Resulting in the largest range of air compressors and blowers within our industry. Through continuous research and development, we achieved a new milestone, setting the standard for air purity as the first manufacturer to be awarded ISO 8573-1 CLASS 0 certification. CLASS 0 certification means zero risk of oil contamination from our products.Class 0: The Industry StandardThe CO2 boosters are completely oil-free.Components, such as the long distance piecebetween the crankcase & the cylinder and the oilwiper at the piston rod, have been carefullydesigned to ensure oil-free air.Class 0 by design5• Less vibrations for longer component life.• Reduced forces and torques to minimize foundation requirement.• Reduced specific load on piston wear bands for longer life.• Easy access to all parts and easily removable crosshead guide.• Skid mounted, plug & play compressor.• Cooled by forced water circulation to minimize temperatures, increasing efficiency and reliability.• For water saturated gases:- Discharge valves at the bottom, in accordance with API 618.- Non-accumulation of condensate for increased life time of piston rings.Horizontal design for reducedmaintenanceSafe cylinders CO2 booster• Pistons are made of composite aluminum, stainless steel or other materials according to the process.• Piston rods in stainless steel or 42CD4 (hardened & tempered steel) with API 618 compliant hardness coating (induction or plasma) ensuring long life of packing rings.• Piston is positively locked by Superbolt® on the piston rod: a highly secure tightening technology.• Piston rings are made of composite PTFE for long life.• Superior stainless steel valves, precise sizing and selection or each application for high efficiency and long lasting performance.• Wide port area, ensuring minimal pressure loss.• Customized discs (PEEK or stainless steel) for each application.• Fail-safe type suction valves (unloading on air or nitrogen), when required by the process.• Low piston speeds and low revolution speeds for low temperatures.• Lower gas temperatures ensure longer component life.• Excellent cylinder cooling due to forced cool water circulation.• Extremely reliable drive system with sleeve bearings and double bearings on the flywheel side for reduced wear.• Excellent lubrication of the components for reduced wear.• IP55 rated motor for maximum reliability• Superior motor protection for increased reliability, reduced maintenance cost and less downtime.• IP54 rated cubicle design for better protection against water and dust.• Ease of monitoring for increased reliability and checking machine status remotely.• Elektronikon Mk5 compressor controller with optimized user experience.• Ease of use and monitoring for improved reliability.• Stainless steel connecting pipes for increased lifetime of components.• Flexible connections for cooler and cylinder for reduced stress on mechanical components.• Components (valves, piston rod packaging, cylinders) are specifically selected according to gas composition and humidity content.Reliable pistons and piston rods Superior valve qualityLong lasting performance due to low temperatures DrivePremium quality motorControl panelAdvanced monitoring systemHigh quality stainless steel components7Monitor with SMARTLINKKnowing the status of your compressed airequipment at all times is the surest way to achieve optimal efficiency and availability.Go for energy efficiencyCustomized reports on the energy efficiency of your compressor room.Increase uptimeAll components are replaced on time, ensuring maximum uptime.Save moneyEarly warnings avoid breakdowns and production loss.Smartlink: Fully connectedMost production processes create fluctuatinglevels of demand which can create energy waste in low use periods. By using the Elektronikon controller, you can manually or automaticallyswitch between two different setpoints to optimize energy use to reduce costs at low use times. The sophisticated algorithm runs the motor only when needed. As the desired setpoint is maintained while the drive motor’s run time is minimized,energy usage is kept to a minimum.LegendA =Power consumptionB =TimeC =Energy SavingDelayed Second StopDelayed Second StopCO2 boosterThe Elektronikon®unit controller is specially designed to maximize the performance of your compressors and air treatment equipment under a variety of conditions. Our solutions provide you with key benefits such as increased energy efficiency, lower energy consumption, reduced maintenance times and less stress… less stress for both you and your entire air system.Elektronikon Mk5The piston runs at low speed with long strokes,reducing the operating temperatures as well as thefriction for more efficient compression andincreased reliability.The cylinder is designed for flow and sizeoptimization to reduce energy consumption.The high efficiency coolers reduce the temperatureon the valves, rings and packings which results inless wear of the components and increasedreliability.A high efficiency motor is used as standard forreduced power consumption.Components designed for efficiency9CO2 boosterAll connections and instrumentation is installed and factory tested. This leads to reduced commissioning and installation time.The horizontal design and opposed arrangements in the CO2 booster lowers the vibration level of the machine.This reduces the wear of the unit and extends the lifetime of the wearing components. The reduced vibration level requires less foundation, increases the ease of installation and reduces the stress on piping and ancillaries.No special lifting devices are needed to conductmaintenance on wearing parts. Because of the horizontal design everything is easily accessible.Water connections are placed on the same side for ease ofconnections.1.Integrated cubicle2.Horizontal design for reduced vibrations3.Easy access to wearing parts for easeof maintenance4.Water connections11OptionsInlet separator: for wet CO2 applications•Test & materials certificate•Ancillaries•Customized & engineered solutions•CO2 boosterCO2 booster (50 Hz)CO2 22-195 - 5050127220.0120CO2 22-195 - 50192220.4 CO2 26-240 - 50158220.01 CO2 26-240 - 50240300.4 CO2 30-325 - 50212300.01 CO2 30-325 - 50322300.4 CO2 37-410 - 50269300.01 CO2 37-410 - 50410370.4 CO2 45-435 - 50320370.01 CO2 45-435 - 50488450.4CO2 65-750 - 5050527550.0120CO2 65-750 - 50792650.4 CO2 90-1110 - 50757750.01 CO2 90-1110 - 501136900.4CO2 132-1570 - 50501064900.0120CO2 132-1570 - 5015881320.4CO2 200-2280 - 505015821320.0120CO2 200-2280 - 5023722000.4CO2 250-3150 - 505021282000.0120CO2 250-3150 - 5031762500.4CO2 booster (60 Hz)CO2 booster 60CO2 22-195 - 6060135220.0120CO2 22-195 - 60200220.4 CO2 26-240 - 60164220.01 CO2 26-240 - 60245300.4 CO2 30-325 - 60221300.01 CO2 30-325 - 60328300.4 CO2 37-410 - 60276300.01 CO2 37-410 - 60410370.4 CO2 45-435 - 60333370.01 CO2 45-435 - 60495450.4CO2 65-750 - 6060540550.0120CO2 65-750 - 60805650.4 CO2 90-1110 - 60775750.01 CO2 90-1110 - 601150900.4CO2 132-1570 - 60601090900.0120CO2 132-1570 - 6016101320.4CO2 200-2280 - 606016301320.0120CO2 200-2280 - 6024302000.4CO2 250-3150 - 606021802000.0120CO2 250-3150 - 6032302500.4Notes15Atlas Copco AB(publ) SE-105 23 Stockholm, Sweden Phone: +46 8 743 80 00Reg. no: 556014-27202937 0744 00 © 2019, A t l a s C o p c o A i r p o w e r N V , B e l g i u m .
