HydroChill® Explained: How Shawgrass Fights Summer Heat

A recurring question from customers when looking into turf systems: "Doesn't it get really hot in the sun?"

That's a valid concern. Standard synthetic turf absorbs heat during peak sunlight hours and can exceed natural grass temperatures — warm enough to limit comfort for children and pets. For years, this was accepted as a trade-off.

HydroChill® reshapes that equation.

What HydroChill® Actually Is

HydroChill is a patented cooling technology developed by Shawgrass that works within the turf infill system. It is a safe and odorless antimicrobial agent that becomes gel-like upon water absorption. This gel is integrated into the sand layer under the turf surface, where it functions whenever the surface warms.

The mechanism is one you already know — evaporative cooling. It works the same way perspiration cools the human body. As heat builds, HydroChill releases moisture through controlled evaporation. This process reduces surface heat buildup, bringing temperatures down to a comfortable level for walking, sitting, and playing.

One key detail: HydroChill® increases performance in hotter conditions. The warmer it gets, the more active the cooling effect becomes. That means it works hardest when temperatures are highest.

How Much of a Difference Does It Make?

Testing by Shaw’s R&D team shows HydroChill®-treated turf can run up to 50 degrees cooler than conventional artificial grass under the same conditions. This is a substantial improvement — the difference between unusable midday heat and comfortable all-day usability.

HydroChill® performs best when the sun is at its highest point, when turf absorbs the most heat. Surface temperature depends on more than air temperature alone — sun angle, wind, shade, and cloud cover all play a role, so real-world results may vary. Still, the difference between treated and untreated turf remains consistently significant.

Common Questions About HydroChill®

How does it recharge?

It recharges naturally. Rainfall, dew, and irrigation all replenish it. Once hydrated, it can provide cooling for several days depending on weather. No special equipment is required.

Is it safe?

Yes. HydroChill® is a safe, non-toxic material. It is also antimicrobial, making it safe for children and pets.

Does it change turf appearance?

No. It is installed in the underlying infill system, so the turf maintains the same appearance and feel.

How long does it last?

HydroChill® is designed as a durable turf system component, not a temporary treatment. It is engineered to last alongside the turf installation, without frequent maintenance or reapplication.

Is it available everywhere?

It is available on selected Shawgrass product lines. The best way to confirm availability is to consult the Shawgrass team.

Who Should Consider HydroChill®?

HydroChill® is not limited to extreme use cases. It is a smart option for broad usage scenarios:

• Families with children who want unrestricted summer backyard play
• Pet owners whose dogs spend long periods on turf
• Schools and childcare facilities with regular recess and outdoor turf activity
• Commercial properties where outdoor comfort is expected consistently across the day
• Sports and training environments where heat influences performance

A Smarter Way to Think About Turf Heat

Heat used to be a major limitation for synthetic turf in hot climates. HydroChill® targets this limitation head-on, performing best when temperatures are highest and requiring no complex maintenance.

If heat concerns have held you back from artificial grass, this changes the equation.
