MORE COMPRESSED AIR FOR LESS ENERGY
KAESER rotary screw compressors All-in-one systems
From the workshop to industrial plants, from the mine to the petroleum refinery: More and more customers throughout the world rely on Kaeser quality compressed air systems “Made in Germany” and benefit from optimum compressed air availability combined with low life-cycle costs.
EXCEPTIONAL ENERGY BALANCE
TIME SAVING MAINTENANCE AND OPERATION
EXCEPTIONAL MATERIAL QUALITY AND DURABILITY
SAVE ENERGY WITH SIGMA PROFILE
Every KAESER rotary screw airend is equipped with energy saving SIGMA PROFILE rotors. Components manufactured to the highest standards and precision aligned roller bearing ensure long service life with maximum reliability.
ENERGY-SAVING 1:1 DRIVE
The motor and airend are joined by the coupling and its housing to form a compact and durable unit that is virtually maintenance-free. Furthermore, reliability and service life are increased through elimination of wear and transmission losses, as 1:1 drive reduces the number of components needed in comparison with gear drive.
SIGMA CONTROL 2
The SIGMA CONTROL 2 ensures efficient control and system monitoring. The large display and RFID reader ensure effective communication and maximum security. Multiple interfaces provide exceptional flexibility. The SD card slot makes updates quick and easy.
THE FUTUTRE, TODAY : IE4 MOTORS
KAESER is currently the only compressed air systems provider to equip its compressors with Super Premium Efficiency IE4 motors as standard, thereby ensuring maximum performance and energy efficiency.
LOW SPEED OPERATION
Large, low speed airends are more efficient than small high speed airends because they supply more air for the same drive power. Low speeds mean less wear and consequently less maintenance costs.
QUIET AND EFFICIENT RADIAL FAN
The quiet and powerful radial fan draws in cool ambient air through the cooler. Its high residual thrust can deal with partial clogging of the cooler and still have enough reserve to allow connection of a longexhaust duct. In addition, the radial fan consumes significantly less drive power than conventional axial fans, saving even more energy.
ELECTRONIC THERMO MANAGEMENT
The innovative Electronic Thermo Management (ETM) system dynamically controls fluid temperature to provide reliable prevention of condensate accumulation. This enhances energy efficiency, forexample, by enabling heat recovery to be precisely tailored to meet customer’ exact needs.
How KAESER rotary screw compressors work?
Atmospheric air is drawn through the inlet air filter, cleaned, and then passes into the airend where it is compressed. Specially developed SIGMA FLUID
is injected into the airend to serve as coolant, lubricant and sealant. Under normal conditions the air reaches a temperature of only approx. 80 °C during compression. The compressed air is then separated from the cooling fluid (approx. < 2 mg/m3) in the separator and from there passes through the min- imum pressure valve to the aftercooler. The separated, cooled and filtered cooling fluid is re-injected into the airend. In the aftercooler the air is cooled down to between 5 and 10 K above ambient and most of the moisture carried in the air is consequently removed before the air finally leaves the compres- sor at the outlet.
