Kaeser – Rotary screw compressors with 1:1 direct drive

Rotary screw compressors with 1:1 direct drivect

Energy-saving ideas in every component

You can meet virtually any compressed air demand with fluid-injected rotary screw compressors from Kaeser. We offer a huge selection of compressors ranging from 18.5 kW right up to 315 kW. All models are equipped with energy-saving 1:1 direct drive. The motor drives the airend directly without transmission loss via a maintenance-free coupling.

You can choose between the following models:

for integration in your compressed air station: our basic model
with refrigeration dryer for high compressed air quality: T versions (ASD, BSD, CSD, CSDX and DSD series)
with variable-speed drive for optimal efficiency and broad control range: SFC models
New: With synchronous reluctance motor: Significantly greater efficiency – especially in the partial load range – than comparable asynchronous systems enables considerable energy savings.
as complete solutions with integrated refrigeration dryer and variable-speed drive: T SFC versions (ASD, BSD, CSD, CSDX and DSD series)

Our fluid-injected rotary screw compressors are the perfect choice for industrial compressed air applications. We’d be glad to help you select the size and model that perfectly meets your requirements.

Your advantages

  • Exceptional efficiency:
    The use of IE3 motors has been mandatory in the EU since January 2015. Furthermore, we already use IE4 motors in our BSD – FSD models with 1:1 drive to provide you with even further energy savings.
  • Longer service life:
    Electronic thermal management dynamically controls the fluid temperature of ASD, BSD, CSD, CSDX, DSD, DSDX, ESD and FSD series compressors. This not only saves additional energy, but also reliably prevents condensate formation and associated moisture damage.
