Zephyr Airdolphin Pro 48 VDC 1000-watt charger

Swing rudder

The rudder of the Airdolphin uses the Swing Rudder System, an attitude control system inspired by fish fin. The system can instantly respond to wind direction changes and achieve a more efficient power generation.

Rotor

The rotor system on the Airdolphin flexibly responds to various wind conditions from the slightest to the strongest, offering efficient power generation. It also frees you from pitch controls.

Innovation for Low Noise

The Airdolphin comes with the "Silent Disrupter Blade". This new blade has a number of thin grooves on its surface, which significantly reduces air flow noise. Our designers were inspired by the wings of owls that enables it to fly silently and unnoticed while approaching its prey.

Robust Body Structure

The robust body construction features a "no screw" assembly, inspired by Japanese traditional craft of "Block Puzzle". This construction ensures superb resistance to climatic conditions.

Power-Assist Function

When there is no wind, the Airdolphin uses previously generated power to rotate for 10 seconds per minute.
This will enable the rotor to start up at a mere 1.5m/s wind, reaching the cut-in point more efficiently. At the same time, the function prevents freezing in cold weather.

Power Generator

A power generator weighing 7.5kg and a maximum 4.5kW power output is used for the Airdolphin, realizing increased power generation and strong regenerating brake performance. The most powerful neodymium iron boron magnet called "NEOMAX" is used.

Data Communication System

The Zephyr Communication System allows you to connect the Airdolphin to the internet. You can also install an optional GPS receiver to the turbine for confirming each unit's location.

Unique Design - Winner of the Good Design Award 2005

Our original body-design with sleek lines and functional beauty was inspired by wild creatures of nature. Airdolphin's form represents harmony with the environment as well as the strong presence of the unit itself. As the name implies, our turbine looks alive, eager and ready to catch the wind.

Lifecycle Assessment

The CO2 emission during Airdolphin's production is roughly 180kg. It only takes 4 to 5 months to offset this amount through power generation by the wind turbine (avg. wind speed 4.5m/s, based on 0.425kg - CO2/kwh). Beyond this offsetting point, the amount of generated power becomes the amount of reduced CO2; thus contributing to the global environment (from Tokyo University Hirao laboratory's research data).

Power Management System

Zephyr's exclusive Power Management System is aimed at optimizing the safety and efficiency of power generation.

Non-Stop Operation / Continuous Output
The Airdolphin will generate at wind speeds of 2.5m/s through 50m/s.
It has a capacity of over 3kW output at strong winds of 20m/s or more.
However, when the conditions become too violent, it will switch to stall or soft mode (moderated spinning speed), continuing to work at reduced output up until wind speeds of 50m/s, at which point the turbine will finally stop, or will go back to normal mode once winds have stabled.

Safety Control
We applied several technologies to keep the turbine from disintegrating and allow it to control its output, even during overheating of the power generator, excessive spinning speed, and other negative situations.

High-Efficiency Operation
To maintain optimum efficiency at a variety of wind speeds, the turbine is controlled by a special computer program coordinated with the Multi-Stagger System of the rotor. We also developed a power management system which coordinates the special propeller design optimized for varying wind speeds and the power generator with superior efficiency.

Battery Charge Management
Management of the rechargeable battery, optimized for using the wind turbine as an independent power supply, is controlled by a system based on a 3-step battery recharge. Charge can be managed under a variety of conditions, from arctic to tropical weather. Management includes compensations for wire cable length, temperature, and even high currents of over 100 amps.
