for prime power or long-term continuous operation, especially in climates where its efficiency advantage is significant.
The Air Cooled Heat Exchanger (ACHE) remains the champion for standby, mobile, and smaller industrial Gensets due to its simplicity, reliability, and independence from water.
The choice ultimately boils down to a trade-off: Is the higher efficiency and power density of a cooling tower worth the increased cost, complexity, and maintenance? For most standard backup generator applications, the answer is no. For a large data center or industrial plant running on gensets for days or weeks, the answer is often yes.
