ROTARY SCREW COMPRESSORS/With 1:1 Direct Drive
Download PDFBSD – Setting the standard
KAESER Compressors N pushes the boundaries of compressed air effi ciency once again with its latest generation of CSD and CSDX series rotary screw compressors. The value-added user benefi ts are immediately apparent just by taking a quick glance at the the completely redesigned compressor enclosure.
CSD/CSDX – Quadruple savings
These versatile rotary screw compressor ranges provide signifi cant energy savings in four ways: Firstly, low speed SIGMA PROFILE airends equipped with fl ow-optimised rotors have enabled specifi c power to be reduced by up to six percent compared with previous models. Secondly, the use of IE3 drive motors maximises energy effi ciency (use of these motors became mandatory in the EU from the 1st of January 2015). Thirdly, KAESER’s 1:1 drive design eliminates the transmission losses associated with gear or V-belt driven systems, as the motor directly drives the airend. Fourthly, the SIGMA CONTROL 2 compressor controller enables compressor performance to be precisely matched to actual air demand thereby allowing additional energy savings.
Perfect partners
CSD and CSDX series rotary screw compressors are the perfect choice for high effi ciency compressed air systems in industrial settings. The internal SIGMA CONTROL 2 compressor controller offers numerous 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 set-up 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 are directly accessible from the front of the unit.
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 Thermal 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 enhances energy effi ciency. This system also enables end users to better adapt heat recovery systems to suit their specifi c needs.
