New fan options can be equipped with sensors that slow down or turn off the fan when golfers are present or natural wind is adequate.
Fans are valuable infrastructure for many golf courses because they make it possible to generate air movement on demand. While not a silver bullet, fans go a long way in helping superintendents manage the stress experienced by putting greens in challenging growing environments. If your course currently has fans that may need replacement, or if you’d like to invest in fans but have faced golfer resistance about issues like noise, you should look into some of the new options available.
Fans have a life cycle of eight to 10 years. More-frequent use and failing to keep up with routine maintenance can shorten a fan’s lifespan. With that in mind, fans should be routinely evaluated and serviced to extend their life and help you identify when a replacement plan needs to be put into action.
As with most technology, putting green fans have improved over the years. Some newer fans have integrated sensors that detect movement and monitor wind speed. The fan will slow down when golfers are nearby to be less disruptive. And if natural air movement is adequate, the fan will turn off to save energy. Once golfers leave or wind speed slows, the fan will resume normal operation to help regulate canopy temperature and minimize any residual moisture from dew or irrigation. Some newer models also use lightweight blades, an open-frame design, and direct-drive motors to move air more efficiently while reducing noise and energy use.
If you already have fans in place, fall is a good opportunity to evaluate where they are in their life cycle as they are taken out of service for the winter. Consider their age, condition and performance and whether newer technology could provide an upgrade. If you don’t have fans but feel like they would be beneficial, this is a good time to familiarize yourself with some of the new options that can help address golfer concerns about noise and disruption.
