Evaporative cooling for reliable year long efficient cooling
About
Open Cooling Towers – also known as wet cooling towers – use the principle of water evaporation to efficiently cool process water. This proven cooling technology is ideal for industrial applications requiring high thermal capacity with minimal energy input.
Known across industries as wet cooling towers, cooling towers, tour de refroidissement, or Nasskühlturm, these systems remain a cornerstone of reliable heat rejection.
Applications & Benefits
Open Cooling Towers are widely used for:
- Cooling of industrial process streams
- HVAC systems in large buildings and facilities
- Recirculating cooling water in power generation
- Integration with heat recovery systems
- Efficient cooling during peak ambient temperatures
By evaporating a small portion of the water, these systems remove heat effectively while keeping operational energy use low – as long as water treatment is managed properly.

Key Features
- Open circuit evaporative cooling
- High thermal capacity with low power demand
- Requires careful management of Legionella risk
- Effective even in high wet bulb temperatures
- Modular and scalable for various industries
