Rotor Air Coolers

Upgrade to Less Stress Corrosion Cracking

Stress Corrosion Cracking (SCC) in Rotor Air Coolers. A common failure in many combined cycle plants with 501 F and 501 G gas turbines. The new Balcke-Dürr  Rotor Air Cooler solves the stress corrosion problem faced by many 501F and 501G gas turbines.
The innovative, patent pending design, based on stress corrosion resistant material, eliminates the need for an expansion joint. The stress on the other critical parts is significantly reduced compared to conventional solutions. Additionally, parts are protected against excessive fatigue from thermal cycling. The selected materials and specially stress protected parts are designed to work hand in hand to increase the availability of your plant:

  • Stress corrosion resistant material and design
  • Critical parts are specially designed to eliminate stress
  • Low thermal stress
  • Fits into existing plant layout without any adjustments
