Southwest Greens Northern CA West is happy to deliver and install turf that saves San Francisco families and businesses money and time —allowing you to concentrate on the things that are most important. Using our modern HydroChill® cooling technology, we have taken on the summer heat in an intelligent and straightforward way. A basic add-on to the turf’s infill supplies a mean cooling range of 30-50 degrees and works automatically when wet by irrigation, rainfall, and dew.



Perspiration is a natural process of thermoregulation called evaporative cooling. Evaporation of condensation from the skin’s surface has a cooling effect. In the same way, HydroChill® has shown to cool synthetic green surfaces through the same process. As the turf surface is warmed by solar radiation, moisture stored in the HydroChill® turf is let off. Evaporating wetness removes heat, leaving behind a cooler, more comfortable green for the players.

  • HydroChill® uses moisture to produce a cooling effect. Rainfall, dew, and irrigation should help keep your lawn cool for days, depending on local weather.
  • HydroChill® can be incorporated into most of Southwest Greens' infilled lawn systems.
  • HydroChill® will not hinder the structural integrity or warranty of Southwest Greens’ products.
  • HydroChill® is UV-resistant and needs to be re-treated every two years for maximum efficiency.


Ambient temperature outside does not necessarily dictate surface temperature. The solar radiation time period, the angle of the sun, cloud cover, wind, and other elements all add to the temperature of the surface.

HydroChill® provides maximum benefit when the sun is closer to the Earth, as shown in the solar radiation calendar. During the summer in San Francisco, the sun sits overhead, causing surfaces to draw more heat, resulting in higher temperatures. The rotation of the Earth is likewise responsible for hourly variations in light therefore making HydroChill® most efficient during the hotter part of a clear day when needed most.
