1 Rotary Screw Compressors with the world renowned SIGMA PROFILE Equipment for marine Air deliveries from to m 3 /min Pressure 7.5 to bar

2 What qualities do users look for in a compressor? Normally, the answer would be efficiency and reliability. That may sound simple, but a lot of very different factors play an important part. Energy costs, for Compressor Investment Maintenance costs Potential energy savings Energy costs example, taken over the lifetime of a compressor, add up to a multiple of investment costs. This is why efficiency is vital in the production of compressed air. Another major factor is the reliability of air supplies in the quality and quantity needed. This is the most significant requirement for production plant that relies on compressed air. Reliability also means a supply of air of constant quality that increases the efficiency of air treatment equipment downstream of the compressor. Nonetheless important is the influence of minimum maintenance on the economical use of a compressor package. This is achieved with high-grade, durable components logically laid out to be easily accessible. KAESER s rotary screw compressors fulfil these requirements entirely, providing the basis for a highly efficiency, reliable and user-friendly air system. For all marine requirements in service air / control air, KAESER supplies solutions in compressed air which are dust, water, oil-free and if necessary sterile. 8 KAESER has the answer the SX, SM and SK series KAESER was one of the first compressor manufacturer to apply V-belt drive featuring an automatic tensioning device that ensures constant efficient power transmission, significantly reducing maintenance. Another advantage is the flexibility inherent in V-belt drive if, for example, a change in system pressure is required. The SX, SM and SK screw compressors are a consequent reaction to customers needs: economical power consumption, low noise emission, low servicing effort, maximum reliability and even better air quality. Many innovative solutions were needed involving overall cooling, soundproofing and the reduction of servicing requirements. The result is a mature and reliable product of recognised KAESER quality the SX, SM and SK series. 1 Inlet valve 2 Airend 3 Electric motor 4 Separator 5 Fluid cooler 6 Fluid filter 7 Separator cartridge 8 Minimum pressure/check valve 9 Aftercooler

3 SX, SM, SK Advantages constructed for ambient environment up to 46 degrees Compact reliability Because of their clever design, the SX, SM and SK series occupy minimal floor space. Even so, component accessability is superb, with wide-opening doors and large, removable panels greatly simplifying maintenance. High quality components and their careful layout contribute to the outstanding reliability of these compressor packages, giving you triple savings: firstly with efficient power transmission secondly with improved power consumption and thirdly with lowered servicing and related downtime costs. Optimum accessibility

4 Airend with SIGMA PROFILE The airend rotors feature the high-efficiency SIGMA PROFILE developed by KAESER. Accurate machining and heavy-duty precision bearings guarantee continuous performance and long life. Example 1: The most common component arrangement is compressor, air receiver, and desiccant dryer Power-saving electronic motor KAESER s high efficiency motors consume less power for more output. They are dust and splashproof to IP 54 and conform to insulation class F for more power reserve. Example 2: An arrangement used if demand fluctuates heavily is compressor, centrifugal separator, refrigeration dryer, and air receiver Automatic belt tensioning Correct belt tension is automatically assured, resulting in constant transmission efficiency, extended belt life and high reliability. Effective fluid separation The combination of centrifugal and gravitational initial separation with a special separator cartridge results in less than 2 mg of fluid remaining in each cubic metre of compressed air. Maintenance requirements are minimal. The easy-to-use control system SIGMA CONTROL is based on a robust, updateable industrial computer with a real time operating system. The operational state of the compressor is quickly ascertained with the help of traffic light coloured LEDs. A four-line, plain text display, easily understood icons and touch keys allow fast setting up and operation. SIGMA CONTROL regulates and monitors the compressor fully automatically. If an alarm occurs, the safety chain shuts down the compressor immediatelly. Cooling air filter mats Premature clogging of the fluid/air cooler is prevented by effective filtration of the ambient air drawn in for cooling. Dual, Quadro, Vario and continuous control modes are available. The most energy-efficient control mode can be selected depending on actual air needs. Interfaces to a modem or printer, to a second compressor working in sequence and to a data network (Profibus DP) are provided as standard.
