HV-TURBO centrifugal turbo compressors and aeration blowers

HV-TURBO engineering heritage and Howden turbomachinery manufacturing

HV-TURBO originated in Elsinore, Denmark, building decades of engineering expertise in single-stage integrally geared centrifugal turbo compressors.

Following its integration into Howden, the brand became the cornerstone of high-performance compression solutions advanced globally within Chart Industries and Baker Hughes.

Manufacturing facilities feature high-precision machining centers, impeller balancing bays, and advanced aerodynamic testing loops.

Machinery complies with API 672, API 614, and ISO 9001 standards, providing continuous, reliable air and process gas movement across municipal wastewater, chemical synthesis, and mining plants.

KA series single-stage compressors and integral gear transmission

KA series compressors integrate a speed-increasing transmission and aerodynamic volute onto a unified structural foundation skid.

The high-speed open-profile impeller mounts directly onto the pinion shaft, eliminating intermediate flexible couplings and reducing machinery footprint compared with multi-stage blowers.

The integral gearbox houses precision profile-ground gear wheels treated with thermochemical hardening for durability. Rotor rotation is supported by multi-pad hydrodynamic tilt-pad journal bearings, minimizing frictional power loss and ensuring long operating life under round-the-clock plant loads.

Dual Point Control™ flow modulation with IGV and VDV mechanisms

The proprietary Dual Point Control™ system combines variable inlet guide vanes (IGV) and adjustable radial diffuser vanes (VDV) driven by independent electromechanical actuators.

Coordinated vane positioning tailors internal aerodynamics to instantaneous plant demand, maintaining constant discharge pressure.

The inlet apparatus imparts pre-whirl to incoming flow, reducing motor power draw, while the variable diffuser prevents flow separation during turndown down to forty percent of rated capacity.

The mechanism compensates for seasonal ambient air temperature variations, sustaining high polytropic efficiency.

Energy-efficient biological aeration and oil-free air delivery

Aeration basins represent up to seventy percent of total electrical consumption at municipal and industrial wastewater facilities. HV-TURBO compressors deliver completely oil-free compressed air, eliminating lubricant contamination of biological sludge and preventing aeration diffuser pore fouling.

High operational stability and smooth throttling capability enable automated plant networks to meter dissolved oxygen dynamically against diurnal influent variations. This optimizes biological nutrient removal while delivering up to thirty-five percent electrical power savings.

Dynamic rotor balancing and Howden Uptime digital monitoring

HV-TURBO impellers are milled from solid forged high-strength aluminum alloy or stainless steel billets using five-axis machining centers.

Every rotor assembly undergoes high-speed multi-plane dynamic balancing on diagnostic test stands to eliminate residual vibration and secure smooth shaft operation.

Integrated Howden Uptime telemetry and API 670 vibration sensors monitor shaft displacement and journal bearing temperatures continuously. Digital monitoring identifies early mechanical wear patterns, enabling scheduled preventative maintenance without unexpected plant shutdowns.

Standardized spare parts selection via machinery nameplate data

Precise selection of replacement impellers, gear sets, hydrodynamic bearings, labyrinth shaft seals, and oil filtration elements requires the serial number from the compressor metal nameplate. This identifier enables engineers to retrieve original manufacturing data sheets and drawings.

Archival factory records pinpoint part numbers for labyrinth seal rings, bearing shells, oil pump gears, and vane actuators. All replacement components undergo dimensional quality audits and include technical documentation for plant maintenance teams.
