7 However, each unit usually requires its own floor space,which in many cases is at a premium. Even if sufficient roomis available, the principle of Space is Money still applies. Therefore, the ideal solution would be a compact compressed airsystem that requires minimal floor AIRTOWER solutionModular in design, KAESERAIRTOWERS incorporate apowerful Rotary Screw compressor mounteddirectly above a high-efficiency refrigeration airdryer, consequently eliminating the need for additional floor space. KAESER AIRTOWER systems fulfil all of your compressed airneeds: they are efficient, quieter than quiet, require minimalmaintenance, are extremely reliable, simple to install anddeliver the very best in air designUnlike packaged systems that are crammed into one cabinet, a majordesign feature of the KAESERAIRTOWER range is that the com-pressor and dryer are both completelyseparate, independently functioningunits.

8 This means that each can beoperated individually making it possibleto isolate and service the dryer whilstthe compressor is operating. Containedin its own separate cabinet there issufficient space to allow the dryercomponents to be generously sized yeteasily accessible. Servicing made easy:Component accessibility is optimisedthrough simplicity of design, wideopening doors and removable panelsthat greatly simplify compressor can be accessedthrough the door 1, hinged lid 2 andremovable panel 3. When panel 4 is removed the dryer unitcan be pulled out like a drawer so thatall components to be serviced areaccessible. Behind doors 5 and 6 are the separatecontrol cabinets of the compressor anddryer, electrically equipped to EN 60204, protected from dust and splash-proof to SIGMA PROFILEEach KAESER Rotary Screw com-pressor airend uses SIGMA PROFILE rotors, specially developed byKAESER, that require approximately15 percent less energy than conventional rotors with the same airdelivery capacity.

9 SIGMA CONTROLThe SIGMA CONTROL automaticallycontrols and monitors the compressorpackage. It is a robust PC-basedindustrial computer with real-timeoperating system and updatecapability. A plain text display andtraffic-light style LEDs clearly showthe operational state of the machineat a glance. A choice of four controlmodes is available to allow selectionof the most appropriate for a specific are provided for modem / printer, a secondcompressor for base-load sequencing or a data network(Profibus DP) connection that enables system access viaKAESER s Teleservice facility. The refrigeration dryer isequipped with an independent control panel andon/off/emergency stop Air as StandardThe Airtower produces dry air with apressure dew point of +3 C reliablyand cost-effectively.

10 KAESER AIRTOWER systems haveredefined the concept of compactcompressor packages by usingcomponents of the highest quality. A centrifugal separator equipped withan electronic ECO DRAIN is installedupstream from the dryer to ensurereliable, efficient air drying. Condensate accumulating inthe refrigeration dryer is removed safely and effectivelywithout pressure loss via an electronic ECO DRAIN condensate space requirement - maximum systemflexibilityAIRTOWER versions 3 to 11 have a footprint of only m . The compressor and dryer are both designed as completely separatefunctioning modules. Unlike compact single-cabinet solutions, thismeans that each can be operated independently of the other, makingit possible to isolate and service the dryer whilst the compressorcontinues to deliver compressed Maximising SpaceThe Screw compressor a separate unitIntelligent design meansthat no additional floorspace is required for therefrigeration dryer Compact footprintAIRTOWER 3 to 11: m2 Fully piped and readyto use, the standardAIRTOWER version issimply connected to anexisting air receiver viaball-valve and alternative versionallows the receiver to beconnected upstreamof the dryer.
