Kaeser has launched its GBS sequence screw blowers for the ability vary from 75 to 160 kW. The blowers are characterised by a quantity movement of twenty-two to 104 m³/min and differential pressures of as much as 1100 mbar in addition to quiet operation, optimized house necessities and low upkeep.

The vary is designed to be as much as 35% extra environment friendly than conventional constructive displacement blowers and presents power benefits in comparison with many different screw blowers and centrifugal compressors available on the market. Its effectivity has been designed to stay fixed all through the management vary and never simply at particular factors, making the merchandise a viable different to turbo compressors.

Energy is transmitted from the engine to the compressor by way of a lossless and maintenance-free gearbox, which implies that the merchandise provide environment friendly operation and low upkeep. The merchandise are designed for space-saving set up and quiet operation.

Begin Managed (STC) variations can be found for mounted velocity operation. They’ve an built-in star-delta starter geared up with a premium contactor, an overcurrent relay and section monitoring. The STC variations even have an energy-saving IE4 Tremendous Premium Effectivity motor.

Sigma Frequency Management variations are additionally obtainable and have an built-in frequency converter to dynamically alter the movement charge to precise demand, with the frequency converter and motor being matched to attain continuously optimized general effectivity. Notably environment friendly synchronous reluctance motors are used for outputs of as much as 110 kW.

The facility consumption per movement unit (particular energy consumption in kW per m³/h) is ready in line with the tight tolerances of ISO 1217.

The built-in Sigma Management 2 ensures operational reliability and sensible communication by integration into course of management techniques, additionally with Business 4.0 necessities. The Sigma Air Supervisor 4.0 grasp management is really helpful for blower stations with a number of blowers, because it has management and regulation algorithms specifically developed for the wants of low-pressure purposes. This enables for even higher power financial savings and simplification of automation.

The blowers are appropriate for purposes with notably excessive power necessities – for instance for producing air for aeration in sewage remedy vegetation and bioreactors in addition to for flotation and fluidization.
