Rotor Air Coolers (RAC)

The Balcke-Dürr Rotor Air Cooler is an advanced design and solves the stress corrosion problem faced by many gas turbine applications. The innovative, patent-pending design is based on stress corrosion resistant material, the elimination of the expansion joint, and heat protection of critical parts. This protects the cooler against excessive fatigue from thermal cycling and increases its availability.

– Stress corrosion resistant material and design
– Critical parts are specifically designed to eliminate stress
– Failure Free Equipment: No unscheduled maintenance, reduced risk of gas turbine damage and higher availability of the plant
– Straight tube design fits into existing plants and allows simple retrofitting
– Alternative header type design available, enabling the highest thermoelasticity

Benefits

• Replacing existing RACs by maintaining the main connections
• Individual and customized solutions
• Increasing the plant’s availability and performance
