THE POWER GENERATION CHALLENGE

Power generation systems demand cooling solutions that prevent overheating, extend equipment life, and maintain efficiency under increasingly strict regulatory and cost pressures.

Stricter Emissions Standards.
Lower Cost per kWh.
Zero Tolerance for unplanned Downtime.
Overheating & Downtime Risk Icon 01
Overheating & Unplanned Downtime Risk
Leaking or undersized radiators, low coolant levels, and blocked airflow are common triggers of overheating events. A robust cooling circuit — radiator, pump, fan, thermostat, and hoses — must keep metal and lubricant temperatures within specification to prevent unplanned shutdowns.
Every degree over spec risks an unplanned shutdown
Operational Efficiency Icon 01
Operational Efficiency & Cost Control
Maintaining optimal coolant and metal temperatures improves thermal efficiency, enabling required kW output at the lowest fuel input cost. Efficient cooling systems support emissions reduction strategies while maintaining safe temperature margins.
Lower fuel input — lower cost per kWh
Lifecycle Reliability Icon

Frequently Asked Questions

Common questions about Power Generation heat transfer applications and API Heat Transfer solutions.

What heat exchanger solutions does API Heat Transfer provide for power generation?+
API Heat Transfer supplies heat exchangers for all aspects of power generation including turbine lube oil cooling, generator hydrogen cooling, steam condenser service, air intake cooling, fuel gas conditioning, and auxiliary cooling systems. Products span shell and tube (Basco®), plate (SIGMA®), and air cooled (AIRTECH®) technologies, engineered for continuous duty and high-reliability requirements.
Does API Heat Transfer supply turbine lube oil coolers?+
Yes. API Heat Transfer’s Basco® shell and tube heat exchangers are widely used as turbine lube oil coolers in gas turbine, steam turbine, and hydro applications. These are engineered for continuous duty, compact footprint, and easy in-service maintenance. TEMA and ASME certifications are standard. API has supplied turbine lube oil coolers to power plant OEMs and EPC contractors globally for over 150 years.
Can API Heat Transfer supply heat exchangers for hydrogen-cooled generators?+
Yes. API Heat Transfer supplies gas coolers for hydrogen-cooled generators used in large utility and industrial power generation. These are typically shell and tube designs engineered for hydrogen gas duty, with specific attention to materials compatibility, leak-tightness, and safe operation under ASME pressure vessel code requirements.
What role does a heat exchanger play in combined cycle power plants?+
In combined cycle gas turbine (CCGT) plants, heat exchangers are used throughout the plant for turbine inlet air cooling, compressor inter-cooling, lube oil cooling, steam condenser service, and heat recovery steam generator (HRSG) auxiliary systems. API Heat Transfer’s product range covers all of these duties and can be engineered to meet the tight space and reliability requirements of combined cycle installations.
Are API Heat Transfer heat exchangers suitable for renewable power generation?+
Yes. API Heat Transfer serves the alternative and renewable energy sector including biomass, geothermal, concentrating solar power (CSP), and hydrogen production applications.
