Magnetic bearing turbo blowers 200 and 400 hp


Turbo blowers for aeration applications

Are you looking for a reliable and energy-efficient supply of compressed air in the low pressure range? 

PillAerator turbo blowers from Kaeser Kompressoren are compact turbo compressors developed specifically with aeration applications in mind. Thanks to innovative magnetic bearings, the drive motor operates completely wear-free. 

Our turbo blowers are used wherever process air is required in the low pressure range – such as aerobic, biological wastewater treatment, fermentation and flotation applications.

Performance data:

  • 200 hp and 400 hp
  • Flow rate up to 9420 cfm
  • 4 to 20 psi

Your benefits:

  • High energy efficiency 
    The direct-drive, magnetic bearing rotor, coupled with an intelligent controller, ensures that PillAerator turbo blowers operate remarkably efficiently. Operating at exceptional levels of efficiency, these state-of-the-art machines can save up to 25% of the energy costs associated with conventional technologies.
  • Dependable and safe 
    A comprehensive range of sensors monitor the most important operating states such as pressure, speed and temperature. This ensures safe operation whilst guaranteeing a dependable supply of process air.
  • Maintenance-free drive motor
    Contact-free magnetic bearings that require no lubrication guarantee a completely wear-free operation. As no oil and bearing changes are required, maintenance is restricted simply to replacing the air filters.

Turbo blowers with wear-free drive motor

The benefits of using magnetic bearings are clear to see:


  • Oil-free
  • Wear-free
  • Maintenance-free

The shaft rotates permanently around its center of gravity, making it vibration-free. As it remains free from any physical contact, no lubrication is required.

Even frequent start-stop processes are completely wear-free. During shutdown, the shaft is brought to a standstill within the magnetic field. In the unlikely event of a failure of the magnetic bearing controller, the safety bearings will bring the shaft gently to a halt.

The drive motor is airtight, so it cannot be contaminated by the ambient air – substantially increasing the turbo blower’s operational reliability, availability and service life.

 

Product details

Innovative cooling concept
Innovative cooling concept in Kaeser turbo blowers.
  1. Magnetic bearing motor and frequency converter are both water-cooled
  2. Adjustable air/water heat exchanger
  3. Durable water/water heat exchanger
  1. Maintenance-free circulation pump
  2. Cooling water inlet and outlet available with heat recovery

Cooling takes place via an internal water circuit, so as to ensure operating conditions are consistently optimized. In addition to achieving constant temperatures for the motor and frequency converter via its speed-controlled fan, this allows the control cabinet to remain hermetically sealed.

Accumulated exhaust heat can all be absorbed by the cooling water, thereby rendering expensive exhaust air ducting superfluous. The optional climate control guarantees safe operation of the turbo in ambient temperatures as high as +130 °F.

Perfectly-matched flow rate

Infinitely variable speed control allows the flow rate of the turbo blower to be adjusted constantly in line with the current air demand of the application at hand. Not only does this allow the process to operate seamlessly, but it also reliably prevents energy losses due to over-aeration. 

Perfect interplay between the individual components, including the intelligent controller, allow efficiency rates of up to 80% and energy savings up to 25%.

Reliable and safe

PillAerator turbo blowers are delivered as complete machines, ready for connection, with perfectly matched mechanical and electrical components.

A range of sensors continuously monitor pressure, temperature and speed so as to ensure reliable operation of the blower and to allow remote monitoring and visualization of the operating status. 

A sophisticated safety design guarantees a gentle, wear-free shutdown in the event of a power failure, whereby the magnetic bearings remain active and fully functional.
