What do you look for in a compressor with variable frequency drive and refrigeration dryer? s a user, you expect maximum efficiency, reliability and consistent air quality from your compressed air system. ir system investment That may sound Maintenance costs simple, but these advantages are influenced by many different factors: Energy costs, for example, taken over the lifetime of a compressor, add Energy costs up to a multiple of Potential energy savings investment costs. Efficient energy consumption therefore plays a vital role in every compressed air system, as does compressor reliability. In addition, the compressed air should be free from condensate and treated to provide the required level of quality appropriate for the specific application. These measures ensure enhanced system reliability and significantly reduce maintenance costs in the air distribution network, pneumatic controls and 8 all other associated compressed air powered equipment. T SF Integrated Modular Design s solution: Versatile modular design vailable with a modular refrigeration dryer and/ or SF variable frequency drive, SD-, SD- and SDX rotary screw compressors fulfil every customer requirement: They are highly energy efficient, quieter than quiet, require minimal maintenance, are extremely reliable and deliver the very best in air quality.

SD T SDX T with compact refrigeration dryer Dependable centrifugal separator centrifugal separator with an electronically controlled EO DRIN is installed between the compressor and the dryer. This ensures safe, efficient initial separation and drainage of the condensate even under conditions of high ambient temperature and humidity. Innovative: The SD T, SD T and SDX T series The new SD T, SD T and SDX T rotary screw compressor packages meet every customer requirement, as they combine maximum reliability with outstanding efficiency. With the addition of the integrated refrigeration dryer module, these high-performance units are transformed into complete air supply systems. Easy to maintain, the dryer is contained in its own separate housing within the unit to prevent exposure to heat from the compressor package, considerably increasing operational reliability and enabling use in ambient operating conditions of up to +5. SD 0 T rear view Thermal insulation is omitted from the illustration Refrigeration dryer with EO DRIN The refrigeration dryer s electronically controlled EO DRIN operates according to the condensate level. This eliminates the losses associated with conventional condensate drain systems and considerably enhances the reliability of the compressed air supply. Stainless steel plate heat exchanger The dryer`s stainless steel plate heat exchanger is resistant to corrosion, clogging and deposits. Even with a fluctuating airflow the heat exchanger reliably separates the accumulating condensate from the air. The dryer s components and piping are designed to provide exceptional operational safety and reliability. Turnkey operation The integrated refrigeration dryer module is directly attached to the standard unit and is ready for immediate use. The modular design allows the components in the dryer to be generously sized and easily accessible for maintenance. It also prevents exposure of the refrigerant dryer to any heat from the compressor package. Individual apertures and logical construction ensure outstanding reliability in ambient temperatures of up to +5, significantly increasing compressed air availability. SIGM ONTROL The SIGM ONTROL compressor controller constantly monitors the compressor, refrigeration dryer and condensate drains. If required, messages from the dryer can be defined as alarms and forwarded to a control centre.
SF Ultimate efficiency Perfect performance - even at high ambient temperatures The generously-sized SF module with its efficiently-cooled control cabinet allows trouble-free operation in ambient temperatures up to +5. Maximum flexibility: The SD SF, SD SF and SDX SF series Every rotary screw compressor is equipped with a large, efficient airend featuring high performance SIGM PROFILE rotors. The airends in SD, SD and SDX units are powered by a direct drive system that eliminates the transmission losses associated with gear drive systems, enabling these compressors to provide significant energy savings. onsiderable savings can also be achieved with the addition of a SIGM FREQUENY ONTROL (SF) module. Depending on the size of the compressor installation, energy consumption in larger compressed air systems can be reduced by up to 50%. Pressure in Precision control ir delivery from a SD SF, SD SF or SDX SF compressor can be matched to actual air Pressure ± 0. demand, according to required system, by continuously adjusting drive motor speed Time (and therefore the airend) within its specified control range. Depending on the buffer capacity of the downstream air network, it is therefore possible to precisely maintain to within ±0. and, as a result, to reduce maximum system. This can lead to significant savings, as each reduction in amounts to a 7 percent reduction in energy consumption. onstant SDX 6 T SF front view Other variable speed compressors SF compressors Transmission losses Soft start with no current spikes Zero Interference: The electromagnetic compatibility (EM) of the components and of the complete machine has been tested and certified in accordance with all applicable regulations. Energy consumption Maintenance costs SD SF, SD SF and SDX SF compressor packages are highly efficient direct drive units featuring variable speed control. With high-efficiency performance throughout the entire control range, large, low speed airends featuring the energy saving SIGM Profile have significant advantages over smaller, high speed airends. ll packages are designed to operate at full load, 7 days a week, yet require no additional maintenance. Triple savings with : drive Significantly increasing reliability and service life, direct drive reduces the number of components needed in comparison with gear drive and eliminates the associated transmission losses. Sound levels are also considerably lower. The benefits speak for themselves: efficient power transmission, optimal power consumption and reduced servicing / downtime costs. % full load current 800% 700% 600% 500% 00% 00% 00% 00% 0 % Direct start Star-delta start Soft start Soft start allows a gradual increase SF packages in drive motor current from zero to full load, enabling almost unlimited motor switching frequency i.e. the number of times the motor can be switched on within a defined time period without overheating. urrent peaks that can potentially cause damage to power systems and equipment are reliably eliminated without the need for expensive electronics. In addition, the continuously variable acceleration and deceleration of moving parts reduces dynamic loading.
SD/SD/SDX T SF Eight Decisive dvantages SIGM PROFILE airend specific drive power can be used to turn a smaller 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 investment cost of the larger airend is quickly recovered by the energy saved during operation. 5 Efficient stainless steel condensate separator The separator tank in the refrigeration dryer is made of stainless steel and is therefore completely corrosion resistant. deflector plate forces the compressed air that streams into the separator into circular motion. The air then flows through a stainless steel wire mesh that ensures 99.9% water separation from the air. This figure remains almost constant, despite fluctuating airflow, reliably maintaining the required dew point. Solid particles are also washed out and eliminated together with the condensate. Energy-saving : drive The advantages of this drive system are not just limited to the elimination of transmission losses. The motor and airend are joined by the coupling and its housing to form a compact and durable unit that, apart from greasing of the motor bearings, requires no regular maintenance. Should the coupling ever need to be replaced, it takes just a few minutes without any disassembly of the unit, as the opening in the housing is more than large enough to replace the two coupling sections. 6 SF module Siemens frequency converters are used exclusively in s speed controlled compressors for several reasons: Siemens manufactures the industrial Pbased SIGM ONTROL compressor controller, which enables seamless communication with the SF control cabinet. Furthermore, the worldwide presence of Siemens ensures dependable service. The SF control cabinet and SIGM ONTROL are lass tested and certified as per electromagnetic compatibility regulation EN 550, both as individual components and as an integrated system. SD/SD/SDX T SF up to 600 rpm Others up to 7000 rpm Low speed operation Each SD SF, SD SF and SDX SF compressor has exactly the same mechanical components as those used in 's fixed speed compressors. This not only ensures unrivalled reliability and compressed air availability, but also guarantees optimum energy efficiency. The most efficient method of producing compressed air is by using large, low speed airends airends in SD/SD/SDX SF compressors have a typical maximum rotation speed of approximately 600 rpm. Further advantages include long service life and reduced maintenance requirement. The use of standardised drive motors also contributes to long-term compressed air availability. 7 Flexible adjustment The wide range of : drive airends available makes it possible to select the one that works most efficiently within the and performance range required. This ensures that every SD/SD/SDX SF compressor operates with the most efficient -frequency profile. Furthermore, the SIGM ONTROL compressor controller is equipped with a -to-frequency profile that guarantees maximum flexibility for air delivery and whilst providing best possible efficiency. Pressure in 0. steps 0 0. steps 7.5 0. steps 5 50 00 Hz SIGM ONTROL ased on robust P architecture, the SIGM ontrol offers the possibility of Dual, Quadro, Vario and ontinuous control. learly marked navigation and input keys on the user interface are used to move around within the menu options of the four line alpha-numeric display. This powerful compressor controller can also display information in any of 0 selectable languages at just the press of a button. The SIGM ONTROL automatically controls and monitors the compressor package. The Profibus interface enables exchange of data and operational parameters allowing the SIGM ontrol to communicate with other air management systems such as the SIGM ir Manager. Interfaces are provided as standard for connection of a modem, a second compressor in base-load sequencing mode and for connection to data networks (Profibus DP). 8 Specific power is the key Large, low speed airends are more efficient than small high speed airends because they supply more air for the same drive power. This is not just the case at full load, but also applies throughout the entire control range, which is particularly important for variable speed machines. The specific energy requirement of 6. kw per m³/min for a SF compressor operating at 7.5 can be considered as an excellent indication of the machine's efficiency. Variable frequency controlled compressors are only truly efficient if they have low energy consumption throughout their entire control range. 6. kw/m³/min at 7.5
