Energy-saving compressor airendwith SIGMA PROFILE rotors

Lower life-cycle costs

More air, more savings...

The KAESER SIGMA PROFILE, introduced in 1975 and continually enhanced ever since,brings power savings of up to 15 percentcompared with conventional screw airend rotor profiles.

All KAESER rotary screw airends feature this energy-saving rotor profile and are designed to ensure maximum energy-efficiency.

The generously-sized, precision-aligned rollerbearings and close-tolerance machiningguarantee long service life and outstanding reliability.

A specific drive power can be used to turn a smaller airend at high speed ora larger airend at slow speed. Larger, lower speed airends are more efficientand deliver more compressed air for the same drive power. This is why KAESER manufactures low speed airends with optimised rotorprofiles. Every KAESER rotary screw compressor quickly pays for itselfthrough significant savings in energy costs.

Energy costs taken over the lifetime of any compressor add up to manytimes that of the initial capital cost, which can make any purchase price

difference a false economy. Efficiency and reliability are vital in the production of compressed

air and KAESER achieves these objectives with quality, durable components that are built to last.

Energy-saving KAESER rotary screw compressors can help users to significantly reduce their compressed air costs.

The SIGMA controller automatically regulates and monitors thecompressor. It is a robust PC-based industrial computer with real-time operating system and update capability. System operating status can be viewed at a glance via user-friendly ‘trafficlight’ LEDs. The four-line plain text display, touch keys and iconsensure ease of operation.

In case of an alarm the safety shutdown sequence immediatelyswitches the compressor off. The SIGMA CONTROL offers the possibility of Dual, Quadro and Vario Control modes and the mostefficient control mode can be determined directly onsite using theprogrammable compressor duty cycle display feature. Interfaces are provided as standard for connection of a modem orprinter, a second compressor in base load sequencing mode andfor connection to a data network.

Save energy with theKAESER SIGMA PROFILE

Every KAESER rotary screw airend isequipped with energy-saving SIGMA PROFILE rotors. Meticulous engineering tothe highest quality standards and precision-aligned roller bearings ensurelong service life and outstanding reliability.

SIGMA CONTROL

The compressor controller is a robust PC-based industrial computer with a real-time operating system and update capability. System operational status canbe displayed in any one of 30 selectablelanguages, whilst ‘traffic light’ style LEDsindicate status at a glance.

Optimised oil separation system

The combination of optimum flow separation and the special separator cartridge results in a minimal fluid contentof less than 2 mg/m³ in the outlet air. Theseparator system also requires very littlemaintenance.

Automatic belt tensioning

The automatic belt tensioning device ensures consistent transmission efficiencyand excellent drive-system reliability.

Cooling air filter mats

Ambient air used for cooling is contaminated to some degree, but the filter mats through which the air is drawninto the cabinet prevent the cooler fromclogging.

KAESER rotary screw compressorswith V-belt drive to 22 kW

Atmospheric air is drawn through the inlet filter into the airend where it is compressed. The airend is driven by theelectric motor .

Specially developed SIGMA FLUID is injected into the airend to serve as coolant,lubricant and sealant. Under normal conditions the air reaches a temperature ofonly ~80°C during compression.

A three-stage separator removes the cool-ing oil from the compressed air. The fluidpasses through the cooler , the micro-filter and back to the point of injection. A thermostatic valve regulates andoptimises the fluid temperature.

The air emerges from the separator cartridge with a remaining fluid content of less than

2 mg/m³, passes through the minimumpressure check valve and finally through the after-cooler.

In the after-cooler the air is cooled down tobetween 5 and 10 K above ambient. Mostof the moisture carried in the air is removedin the after-cooler. The air finally leaves thecompressor at the outlet.

KAESER screw compressors with V-belt drive provide outstanding economy, efficiency and reliability. KAESER was one of the first compressor manufacturers to introduce the V-belt drive system. TheKAESER drive is characterised by an automatic tensioning device that ensures constant transmission efficiency and reduced maintenance costs.Furthermore, rotary screw compressors with V-belt drive are especially

Energy-saving 1:1 drive

1:1 drive reduces the number of components needed in comparison withgear drive, increasing reliability and service life through elimination of wearand transmission losses.

Innovative radial fan

Quiet and efficient – these are the mostimportant characteristics of a radial fan.Low peripheral speed means low noise.Power consumption is up to 50 percentlower than a comparable axial fan. Another advantage is the high residualthrust developed that allows the use ofexhaust ducting without the need for anadditional extractor fan.

SIGMA CONTROL

The compressor controller is a robust PC-based industrial computer with a real-time operating system and updatecapability. System operational status canbe displayed in any one of 30 selectablelanguages, whilst ‘traffic light’ style LEDsindicate status at a glance.

Low speed operation

Large, low speed airends are more efficient than small high speed airendsbecause they supply more air for thesame drive power. Low speeds mean lesswear and consequently less maintenancecosts.

In compressed air packages featuring 1:1 direct drive the motor drives the airend directlywithout transmission loss via amaintenance-free coupling. 1:1direct drive rotary screw compressors provide outstandingperformance and enable significant savings.

KAESER’s comprehensive rangeof specially designed airends aremanufactured and developed tomeet every compressed air user’sneeds.

In addition to improved cooling efficiency, the system has further benefits to offer. The inside of the cabinet remains clean because surrounding air is drawnthrough the cooler into the cooler box and then exhausted directly upward outof the machine. Contamination from the cooling air is trapped on the outside ofthe cooler. Clogging is easily noticed and quickly cleaned off without the needfor any dismantling work. Operational reliability is improved and maintenance requirement is significantly reduced.

KAESER rotary blowers with OMEGA PROFILE are used inpressure/ vacuum applications for drying, aerating wastewater clarifiers, conveying powder or granular material,

cleaning by suction, inspection and packaging.

More and more users chooseKAESER compressors

Tunnelling and water pollutionprotection

Diesel-powered MOBILAIR compressorsare as economical as they are versatile.They are used in a wide range of applications, such as supplying air fortunnel construction projects (e.g. theElbe Tunnel) or for oil booms used for oilspill containment in harbours.

PET bottle production

KAESER has developed a remarkably eco-nomical system solution for this growing field of application. The KAESER PET bottle production system comprises a lowpressure stage (rotary screw compressor,control air), a high pressure stage (boost-er, blow moulding) and efficient refrigera-tion drying. In addition to outstanding system performance, air users benefitfrom low investment and operating costs.

Dust evacuation, packaging, filtration

KAESER rotary screw vacuum packages withthe special KAESER vacuum airend are justas much at home evacuating, testing, drying,and degassing as they are for filtration or filling bottles and tubes. These units are alsoequipped with the innovative PC-based SIGMA CONTROL compressor controller.

Trade and industry

The majority of industrial compressed air requirements are met by rotary screw compressors, which are also being increasingly used in trade and workshop applications. KAESER screw compressorswith SIGMA PROFILE rotor airends reflectthis growing trend, as more than 200,000 ofthese economical and reliable systems arecurrently in service throughout the world.

Cathode ray tube production

Drying of the internal vapour-deposited coating on cathode ray tubes requires compressed air of the highest quality. The airmust be ‘dry’ and ‘oil-free’ to maintain consistently high product quality standards.Application-specific compressed air systemsdesigned and installed by KAESER ensuremaximum reliability and efficiency.
