NINGBO BLUETECH IMPORT & EXPORT CO., LTD.
Established in 2006 by an elite group of vertical transport specialists, NINGBO BLUETECH has accumulated nearly 20 years of professional industry experience. Headquartered in Ningbo, China, we have established a global footprint as a premier developer, manufacturer, and exporter of elevator systems, escalators, and key components.
Our comprehensive solutions span home elevators, passenger elevators, sightseeing elevators, freight elevators, and dumbwaiters. Guided by structural ingenuity and safety compliance, all our systems are engineered and produced under the latest EN-81 standard.
Over the decades, we have aggressively invested in R&D to solve structural and electrical constraints in residential projects. This dedicated pursuit of safety, architectural flexibility, and cost efficiency has earned our systems prominent distribution rights in more than 30 countries across Europe, the Middle East, Southeast Asia, and Africa.
In contemporary architectural engineering, the restriction of available power supplies poses a substantial challenge. Traditional passenger and freight elevators rely heavily on 380V–415V three-phase electrical connections. However, residential buildings, heritage restorations, and remote industrial setups frequently lack access to three-phase infrastructure. Retrofitting three-phase grid power to existing properties can cost tens of thousands of dollars in utility upgrades. This financial barrier has fueled the global market demand for single-phase 220V–240V vertical transportation solutions.
By leveraging single-phase 220V–240V power pipelines, real estate developers and residential homeowners completely bypass utility retrofitting costs. Our technology plugs directly into standard household outlets, saving thousands in infrastructure installation fees.
Machine Roomless (MRL) technology integrates the traction motor within the hoistway itself. By utilizing compact Permanent Magnet Synchronous Motors (PMSM), we reduce architectural overheads, maximizing space utilization inside the cabin.
Our Variable Voltage Variable Frequency (VVVF) control boards limit the starting current of the elevator to under 15A. This avoids household voltage dips, preventing light flickering while enabling silky-smooth acceleration and braking curves.
Single-phase traction systems require precise engineering due to the voltage constraints of a single line. Standard single-phase power is natively susceptible to starting torque limitations. To overcome this, Ningbo Bluetech integrates advanced vector-controlled VVVF inverters alongside high-efficiency PMSM gearless machines. This combination enables the lift to deliver 100% starting torque at zero speed, facilitating standard passenger loads up to 400kg on a 230V connection.
| Specification Parameter | Detailed Engineering Rating | Structural Benefit / Compliance |
|---|---|---|
| Input Power Supply | 220V / 230V / 240V AC Single Phase (50Hz / 60Hz) | Direct connection to domestic grids; no phase converter required. |
| Motor Power Rating | 1.1 kW – 2.2 kW (High Torque Gearless PMSM) | Matches power draw of a standard household air conditioner. |
| Starting Line Current | Less than 12A – 15A (Controlled Ramp-up) | Prevents voltage fluctuations and standard circuit breaker tripping. |
| Rated Payload Capacity | 250 kg / 320 kg / 400 kg | Optimized for 3 to 5 passengers, perfect for residential use. |
| Rated Speed Range | 0.3 m/s – 0.4 m/s (VVVF Controlled) | Offers comfortable acceleration without high mechanical stress. |
| Emergency Operation | Automatic Rescue Device (ARD) with UPS Backup | Safe passenger evacuation to the nearest floor during power failures. |
| Hoistway Pit Depth | Minimum 150mm – 300mm | Drastically simplifies architectural excavation requirements. |
| Overhead Clearance | Minimum 2800mm – 3000mm | Fits easily into standard residential ceiling heights. |
Elevator installation demands strict compliance with regional voltage grids and construction styles. A one-size-fits-all elevator will fail during foreign building inspections. We have customized our Single-Phase Elevator lines for localized application scenarios around the globe:
For the US and Canadian residential markets, our power supply modules are designed to integrate seamlessly with 120/240V split-phase wiring systems. This allows the elevator controller to draw power from the dual 120V lines, delivering a clean 240V to the VVVF inverter. This setup fully complies with ASME A17.1 home elevator codes, assuring rapid approval from local building inspectors.
European urban projects frequently involve retrofitting elevators into historical masonry shafts and heritage structures. Because building ordinances strictly prohibit significant structural alterations, our single-phase elevators feature low headroom requirements (as low as 2800mm) and ultra-shallow pit setups. The system is designed to plug directly into the standard European 230V single-phase grid under EN-81-41 norms.
In developing regions and remote environments across Latin America and Sub-Saharan Africa, grid reliability remains a primary challenge. Our single-phase systems can be integrated with battery storage networks and solar inverters. By drawing only 1.5kW during peak lifting loads, these lifts can run completely off-grid, using battery power recharged by local solar arrays.
For modern prefabricated and modular housing, we offer self-supporting structural aluminum shafts. These shafts bypass the need for concrete hoistway construction. Installers only need to secure the structural frame to the building slab, insert the cabin, and connect the single-phase power cord, shortening installation timelines to under three days.
Ningbo Bluetech operates at the center of China’s most advanced industrial manufacturing corridor. This strategic location gives us a unique competitive advantage in raw material procurement, technological development, and international shipping logistics.
We leverage automated fiber laser cutters and CNC hydraulic press brakes to guarantee sub-millimeter tolerances on all elevator cabins and guide rail brackets.
Our synchronized supply chain allows us to complete standard production within three weeks, and urgent custom orders in as little as two weeks.
Located near one of the world's largest deep-water ports, we optimize logistics to minimize ocean freight lead times and reduce inland transport fees.
Every single-phase traction machine undergoes dynamic brake testing and control panel thermal diagnostics before being packed for export.
Our track record of engineering excellence has earned us partnerships with tier-one international elevator corporations. We regularly collaborate with organizations like Mitsubishi Middle East and ThyssenKrupp Africa, serving as an OEM supplier for residential lift modules, modernization packages, and specialized single-phase components.
Whether for new construction or modernization projects, NINGBO BLUETECH is a trusted choice for vertical transport. With nearly two decades of industry experience, an unwavering focus on safety, and a dedication to sustainable design, we deliver tailored systems for global projects.
Vertical transportation is evolving to prioritize intelligent efficiency, predictive safety, and environmental integration.
Our R&D department is designing regenerative single-phase drives that harvest thermal energy during cabin braking. This energy is fed back into the home's micro-grid, reducing overall consumption by up to 30%.
Next-generation controllers will feature real-time IoT diagnostic boards. By tracking motor vibration, current draw, and cycle counts, the system alerts local maintenance teams before a component fails, minimizing downtime.
By incorporating carbon-fiber composites and high-strength aluminum alloys, we aim to reduce cab weights by 25%. This will allow higher passenger payloads on standard single-phase 220V residential grid connections.
