What qualities do users look for in a compressor with variable frequency drive and a refrigeration dryer? Normally, the answer would be efficiency and reliability with compressed air of constant quality. That may sound simple, but a lot of very different factors play important parts. Energy costs, for example, taken over the lifetime of a system, add up to a multiple of investment costs. This is why efficiency is vital in the production of compressed air. ir system investment Maintenance costs Energy costs Potential energy savings T SF appropriately modular has the answer - flexible modular design SD, SD and SDX screw compressors can be combined with refrigeration dryer and/or SF variable frequency drive modules, allowing the most varied requirements of air quality and economy to be fulfilled. further advantage is the minimised installation work needed as the machines are prepared for immediate connection and operation. SD, SD and SDX an economical basis The new SD, SD and SDX series compressors with energy-saving : drive serve as the basis for the modular concept. They are particularly efficient, durable and reliable because of their generously-sized airends with SIGM PROFILE rotors turning at low speeds. T Refrigeration dryer SD, SD and SDX compressors can be supplied with an attached refrigeration dryer module as required. The compressor and dryer are accommodated in separate cabinets with individual apertures to increase operational reliability. Just as vital is the reliability of air supplies in the quality and quantity needed - these are the most significant requirements for production plant. 9 5 Sigma Frequency ontrol The SF variable frequency drive module is available for all compressors in the range. The SF module and the compressor form a compact, hard-wired unit with a small footprint and short communication paths between the control electronics and drive motor. The system is assembled, tested and ready to go. 5 9 Inlet valve Electric motor irend Fluid separator with cartridge Fluid cooler Fluid filter ompressed air aftercooler SF module ontroller with industrial computer Flexible, modular design The intelligent, modular concept of the T SF machines provides the right answer to every application.

SF consequent efficiency uilt for higher ambient temperatures The generously-sized SF module with its efficiently-cooled control cabinet allows trouble-free operation in ambient temperatures up to +5. Innovative: SD SF, SD SF and SDX SF series These rotary screw compressors with large, efficient airends, high performance SIGM PROFILE rotors and directly-coupled drives with no transmission losses are real energy savers. This applies particularly to variable speed machines equipped with SIGM FREQUENY ONTROL. Depending on the size of the compressor, power-savings of up to 50 percent can be achieved in larger air systems. No interference The electro-magnetic compatibility (EM) of the components and of the complete machine has been tested and certified. SD T SF front view Other variable speed compressors Transmission losses Power consumption Maintenance costs Uncompromising energy-savers SF compressors SD SF, SD SF and SDX SF machines from are economical rotary screw compressors with directly-coupled, variable frequency drives. Their large, slow-speed airends with energy-saving SIGM PROFILE rotors show outstanding performance data over the whole of the controlled speed range. Furthermore, these machines can run at full load over a 00 percent duty cycle with no increased service requirement. The directly-coupled drive functions without any of the transmission losses associated with geared drives. It has fewer components, a feature that brings improved reliability, extended operational life and reduced noise levels. The directly-coupled one-to-one drive brings triple savings: firstly with efficient power transmission, secondly with reduced power consumption and thirdly with lowered servicing and downtime costs.

Furthermore, the controlled acceleration and deceleration of moving parts reduces dynamic loading.
SD/SD/SDX T SF eight decisive advantages SIGM PROFILE IREND given power can be used to turn a small airend at high speed or a larger airend at slow speed. Larger, low speed airends are more efficient, delivering more compressed air for the same drive power. That is why developed airends especially for the SD, SD and SDX series that precisely match the individual drive power and motor speed of each machine in the range. The slightly higher cost of the larger airend is quickly recovered by the energy saved during operation. 5 n efficient condensate separator in stainless steel The separator tank in the refrigeration dryer is made completely of stainless steel and is non-corroding. deflector plate forces the compressed air streaming into the separator into cyclonic motion. Finally, the air flows through a stainless steel wire web that provides a very high degree of separation of 99.9 percent. This is almost constant, despite fluctuating airflow, reliably maintaining the dew point. Solid particles are also washed out and eliminated together with the condensate. irend Motor speed = airend speed oupling Drive motor The energy-saving, directly-coupled drive The advantage of this drive is not just the elimination of transmission losses. The drive motor and the airend are joined by the coupling and its housing into a compact and rigid unit that needs no regular maintenance apart from greasing the motor bearings. Should the coupling ever need to be replaced it can be done in just a few minutes without any disassembly of the unit. The opening in the coupling housing is more than adequate to replace the two coupling sections. SF module There are good reasons why frequency converters from Siemens are used for s variable speed compressors. onverter efficiency is the maximum possible; there is outstanding communication between the SF module and SIGM ONTROL and the compressor controller itself is based on a Siemens industrial computer. Worldwide service is guaranteed at all times because of Siemens' global presence. Finally, the SF module and SIGM ONTROL are tested and certified both as individual components and as a system to EM directive EN 550 for class industrial power supplies. SD/SD/SDX SF up others to up to,00 rpm,000 rpm Low speeds Every SD/SD/SDX SF machine has the same mechanical components as those used in fixed speed machines. This not only ensures highest reliability and availability but guarantees optimum energy efficiency as well. The lowest speed and the largest airend possible - the maximum speed of an SD/SD/SDX SF is only around,00 rpm - are, after all, the basic requirements for really economical production of compressed air. dded to this is longer life and lower servicing effort. The use of standardised drive motors is another contribution toward lasting availability. Flexible selection The wide range of directly-coupled SIGM PROFILE airends produced by make it possible to select the one that works most efficiently within the and volume required. The right choice of airend results in the most economical -to-frequency profile for the SD/SD/SDX SF machines. -to-frequency profile that ensures maximum flexibility both in and volume under the aspect of highest possible economy is programmed into the SF module.

The operational state of the compressor is quickly ascertained with the help of coloured LEDs. four-line, plain text display, easily understood icons and touch keys allow fast set-up and operation. SIGM ONTROL regulates and monitors the compressor and the T and SF modules fully automatically and shuts the machine down immediately in the event of an alarm. Interfaces are provided as standard for connecting a modem, a second compressor and for connection to a data network (Profibus DP). Low specific power requirement Large, low speed airends are more efficient. They deliver more compressed air for the same drive power, not just at full load but over the whole range of control an important aspect as far as variable speed machines are concerned.. kw per m³/min is taken as a reference value for very good specific power requirement (referred to the effective electrical power consumption of an SF compressor at ).
