Benefits of oxygen nanobubble technology
Benefits farms can expect, based on oxygen nanobubble irrigation cultivation tests. Actual effects vary with crop and growing conditions.
Higher yield
Higher yield from the same growing area can increase shipments.
Higher product grade
A larger share of premium grades can earn higher selling prices.
Root development and early establishment
Healthier roots can support stable establishment and early growth after transplanting.
Higher sales and income
When shipments and selling prices rise together, farm sales and income can increase.
For reservoir-based agricultural irrigation
Applied where water is held in a tank or reservoir before irrigation. We check tank location, installation space and power conditions to advise on installation.

Please contact us for storage tanks or reservoirs larger than 500 m³
When Pongle L is a good fit
- Sites where the unit cannot go inside the tank because the water is shallow or the opening is narrow
- Tanks and reservoirs of 5–10 m³ (contact us for larger capacities)
- Sites with space outside the reservoir for the unit (60 W × 30 D × 60 H cm)
When another option is needed
- For tanks under 5 m³ or sites with no space around the tank, the submersible type (Pongle S) placed inside the tank
- For sites that irrigate directly from piping without a storage tank, an HQN configuration connected directly to the piping
- For tanks over 10 m³, contact us with the capacity
External circulation linked to existing irrigation equipment
A nanobubble circulation line is set up outside the storage tank while keeping the existing irrigation pump and nutrient supply equipment.

| Crop | Result (vs. control) | Period | Evidence |
|---|---|---|---|
| 5 pepper varieties | 14–58% higher yield | 2017.05–2017.07 | Cultivation test · Measured |
| Fruit vegetables | 7–38% higher yield | 2017.05–2017.07 | Cultivation test · Measured |
| Strawberry (about 3,300 m²) | 15%+ higher yield, larger share of top-grade fruit | 2018.09–2019.04 | On-farm trial · Measured |
| Oriental melon (early growth) | About 3× root density | 2 weeks after transplanting | Cultivation test · Observed |
Results vary with crop, environment and cultivation method. Cultivation tests were carried out with early prototype equipment; sugar content and firmness are based on farmer experience and published research.
Dissolved oxygen supply performance

| Category | Dissolved oxygen | Notes |
|---|---|---|
| Ordinary groundwater | 7–8 mg/L | Raw water |
| Cultivation test conditions | 15–20 mg/L | Pepper and fruit-vegetable tests |
| HEN-010 single pass | About 30–35 mg/L (+25–30 mg/L over raw water) |
In-house test · Measured |
| HQN-010 single pass | About 35–40 mg/L (+30–35 mg/L over raw water) |
In-house test · Measured |
A single pass is the value after water passes through the unit once. By adjusting operating time, the increase over raw water can be set within 10–40 mg/L for HEN-010 and 10–50 mg/L for HQN-010.
External circulation system linked to existing irrigation equipment
The nanobubble system is installed outside the nutrient tank or raw water reservoir and repeatedly treats the stored water through circulation piping to raise dissolved oxygen. The oxygen nanobubble water is delivered to the growing area through the existing irrigation pump and nutrient supply equipment.

-
Oxygen supply
Oxygen produced by the oxygen generator is supplied to the nanobubble module.
-
Nanobubble circulation
Water from the storage tank is pumped through the bubble mixer, where oxygen is dissolved, and the treated water returns to the tank.

Linked to existing irrigation
The oxygen nanobubble water is delivered to the growing area through the existing irrigation pump and nutrient supply equipment.

Pongle L FAQ
Answers to key technical and adoption questions when considering Pongle L.
Should I choose the surface-pump type or the submersible type?
If the unit cannot be placed inside the tank, the surface-pump type is the right choice.
The surface-pump type sits on the ground beside the tank and is connected by piping, so space outside the reservoir is needed. For tanks under 5 m³ or sites without space for the unit, consider the submersible type.
What is the difference between HEN-010 and HQN-010?
They differ in bubble type, operating pressure and power supply.
HEN-010 runs on 220 V single-phase at 2.5–2.8 bar and produces both nanobubbles and microbubbles; HQN-010 runs on 380 V three-phase at 4.0–4.5 bar and produces nanobubbles. Treatment flow (10 m³/h), size and oxygen generator (8 L/min) are the same.
Do I need to provide oxygen separately?
An oxygen generator is supplied with the unit.
No separate gas source such as oxygen cylinders is needed. You only need space beside the unit for the oxygen generator (60 W × 40 D cm).
How many hours a day should it run?
Operating time is adjusted to the target dissolved oxygen.
The required run time depends on tank capacity, irrigation volume per cycle and irrigation interval; we advise on operating time for your site conditions at the quotation stage.
Do I need to change my existing nutrient supply or irrigation equipment?
In most cases, existing equipment stays as it is.
The unit is connected to the tank by separate piping and circulates the water, so the irrigation lines are not changed. Space for the unit and power (220 V single-phase for HEN-010, 380 V three-phase for HQN-010) are checked before installation.
Which crops can it be used for?
Tests and trials have been carried out on peppers, fruit vegetables, strawberries, roses and other crops.
Results vary with crop and growing conditions; test conditions and results by crop are available in the case studies.
How do I check the price?
The model depends on tank capacity and irrigation conditions, so pricing is provided by quotation.
We propose a model and supply specification based on your crop, storage tank capacity and irrigation conditions.
How are installation and after-sales service handled?
Delivery and installation take about 2–3 weeks after ordering, and the warranty period is 1 year.
Failures caused by user error are repaired at cost; service requests are accepted via the inquiry form or by phone.
