Free Coolers | Free Cooling System

Transtherm Free Coolers are designed to reduce energy consumption and improve the carbon footprint of chilled water systems. When ambient air temperatures are low enough, through the majority of the autumn, winter and spring, the free cooler automatically dissipates the system heat allowing the more energy consuming chiller to switch off. 

  • Complete with integral controls, 3 way valve and actuator and bypass pipe work
  • Can be easily installed on existing systems as well as new builds
Transtherm’s adiabatic system provides “very effective management of Legionella risk”
