Turbine inlet cooling systems condition the incoming air to a lower temperature increasing air density and mass flow rate. The process restores the performance of the turbine to its peak capacity regardless of the weather. Leonardo DRS' Marlo Heat Transfer Solutions has successfully completed Turbine Inlet Coil project installations around the world.
Heating coils are used to improve the efficiency of the GT in turn down situations, or to reduce the possibility of icing in certain regions. Marlo has provided bare tube coils as well as standard fin and tube coils for heating installations improving the performance of the GT in such diverse applications.
Our standard Turbine Inlet Coils are approved by all major turbine manufacturers and all coils feature integrated lifting lugs and fully drainable circuits. Marlo offers optional corrosion preventative coatings, materials, and flexible duct mounting hole sizes and locations. Marlo can accommodate your unique requirements.
At Marlo Heat Transfer Solutions we work to achieve the best value solution for our customers. We have in-house resources to help you size the equipment to meet your cooling needs and minimize air pressure drop through the system. Improve turbine performance with a quality Marlo cooling coil, the most important part of your inlet system.

Advantages of Mechanical Turbine Inlet Cooling
Gas turbine mechnical cooling systems are used worldwide to improve power output. The power output of a gas turbine is inversely related to the inlet air temperature; as the inlet temperature increases the power output decreases. This characteristic creates less power thereby reducing output which in turn negatively affects the required performance. Turbine inlet cooling systems condition the incoming air to a lower temperature increasing air density and mass flow rate. The mechanical cooling process restores the performance of the turbine to its peak capacity regardless of the ambient temperature, humidity and availability of water.
Effects of Inlet Air Temperature on Gas Turbine Power Outlet
The extent of the benefits realized vary with location of the turbine due to differences in ambient air temperature from one climate to another. The implementation of mechanical turbine inlet cooling provides the following benefits to the plant owner for maximizing revenue opportunities:
Insure Your System Against Expensive Repairs and Lost Revenue
Icing is a condition that can negatively affect the performance and damage a gas turbine. In cooler climates humid air may cause ice formations. If carried into the gas turbine intake, ice crystals could damage the turbines blades, leading to extensive downtime and costly repairs.
Leonardo DRS' Marlo Heat Transfer Solutions has supplied heating coils for gas turbine inlet applications for many years. They have worked closely with many of the system suppliers as well as the OEM's to create coils that meet the demands of these difficult environments, while providing the heat necessary to eliminate the risk of ice formation. Marlo Heat Transfer Solutions coils provide value through cost savings, system protection and optimum performance while minimizing air pressure drop penalties on the system.
In addition to anti-icing coils, Marlo Heat Transfer Solutions heating coils are used to increase the temperature of incoming turbine air which in turn increases the efficiency of your gas turbine in turn down operation when full capacity of the turbine is not required. This has become more prevalent as more renewable energy sources such as wind and solar are brought online. This trend is expected to continue to expand.
Similarly to the cooling heat exchangers, the heating coils are manufactured to the strictest quality standards. Years of experience at Marlo Heat Transfer Solutions have provided a coil design that is simplistic in its implementation without sacrificing key performance characteristics.
Marlo Heat Transfer Solutions has been serving the industry's cooling and heating needs for turbines ranging in size from 20MW to over 500MW. They have performed under very extreme conditions demonstrating their performance, durability and reliability.
While the majority of their experience with turbine inlet cooling projects pertains to the cooling coils themselves, they can supply either the turbine inlet coils or consult on a complete turbine inlet cooling system. In either case, the company works to provide a total value solution for their customers. Through their extensive resources they are able to assist in sizing equipment, ensuring that cooling needs are met and the air pressure drop across the coils is minimized.
