The dry cooling systems for power plants have gained an increasing interest as an alternative to the wet cooling systems. They are likely to be preferred in the following circumstances:
- Early permission to build a power plant is usually in favor of the Dry cooling for which locations are in greater numbers and permits received earlier
- Water supply is an issue whether water is not/poorly available or made too expensive or a sensitive subject today or tomorrow
- The plume of the wet towers even reduced by use of a hybrid wet cooling tower is not welcome for various reasons.
