Compressor-free cooling
The FREETECH is an adiabatic (wet-dry) cooler that operates without a compressor. In normal operation it functions as an air-side heat exchanger (dry cooler), but in warm weather the evaporative (adiabatic) panels are activated: a misting system mounted in front of the heat-exchanger surface sprays a fine water mist that cools the incoming air.
Importantly, the spray water does NOT come into contact with the heat-exchanger surface, so the risk of scaling and corrosion is minimal. Closed-loop system = no Legionella risk!
Fields of application
- Industrial oil cooling (where 25–35 °C is sufficient)
- Replacement of cooling towers with a closed-loop system
- F-gas-free and energy-efficient solutions
- Supplementary cooling in summer
