Sulzer Pumps Launches Its Next-Generation Turbocompressor

Sulzer Pumps has reinforced its leadership in turbocompressors for wastewater aeration with the launch of a new product called the ABS turbocompressor HST 20.With exceptional savings from wire to air, the new turbocompressor provides more air output for every kilowatt. And by integrating silencers and other accessories, it makes for a smaller, quieter, more cost-effective installation.

Advances Built on Proven Technology
Sulzer Pumps pioneered the use of direct-driven high-speed turbocompressors for wastewater aeration processes. The HST technology, which is 100% air-cooled, has been tried and tested in almost two decades of operation. With the ABS turbocompressor HST 20, its well-known strengths have been further developed.

Exceptional Savings From Wire to Air
The ABS turbocompressor HST 20 offers truly outstanding wire-to-air efficiency, which comes from optimizing the turbocompressor as a whole, rather than targeting individual components. A balance of features, including a high-speed permanent-magnet motor, a newly designed impeller and a new labyrinth seal design, yields the most air output for every kilowatt put in. This means considerable savings in an application that often represents more than 70% of a wastewater facility's energy use.

Stable Efficiency With Magnetic Bearings
Magnetic bearings allow the ABS turbocompressor HST 20 to operate in a safe and controlled manner with small impeller clearances. They run less risk of damage, pose no service difficulties and consistently safeguard operating efficiency.

Compact and Cost-Effective Installation
The ABS turbocompressor HST 20 is a completely integrated and practically noiseless package. The air-cooling system, outlet diffuser, silencers and more are all incorporated into the cabinet, which eliminates costly accessories and makes installation easy. Maintenance is limited to regular check-ups and an occasional change of the air filter, which is a huge contrast to the costly and extensive overhauls needed with screw compressors and positive displacement blowers.

Intuitive Control That Optimizes Your Process
The control system of the ABS turbocompressor HST 20 provides a clear overview and visualizes necessary actions on the touchscreen display. It also continuously records process data, which operators can use make proactive improvements that increase uptime and efficiency.
