2 What do you expect from a compressor? As a compressed air user, you expect maximum effi ciency and reliability from your air system. This sounds simple, but these advantages are infl uenced by many diff erent factors: Energy costs, for example, taken over the lifetime of a compressor, add up to a multiple of investment costs. Compressor system investment Maintenance costs Energy costs Potential energy savings Effi cient energy consumption therefore plays a vital role in the production of compressed air, as does reliability of the compressor. In many cases, a reliable compressed air supply is essential to guarantee maximum performance from valuable production systems. Reliability also ensures a supply of constant quality compressed air that optimises effi ciency of the air treatment equipment downstream from the compressor. With regards to sound protection, it is always better to keep noise emissions to a minimum from the outset by using a quiet compressor rather than have to retro-fi t sound protection measures later on. Last but not least, a truly effi cient compressor is simple to maintain. ASK The Dependable Powerhouse s Solution: The ASK Series 's new ASK rotary screw compressors fulfi l every customer requirement: they are highly energy effi cient, quieter than quiet, require minimal maintenance, are extremely reliable and deliver the very best in air quality. All of these advantages are aided through innovations in compressor design, drive system technology, cooling and ventilation, silencing and maintenance methods. As a result, the ASK series of rotary screw compressors is a meticulously engineered and reliable product range built to 's renowned high quality standards. SIGMA PROFILE The SIGMA PROFILE, developed by Kaeser Kompressoren in, saves up to % in energy consumption compared with conventional rotor profi le designs. The airends in ASK units use even further refi ned rotors. SIGMA CONTROL The internal compressor controller is a robust PC-based industrial computer with a real-time operating system and update capability. 'Traffi c light' style LEDs clearly indicate system operational status. The ASK is also available with the SIGMA CONTROL BASIC controller. Longer service intervals reduce costs An example of how carefully considered design leads to improved economy is demonstrated by the easy to clean / change fi lter mats that prevent contamination from entering the compressor unit. They not only enable extended service intervals but also help to considerably increase the thermal reserve of ASK units. Inlet valve Electric motor V-belt drive with automatic belt tensioning SIGMA PROFILE airend Fluid separator with cartridge Fluid cooler Compressed air after-cooler SIGMA CONTROL or SIGMA CONTROL basic Refrigeration dryer (with ASK T and ASK T SFC) ASK T up to approx rpm others up to 000 rpm Quietly powerful As the most efficient way to achieve a given drive power, use large, low speed rotary screw airends. This ensures that the specific power is always within the optimal range. ASK units use a flexible V-belt drive system to precisely determine airend speed dependent upon the airend being used. Further advantages of low airend speeds are that components are subjected to less wear and consequently last longer the associated lower noise emissions are of particular importance for compressors installed directly in work environments.

3 ASK Maximum Flexibility Available with refrigeration dryer Permanently dry compressed air Space saving, energy effi cient compressed air generation and treatment is possible by selecting the ASK T integrated refrigeration dryer module option. 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. The dryer also features an energy saving mode. Variable speed option Integrated frequency converter For applications with fluctuating compressed air demand, the ASK compressor package is also available with a SIGMA Frequency Control (SFC) module. The SFC module is integrated within the compressor s control cabinet and, just like the SIGMA CONTROL, is manufactured to the very highest standards by Siemens. Stainless steel condensate separator The refrigeration dryer's compact stainless steel condensate separator ensures optimal condensate separation even with fl uctuating fl ow volumes. The upstream contamination-proof heat exchanger also cools down the compressed air to make this possible. EMC certified Electromagnetic compatibility (EMC) is particularly important for variable speed compressors. All ASK SFC components and systems are tested for electromagnetic compatibility to Class A (industrial) and Class B (domestic) in accordance with EN 0. Electronic condensate drain The refrigeration dryer's electronically controlled ECO DRAIN 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. Energy savings Energy costs account for over 0 percent of total compressed air costs. This can therefore amount to a significant sum even for smaller compressed air systems, which is why uses the very latest technology to ensure that every compressor provides best possible energy efficiency. These compressors form the basis for reliable and cost-effective compressed air production as part of a correctly planned and integrated compressed air supply system. Compressor system investment Maintenance costs Energy savings Energy costs Alternative controller: SIGMA CONTROL BASIC Efficient cooling air flow system Cooling air for refrigeration dryer Inlet air Alternatively, if the comprehensive counication capability of the SIGMA CONTROL is not required, ASK models are also available with the SIGMA CONTROL BASIC compressor controller. This controller offers the possibility of Dual and Quadro control and operates via an electronic sensor with low switching differential. With the addition of an optional plug-in memory module, the SIGMA CONTROL BASIC is also able to counicate with the SIGMA AIR MANAGER master controller. This feature enables the compressor to be easily integrated within a centrally controlled compressed air installation. Just like 's larger units, ASK compressors also have separate air intakes for the air/fluid cooler, motor and compressed air, resulting in significant reserves even at high ambient temperatures. Taking in motor cooling air from the surroundings ensures reliable and effective motor cooling even under adverse conditions. The compression process is also enhanced by directly sucking in air for compression from the ambient surroundings. 's modular design concept enables refrigeration dryers in T units to be installed in their own separate housing and to have their own individual cooling system, significantly contributing to high efficiency and reliability.
