• CSG-2 series available with an integrated refrigerated dryer (T models)
• All models available with i.HOC® integrated heat of compression dryer

Your advantages

• Heat-recovery made easy:
  Thanks to radial fans with high residual thrust, the heated exhaust air can easily be ducted away and used for heating an adjacent room without additional auxiliary fans.
• Energy-efficient features:
  In standby mode, the temperature-controlled Kaeser standstill fan reliably dissipates residual heat. This allows the main fan to turn off and cools the package down for quicker service.
• Exceptionally maintenance-friendly:
  Swing-out coolers make cleaning easy.
