HST™ turbocompressors
Be quietly efficient
Time for change
Read on to see why it’s time to change.
HST™ turbocompressors
Innovative technology for incredible performance
Let’s get you up to speed
Magnetic personality
Rotor bearings controlled by magnetic fields mean high performance without mechanical friction. With no wear, why schedule downtime for bearing overhaul?
Never wearing thin
No mechanical wear maximizes service life and minimizes maintenance costs.
Stop start
Stop and start reliably without mechanical friction or wear - ideal for varying wastewater oxygen requirements.
Dry run
With no oil required for lubrication or cooling, don’t let leaking, frozen, boiling or sour liquid affect your uptime.

Labyrinth seal

1 The labyrinth seal is located behind the impeller and provides low leakage without mechanical friction or wear.
Touch down bearing

2 The touch down bearing catches and holds the rotor and acts as a back-up for the magnetic bearing system, protecting the rest of the high speed unit.
Position sensor D-end

3 The conical sensor determines the rotor position in three dimensions simultaneously and provides input to the separately mounted magnetic bearing controller.
Radial actuator

The controller sends appropriate currents to the two radial actuators (4) which contains four horseshoe magnets each. These work together to keep the rotor in the correct position.
Axial actuator

Position sensor N-end

HST™ turbocompressors
Turn down the volume at your facility
No more noisy neighbors
Quiet performance
In the past, blowers and excessive noise have always coexisted. Move away with the HST’s quiet high speed blower technology. Well thought out designs and simple measures such as noise insulation, facilitated by the turbo technology, mean no more eardrum shattering noises during operation. We’ll help you keep the volume down.




Turn it down
Multiple options and accessories such as unique silencers and customized ductwork can reduce noise beyond the blower. Select your options below to hear for yourself.
