Cooling with Hydronics

  • Soil temperatures can be lowered by 12 -15°
  • Reduce heat stress to the rootzone by circulating cooling fluids through an underground network of tubing
  • Fluids absorb heat from the subsurface air, cooling the soil/sand to maintain a healthy rootzone 
  • In-ground sensors relay real time data of critical soil conditions to the Central Control
  • SubAir Hydronics response is automatic to eliminate adverse conditions
  • TurfWatch™ Technology allows remote access to all data, operations and equipment controls from any mobile device or computer console

Heating with Hydronics

  • Soil temperatures can be raised 18 -20°
  • In-ground sensors relay rootzone temperatures to monitor and activate the heating response of the system. 
  • With our TurfWatch™ Technology, continuous monitoring of conditions and immediate response can support turf health and a superior playing surface. 
  • Combining the use of hydronics with SubAir Systems, air pushed through the subsurface throughout the rootzone promotes the heat exchange in the rootzone to support root health and growth.

SubAir® Golf Hydronics, powered by industry-leading TurfWatch™ Technology, delivers precise heating and cooling to greens and practice tees, ensuring optimal turf health and playability year-round.

Hydronics Heating System
Keep your turf thriving even in freezing conditions:
• Raise soil temperatures by 23–28°F
Eliminate frost and reduce subsurface freezing
• Minimize risk of winterkill from sudden or prolonged cold snaps
• Extend seasonal play by maintaining rootzone warmth for active growth 

Hydronics Cooling System
Protect turf from heat stress and preserve surface performance:
• Lower soil temperatures by 15–20°F
Reduce root stress caused by prolonged high temperatures
• Maintain consistent playing surface quality even in peak summer heat

Integrated with SubAir® Systems
Paired with SubAir® Systems, air is actively circulated through the rootzone ensuring uniform treatment across the entire subsurface area. Whether you're facing scorching heat or deep freezes, SubAir® Hydronics offers the most effective solution for managing turf in extreme conditions.
