Yunxue Fertigation Machines for Greenhouse EC/pH Control
Choose for the duty. Control for the crop.
Yunxue Technology is the English marketing brand of 云靴科技（杭州）有限公司. Yunxue fertigation machines use a Yunxue-developed controller; GXF110C5 is the primary option for selection.
Fertigation machines for greenhouse nutrient dosing, EC/pH monitoring and irrigation control. Start with your water flow, stock solutions and growing method.
Consider GXF75C4 for a lower-cost configuration, or GXF140C7 for a larger flow requirement and more stock-solution channels.
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.
CURRENT MODEL SELECTION
Compare the three GXF options.
Specifications below come from the manufacturer-supplied GXF series sheet. Confirm the supplied hardware revision, operating conditions and project options in the quotation.
On small screens, scroll horizontally to compare all three models.
| Specification | GXF110C5 | GXF75C4 | GXF140C7 |
|---|---|---|---|
| Selection role | Primary option | Lower-cost option | Larger-flow option |
| Published water flow (t/h) | 0–60 | 0–25 | 0–120 |
| Stock-solution channels | 5 | 4 | 7 |
| Stock-solution flow per channel (L/h) | 0–700 | 0–450 | 0–700 |
| Inlet/outlet main-pipe outside diameter | 110 mm | 75 mm | 140 mm |
| Main-pipe connection | Flange | Flange | Flange |
| Dimensions: L × W × H (m) | 1.3 × 1.3 × 1.5 | 1.1 × 0.8 × 1.2 | 1.3 × 1.4 × 1.65 |
| Approximate weight (kg) | 60 | 60 | 80 |
t/h means tonnes per hour; the source values have not been converted to m³/h. A zero endpoint is a manufacturer-stated range, not a verified minimum controllable flow. Pipe figures are outside diameters, not DN sizes; confirm the flange standard and mating dimensions for the project. The sheet does not identify weights as net or gross.
Controller and irrigation functions
- Yunxue-developed controller with formula-driven logic and drag-and-drop interface configuration.
- Yunxue-developed water-flow sensor with automatic compensation and control valves.
- Five AC 24 V irrigation solenoid-valve control outputs as standard, expandable to 64. These are separate from the 4, 5 or 7 stock-solution channels; confirm the required expansion hardware and field wiring.
- Automatic irrigation based on schedules, soil moisture, accumulated solar radiation and environmental factors.
- Remote maintenance support and support for drainage recovery and reuse.
The stated new-generation steady-state EC variation is ±0.03 mS/cm. Agree acceptance conditions for the supplied configuration; this is not an absolute sensor-accuracy specification or a guarantee across all operating conditions.
Earlier website configurations — historical reference
The retained table below is the earlier website record; its hardware revisions were not identified. It lists GXF140C7 at 0–80 tonnes/hour, whereas the supplied GXF sheet above lists 0–120 t/h. These are different source records: confirm the supplied revision and rated duty in the quotation rather than treating the figures as interchangeable.
| 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 |
GXF63A5 remains a historical mixing-tank reference. Its manufacturer-reported storage-tank result below 0.02 mS/cm is specific to that model and operating mode; it does not describe GXF75C4. See the EC record and model-specific limits.
Published ranges are reference figures, not a guarantee of performance at every operating point. Confirm 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?
Start with GXF110C5 (published water flow 0–60 t/h, 5 stock-solution channels). GXF75C4 is the lower-cost option (0–25 t/h, 4 channels); GXF140C7 serves larger-flow requirements (0–120 t/h, 7 channels). These values follow the supplied GXF sheet; the earlier website figures remain separately identified above. Confirm the required operating flow, pressure and mixing arrangement for the quoted configuration. The Yunxue-developed controller provides 5 AC 24 V irrigation solenoid-valve control outputs as standard, expandable to 64; valve outputs are distinct from stock-solution channels. Confirm expansion hardware and any interface to existing greenhouse controls for the project.
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.
