Next Turbo Technologies

The product

PRODUCT

Next Turbo designs and produces robust and high efficient Integrally geared, single stage, centrifugal turbocompressors with variable diffuser vanes and/or inlet guide vane control.

Two frame families available:

Image description

The innovative GTB series

Integrated, compact and high-efficient

The GTB series features a compact design with reduced lubrication oil reservoir located in the gearbox, integrated oil distribution and hydrodynamic-housed hybrid ceramic bearings. Eliminating the pre-lubrication oil pump and the quantity of lubrication required during operation, the GTB achieves unparalleled low energy consumptions. This series is currently available for machines up to 500 kW drive power.

The core compressor can be shipped in a baseframe configuration with foot mounted electrcial drive motor or in a compact console configuration with flange mounted motor and self-aligning fexible coupling.

The traditional GTH series

Hydrodynamic bearing for large airflows

The GTH series features hydrodynamic tilting pad bearings for large airflows. Our current range extends up to 2,000 kW drive power - see more in portfolio overview below.

Due to the larger oil reservoir located inside the base and the required pre-lubrication pump this series is available only in the baseframe configuration.



All packaged in two distinct enclosure solutions:

Compact Plug & Play

With integrated softstarter, pre-cabled and tested

The GTB series, due to its compactness can be integrated into a fully enclosed, pre-cabled, pre-tested plug & play enclosure for immediate placement into the blower room. The package houses an integrated blow-off valve, Local control panel and even the motor control center (MCC) with softstarter, direct start or VFD starter..

A greatly reduced installation and commissioning effort. Reduces on-site works to a minimum.

Modular Enclosure Package

Customizable acoustic enclosure

The GTB and GTH series can be packaged into the modular acoustic enclosure. The enclosure is build around the machine on-site and can be adapted to the spedcifi requirements of the blower room and process piping. For example, the discharge direction can be adjusted in 15 degree intervals.

A versatile solution for all blower room conditions.

Variable diffuser vanes

For pressure constant, widest flow regulation

The variable diffuser vane (VDV) system regulates the airflow from <40-100% of design value with constant speed of the drive. The regulation is achieved without a pressure drop on the discharge.

Learn more in our explainer video: Diffuser control
Image description

Inlet Guide Vanes

For power optimization in fluctuating ambient conditions

The inlet guide vane (IGV) system pre-rotates the incoming air and adapts the compressor envelope to fluctuating ambinet conditions. Thus preventing drastically efficiency drop in off-design operation. In combination with the VDV system, our 2-point control can operate in the widest airflow range with optimal efficieny. The refined algorythm yields best-in-class results.

Custom milled impeller

The impeller shape that fits your location and process ... for improved efficiency

The impeller and impeller blade geometry is calculated individually for each project; adjusted in combination with the diffuser vane geometry. Variables that are consdiered in the customization are: ambient conditions (air temperature, humidity and barometric pressure) and air flow and pressure requirements. For an optimum compression of ambient air for your aeration or oxidation requirements.

Serviceability

Designed for reduced and ease of maintence

Next Turbo compressors are designed with an eye on maintainability and ease-of-maintenance. We are proud about the fact that life-prolonging service on-site can be done. The remainig lifetime can be estimated - no surprises with black-box components.

The design of the blower allows for the majority of maintenance tasks to be performed by plant personelle - after an initial training and if so wanted. Our local service centers and partners are of course avaialble for the task as well.
