Market note · Vietnam
Dosing, acid correction and climate control for dragon fruit, durian, vegetables, cut flowers, pepper — built for 220 V / 50 Hz, single and three phase, shipped from Kunming.
| Power | 220 V / 50 Hz, single and three phase |
| Freight | Kunming → Hanoi by road, 2–3 days; sea via Hai Phong |
| Typical crops | Dragon fruit, durian, vegetables, cut flowers, pepper |
| Water | Surface and borehole water; alkalinity varies by province — dose acid where bicarbonate is high |
| Lead time | Standard models ex-works in 30 days |
220 V / 50 Hz means no re-rating: the units ship as built for our domestic fleet.
Kunming to Hanoi is a two-to-three day run, so a spare part is a courier away, not a container.
Where bicarbonate is high, the acid dosing loop holds pH instead of letting EC drift.

| INSFERT-ECO | Four-in-one entry unit for 5–20 ha blocks | US$3,430 |
| INSFERT-LITE | SS316 dosing, 10–50 m³/h, fits an existing headworks | US$4,050 |

Yes. ECO, LITE and mini ship in 220 V single phase; PRO and SP are three phase 380 V.
Standard models leave the factory in 30 days; road freight from Kunming to Hanoi is typically 2–3 days.
The app is English and Spanish today; labels on the cabinet can be supplied in Vietnamese for an order of five units or more.
A recent lab report: EC, pH, bicarbonate and hardness. We size the acid loop from those numbers.
