2 hy boosters? The ability to offer compressed air at various s makes it one of the most versatile energy sources available. Special applications require specifi cally tailored solutions in order to achieve optimum effi ciency. Boosters are ideal for applications such as PET container production for example, where compressed air is required at a higher than the standard works or control air at particular points in the manufacturing process. In these cases, it is more economical to use the existing works air and boost it to the higher with a small local compressor, rather than to operate the whole compressed air system at the higher. Regulating the of a high network to suit low- applications (which account for most air usage) is simply a waste of money. KAESER offers a comprehensive range of high performance reciprocating compressors that are able to boost compressed air from a rotary screw compressor up to s as high as 45 bar(g). These machines are perfectly matched for use with KAESER KOMPRESSOREN s extensive range of rotary screw compressors and SIGMA PET AIR systems. Effective up to 45 bar Continuous research and development KAESER KOMPRESSOREN s strategy of continuous research and development ensures that every product provides exceptional performance and reliability. KAESER s wide range of boosters for example, features the very latest innovations in reciprocating compressor technology. These include newly designed compressor blocks with oil pumps and high efficiency coolers, both of which are essential for optimised high system operation up to 45 bar. In addition, design details such as pressurised oil lubrication and intensive cylinder cooling allow up to 1 percent duty cycles. KAESER compressor block esigned and manufactured by KAESER, the high- compressor blocks are available as two or three cylinder models and operate at low to ensure years of reliable and effi cient service. igh quality cylinder Every KAESER booster is equipped with super-precision cylinders, each finished by a special process to ensure imal oil consumption and negligible wear for maximum durability. Low temperatures T = 6-7 Kelvin Three-cylinder models are equipped with a fan-assisted aftercooler to ensure lowest possible compressed air outlet temperatures. A watercooled version with aftercooler is available to achieve even lower elta T results.

KAESER booster systems are in a class of their own however, as they are the product of decades of experience in compressor system design and guarantee continuous delivery at 45 bar.

3 Versatile range N series: Setting the standard For lower demand The smaller models in this range are best suited to applications where low flow rates are needed at s up to 4 bar. These compressors are equipped with one- or two-cylinder compressor blocks and are driven by high effi ciency s with up to 4 capacity. The quality of these units is second to none as all compressor blocks are designed, manufactured and assembled by KAESER. Optimum lubrication Equipped with an oil pump and oil fi lters, the new continuous oil fi ltration system available for aftercooler models N 253 G to N 21 G extends the oil change interval to 2 operating hours. Investment costs Maintenance costs Energy costs Energy saved with a premium efficiency Energy-saving s IE2/IE3 s consume less for greater output and provide outstanding effi ciency. Anti-vibration mounts N 6 G to N 153 G, air-cooled N 253 G to N 52 G, air-cooled For medium to large demand hen greater air fl ow rates are needed at s up to 45 bar then the mid-size and larger of the KAESER booster models are the natural choice. At the heart of every one of these houses is a precision machined two- or three-cylinder compressor block that delivers exceptional effi ciency. IE3 premium efficiency electric drive s up to 45 provide impressive performance. The manual (two-cylinder models) or automatic drive belt tensioning systems (three-cylinder models) ensure consistently effi cient transmission for reliable and economic operation. According to application, air-cooled or water-cooled aftercooler versions are available (N 253 G - N 52 only air-cooled, from N 21 G air- or water-cooled aftercooler). -cooled versions (N 21 G) are equipped with a separate fan-assisted aftercooler to keep the temperature differential between the and compressed air ( T) within close tolerances. To ensure optimum cooling performance with a T value of only approximately 5 K even at high ambient temperatures, the N 21 can be equipped with a water-cooled compressed air aftercooler. Maximum safety Oil, cylinder head temperatures and air discharge temperatures are continuously monitored on models N 253 G to N 52 G. The safety shut-down sequence is initiated via alarm signals. Efficient air cooler ighly efficient and maintenance-free, the cooler on two-cylinder compressors achieves very low compressed air discharge temperatures. Automatic belt tensioning On N 21 G models constant spring on the swing-frame maintains the drive belt at the correct tension to ensure virtually maintenance-free transmission. 1 2 Nitrogen For vibration-free and quiet operation the machine can be installed either on rubber mounts or on anti-vibration mounts. 2 Low maintenance = Savings The combination of the innovative forced lubrication system, precision machining and high quality components ensures imal maintenance requirement. Nitrogen compression Upon request, modifi ed versions of N-series systems are available for compression of nitrogen. Manual belt tensioning Quick and easy adjustment maintains optimum transmission on single- and twocylinder boosters. START CONTROL The START CONTROL provides reliable booster monitoring and control and also reduces the starting load. N 21 G, air-cooled or water-cooled aftercooler available
