Power generation facilities including gas engine power plants, biogas plants, CHP cogeneration stations and backup generator parks require stable heat rejection for jacket water, HT‑LT cooling loops, lube oil circuits and transformer cooling systems. Dry coolers are widely deployed as an alternative to cooling towers, especially for remote power sites, water‑scarce areas and projects with strict wastewater discharge regulations.
Inside power generation systems, hot glycol‑water mixture carries waste heat from power‑generating equipment. The fluid flows to outdoor dry coolers. EC variable‑speed fans force ambient air across fin‑tube coils to discharge heat into the atmosphere. The cooled circulating fluid returns to engines, generators and auxiliary equipment to maintain safe operating temperature. Under normal dry operation, no process water evaporation occurs.
For regions with high summer ambient temperatures, optional adiabatic spray systems can be equipped to increase peak cooling capacity. In cold seasons, dry coolers can leverage low outdoor air to realize partial free‑cooling and reduce overall plant energy consumption.
‑ Water saving closed‑loop design: Minimizes makeup‑water demand, avoids blow‑down wastewater, chemical water treatment and legionella risks compared with open cooling towers. Perfect for off‑grid and remote power generation sites. ‑ System reliability for continuous power output: Supports glycol anti‑freeze solution for year‑round outdoor operation. Protects gas engines, biogas generators and transformers from overheating, helping extend equipment service life. ‑ Modular & redundant design: Units can be installed in parallel. Covers small backup generator sets up to multi‑megawatt power plant auxiliary cooling, supports N+1 redundancy for non‑stop power supply. ‑ Adapt to harsh site conditions: Hot‑dip galvanized frame plus multiple anti‑corrosion coil coating options for coastal, dusty or industrial corrosive atmosphere. ‑ Smart control integration: BMS communication available, fans auto‑adjust speed based on fluid temperature to optimize part‑load energy performance.
Typical application scenarios: gas engine power plant, biogas / landfill gas power station, CHP combined heat and power plant, diesel / gas backup generator park, transformer cooling for power substations, waste‑heat recovery ORC systems.
CST Heat Exchanger offers custom dry coolers for power generation industry. Horizontal, V‑type configurations, adiabatic spray kits and corrosion protection solutions are available for different power‑plant working conditions.
