Project Description

Flow rate 3.5 to 26.6 mÑ/min, Pressure 5.5 to 15 bar

For  optimum efficiency

KAESER KOMPRESSOREN pushes the boundaries of compressed air efficiency and availability once again with its latest generation of DSD series rotary screw compressors. Intelligent design solutions have not only lead to enhanced ease of operation and serviceability, but also give this series of class-defining compressors their distinctive modern appearance.

DSD – Energy savings as standard

Delivering improved specific power, the flow-optimised and further refined SIGMA PROFILE rotors provide the basis for exceptional energy efficiency. The use of high performance IE4 drive motors maximises energy efficiency, whilst KAESER’s 1:1 drive design eliminates the transmission losses associated with gear or V-belt driven systems, since the motor directly drives the airend. Furthermore, the radial fan fulfils the efficiency requirements for fans as per EU directive 327/2011. Last, but not least, the advanced SIGMA CONTROL 2 compressor controller achieves additional energy savings and minimises cost-intensive idling periods through the use of a variety of specially developed control options, e.g. Dynamic control.

Service-friendly = Efficient

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 efficiency: for example, all service and maintenance points are within easy reach and directly accessible from the front of the unit. This not only saves time and money, but also maximises compressed air system availability.

Perfect partners

DSD series rotary screw compressors are the perfect partners for high-efficiency industrial compressed air stations. The internal SIGMA CONTROL 2 compressor controller offers numerous communications interfaces (e.g.Ethernet), which, when connected within the KAESER SIGMA NETWORK, allows seamless communication with advanced master controllers, such as KAESER’s SIGMA AIR MANAGER 4.0, and in-house centralised control systems. This enables simple set-up and achieves unprecedented levels of efficiency.

Electronic Thermal Management

Powered via an electric motor, the sensor-controlled temperature control valve integrated into the cooling circuit is the heart of the innovative Electronic Therma Management (ETM) system. The new SIGMA CONTROL 2 compressor controller monitors intake and compressor temperature in order to prevent condensate formation, even under conditions with higher air humidity. ETM dynamically controls the fluid temperature and low fluid temperature enhances energy efficiency. DSD packages are equipped with a second ETM system if the heat recovery option is chosen. This enables heat recovery to be even better adapted to the customer’s exact requirements.

Why choose heat recovery?

The question should in fact be: Why not? Amazingly, up to 100 percent of the (electrical) energy input to a compressor is converted into heat. Up to 96 % of that energy can be reused for heating purposes. This not only reduces primary energy consumption, but also significantly improves the applicable company’s total energy balance.
