MacroAir Technologies' MacroVoltaic fan is a solar high-volume, low-speed industrial fan

MacroAir Technologies introduces the MacroVoltaic fan. Receiving the highest certified rating, the MacroVoltaic fan is the only solar high-volume, low-speed (HVLS) industrial fan on the market.

HVLS fan technology is designed to generate a column of air that flows down to the ground and outward 360°. This large, slow moving air mass moves throughout the space, mixing and circulating air more efficiently without generating the noise and dust created by other industrial fans. This movement of air not only offers cooling comfort in hot weather, but also provides comfort in cool weather, as well. Because a variance in temperatures often exists during winter months, MacroAir fans are designed to effectively combine elevated heat with cool air at the floor level. This de-stratification of the uneven temperatures at varying levels in a building provides a more comfortable, uniform temperature while saving money on heating costs.

The panels are sold in various wattages at an average cost of about $3.50 per watt. Because the HVLS fans only consume approximately 400 watts of power, smaller solar panels are able to power the MacroAir fans.

MacroVoltaic’s panels have a 20-year warranty and are rated for full sunlight. By using panels at wattages slightly higher than needed, the design ensures that the solar fan will function at full speed most of the time. The solar panels produce direct or DC current, which is a current flowing in only one direction. Most motors are operated using an AC current or a current that flows in both directions.

The MacroVoltaic air movement system includes the HVLS fan with an attached controller. The controller is a specialized component that converts the DC power from the solar panels into usable power for the fan motor. The motor and controller are designed to work together in a manner that is unlike traditional DC or AC motors. The MacroVoltaic system also includes the solar panels, standard remote control, an optional auxiliary power supply and an optional battery backup.

The MacroVoltaic is designed to operate in a variety of methods to best meet individualized consumer needs. The system can be used as a stand-alone solar fan, as a solar fan with auxiliary backup, as a solar fan with battery backup, or as a solar fan with both auxiliary and battery backup.

Used as a stand-alone solar fan, the MacroVoltaic system is well suited for consumers who want a completely solar air-cooling system. This method benefits consumers who are looking for energy alternatives, are unable to run traditional AC power sources to remote locations or are utilizing the fans primarily during daylight hours.  When used in conjunction with auxiliary backup, the MacroVoltaic fan can be used even when sunlight is not available to power the system. Although the optional battery backup does require some additional investment in the solar panels, the excess wattage produced is used to charge the batteries and store the energy for use at night or during cloudy weather.

When both the auxiliary and battery backup are utilized, the batteries are still charged through the solar panels. The auxiliary power ensures that there will always be a power source available to run the system.
