³/h).
2) Pressure & mixing: Choose inline direct mixing for pressurized mains, or atmospheric mixing tank systems where raw water header pressure is fluctuating or low.
3) Dosing channels: 5 channels for standard A/B nutrient stock solutions + acid/alkali; 7 channels for multi-recipe, micronutrient, or multi-stage crop recipes.
4) Zones & control: The machine PLC can control irrigation zone solenoid valves directly (with expansion cards) or accept external run commands from your greenhouse climate controller.
Can I buy a standalone fertigation machine, or must I buy a complete package?
Both options are available. You can purchase a standalone skid-mounted fertigation machine with integrated controller, ready to tie into your existing supply and discharge piping. Alternatively, we supply turnkey packages including storage tanks, sand/disc filters, booster pumps, and electrical cabinets.
What information is needed to upgrade or replace an existing greenhouse dosing machine?
When replacing an existing machine (such as upgrading older domestic or imported units), provide: 1) Existing main supply pipe size (DE/DN), operational flow rate and water pressure; 2) Available power supply (voltage, Hz, phase count); 3) Current field valve voltages (e.g., 24VAC, 12VDC, 220VAC) and zone count; 4) Water source analysis (raw EC/pH); 5) Photos and schematic of your existing pump room manifold.
How are installation, commissioning, training, and warranty responsibilities divided?
Yunxue supplies factory-assembled and tested fertigation skids, detailed electrical schematics, hydraulic integration drawings, and bilingual operating manuals. Physical piping installation and electrical line connections are performed by the client's local contractors. Yunxue provides remote video commissioning support and technical training for your greenhouse operators. Overseas on-site dispatch is subject to specific contract agreement.
Is the same EC precision available on every model and operating condition?
No. Do not assume that one workshop test demonstration applies universally. Model architecture (mixing tank vs inline injection), controller version, water quality, stock-solution concentration, sensor calibration, and flow stability all influence field results. We define performance criteria for the specific configuration quoted.
What information is needed to receive an exact quotation?
Send your country/region, crop type, total area, irrigation method (drip, ebb-and-flow, hydroponic trough), peak irrigation flow, head pressure, stock-solution channel count, power grid specifications, and whether you require standalone equipment or a full coordinated package.
