BSD – Setting the standard

KAESER Compressors pushes the boundaries of compressed air effi ciency once again with its latest generation of BSD series rotary screw compressors. Not only do they deliver more compressed air for less power consumption, but they also combine ease of use and maintenance with exceptional versatility and environmentally responsible design
BSD – Multiple savings
The new BSD compressors save energy in multiple ways: The compressor airends are equipped with fl ow-optimised SIGMA PROFILE rotors and are controlled and monitored via the industrial PC-based SIGMA CONTROL 2 compressor controller. This enables free air delivery to be precisely matched to meet actual compressed air demand and ensures maximum energy effi ciency. Last, but not least, the use of Super Premium Effi ciency IE4 motors boosts energy effi ciency even further.
Perfect partners
BSD series rotary screw compressors are perfect partners for high effi ciency industrial compressed air systems. The internal SIGMA CONTROL 2 compressor controller offers multiple communication channels, which allows seamless communication with advanced master controllers, such as KAESER’s SIGMA AIR MANAGER, and in-house centralised control systems. This enables simple setup and achieves unprecedented levels of effi ciency.
Ease of maintenance ensures savings
The distinctive and eye-catching design of these systems from the outside is complemented by intelligent component layout on the inside for even greater energy effi ciency: All service and maintenance points are within easy reach and directly accessible. This saves both time and money when it comes to servicing.
Electronic Thermo Management (ETM)
Powered via an electric motor, the sensor-controlled temperature control valve integrated into the cooling circuit is the heart of the innovative Electronic Thermo Management (ETM) system. The new SIGMA CONTROL 2 compressor controller monitors intake and compressor temperature in order to prevent condensate formation, even with differing air humidity conditions. ETM dynamically controls the fl uid temperature – low fl uid temperature increases energy effi ciency. This system also enables the end user to better adapt heat recovery systems to suit his or her specifi c needs.
