Industries & applications
- Rooftop & overhead water tanks — pump-up control, overflow and dry-run protection for plastic, stainless-steel and underground storage tanks.
- Transfer, bore & submersible pumps — automatic start/stop on 220 V single-phase pumps and level inputs for 380 V three-phase control panels.
- Monsoon drainage & sump pits — pump-down and independent high-level alarm floats for basements, car parks, yards and flood-prone areas.
- Wastewater & septic systems — IP68 floats for sewage, greywater and pump-out chambers on residential and industrial projects.
- Aquaculture & agriculture — pond level control, irrigation reservoirs and livestock water supply across the Mekong Delta and Central Highlands.
- Fire tanks & industrial panels — level inputs for tủ điện điều khiển and packaged pump stations built for local contractors.
Why Vietnamese buyers choose ELEHPD
- A component supplier, not a retail competitor. Vietnam already has established local float-switch brands. Our role is to supply the sealed float element, cable and documentation to the OEMs, panel builders and brand owners who assemble or badge the finished product.
- Matched to 220 V / 50 Hz. Rated 250 V AC with 380 V maximum isolation, in 16 A (8 A), 10 A (8 A) or 10 A (4 A) versions — switching the contactor coil rather than the motor directly.
- Built for heat, humidity and immersion. IP68CS sealed body, rated 0–70 °C, PVC or HO7RN-F cable resistant to wastewater and oil.
- Verifiable endurance data. Over 100,000 mechanical and 50,000 electrical switching cycles — worth checking against the low cycle counts quoted on typical domestic-grade alternatives for commercial and project work.
- OEM / ODM private label. Custom cable lengths (2 / 3 / 5 / 10 / 15 m), float shapes and body colours, markings and packaging so Vietnamese brands can badge the range.
- Project documentation. English datasheets and wiring diagrams, with CE / RoHS under an ISO 9001 quality system; Vietnamese labelling and the technical file can be coordinated with the importer for CO/CQ and project acceptance.
Compliance note: whether a finished assembly falls under Vietnam's mandatory CR certification (QCVN / TCVN) depends on its HS code and the applicable regulation, and must be confirmed by the Vietnamese importer or panel builder. ELEHPD does not claim a Vietnamese CR certificate. Standard models are not Ex / intrinsically safe. We do not maintain a local repair centre or spare-parts warehouse in Vietnam — spares and documentation ship factory-direct.
Recommended products for Vietnamese systems
Field-proven level switches — each available in several cable lengths (2 / 3 / 5 / 10 / 15 m; custom on request).
- UKY & CX-M15 cable float switches — the 3-core (black / blue / brown) float for rooftop tanks, transfer pumps and sumps; one float does pump-up and pump-down by reversing two cores.
- UK ball float level controllers — compact spherical bodies for smaller tanks and tight chambers, 2 / 3 / 5 m cable.
- UK61 magnetic & UK71 / GSK dry-reed controllers — narrow wells and multi-point level control where a swinging float will not fit.
- CX-70AB / CX-80AB flow switches — flow monitoring and no-flow protection on booster sets.
Frequently asked questions
Do ELEHPD float switches work on Vietnam's 220 V / 50 Hz supply?
Yes. The cable float range is rated 250 V AC with 380 V maximum isolation (120 V AC versions for 110/120 V markets), in 16 A (8 A), 10 A (8 A) or 10 A (4 A) versions. That covers Vietnam's 220 V / 50 Hz single-phase supply. On 380 V three-phase systems the float switches the contactor coil inside the control panel, not the motor directly.
Do the switches carry a Vietnamese CR mark?
The float switch is a control component, not a finished appliance. Whether a given assembly falls under Vietnam's mandatory CR certification (QCVN / TCVN, administered by MOST / STAMEQ) depends on the HS code, the applicable regulation and the finished product; this must be confirmed by the Vietnamese importer or the panel builder for the complete assembly. ELEHPD does not claim to hold a Vietnamese CR certificate. We supply CE and RoHS documentation under an ISO 9001 quality system, plus datasheets, wiring diagrams and the technical files needed by the importer for its conformity assessment.
Which float switch suits a rooftop or overhead water tank?
A 3-core cable float (UKY or CX-M15) with black / blue / brown conductors. The same float can be wired for pump-up (fill a tank and stop at high level) or pump-down (empty a pit and stop at low level) by reversing two cores. Cable lengths of 2 / 3 / 5 / 10 / 15 m cover most tank heights; the switching level is adjusted by sliding the counterweight along the cable, with no tools.
Will they survive monsoon drainage, sewage and aquaculture duty?
The sealed polypropylene body is rated IP68CS for permanent immersion, 0-70 C rated operating range, with PVC or HO7RN-F cable resistant to wastewater and oil. Mechanical endurance is over 100,000 cycles and electrical endurance over 50,000 cycles. They suit clean water, wastewater, mild acid/alkali and light industrial duty. Standard models are not Ex / intrinsically safe, and highly viscous or heavily solids-laden media need a separate assessment.
Do you supply OEM and private-label programs for Vietnamese brands?
Yes. ELEHPD supplies factory-direct to Vietnamese OEMs, pump packagers, panel builders and distributors, with private-label markings and packaging, custom cable lengths, selected float body colours and shapes, and English datasheets (Vietnamese labelling can be coordinated with the importer). Spares and documentation ship from the factory; we do not maintain a local repair centre or spare-parts warehouse in Vietnam.
