Kaeser Compressors FSD.3 series rotary screw compressors

Tuesday, 09 May, 2017 | Supplied by: Kaeser Compressors Australia


Kaeser Compressors has announced the launch of its latest generation FSD series rotary screw compressors, enabling air cooling of rotary screw compressors for larger drive powers over 250 kW.

The radial fan in Kaeser’s cooling system draws in ambient air directly through the cooler without being pre-warmed to ensure optimum cooling performance. FSD compressors can therefore be used in ambient temperatures as high as 45°C. FSD models are also optionally available as water-cooled versions.

The radial fan is integrated into Kaeser’s Electronic Thermo Management (ETM) system, which regulates oil temperature to ensure a safe and consistent differential from the dewpoint temperature. With the heat recovery option, a second ETM system assures optimised and even more efficient usage of the available heat energy. This optimised efficiency results from the refined screw compressor blocks equipped with high efficiency and flow-optimised Sigma Profile rotors, achieving power savings of up to 15%.

The screw compressor block is directly driven by an energy-saving motor that operates at a low speed of 1490 rpm. Direct drive not only eliminates the transmission losses associated with gear drive, but also reduces energy consumption, maintenance requirement and sounds levels.

The unit’s environmentally friendly fluid filter cartridges no longer have a permanently attached sheet metal housing, but rather are simply inserted into an aluminium housing. The cartridges themselves feature a metal-free design and are suitable for thermal disposal at the end of their service life without additional pretreatment.

The rotary screw compressors are service friendly, with good accessibility to all maintenance components. The user-friendly Sigma Control 2 compressor controller provides additional energy savings, reduced maintenance requirements and compressor availability by dynamically adjusting the flow rate to match actual compressed air demand.

The large display makes it easy to view key information. Including RFID technology assures safety of data and login, meaning service work and system changes to the compressor can only be performed by authorised personnel.
