System automates fans

MacroAir Technologies Inc.'s AirEffect is a climate-control system for high-volume, low-speed (HVLS) fans. With it, fan speeds and directions do not need to be constantly monitored and adjusted to respond to temperature fluctuations. AirEffect is designed to run fans at optimal speeds and directions based on temperature and humidity. It measures temperature and humidity at two points, calculates the heat index, and identifies the best operating speed and direction for each fan.
