6ScrewcompressorsG- / V-DRIVECompressor output with high enduranceThe G-DRIVE and V-DRIVE series offer consistently highperformance as well as numerous features for particularlyreliable, energy-efficient operation and convenient maintenance. There are various useful extensions available forthe latest generation of ALMiG screw compressors: anefficient heat recovery system with a constant temperature, an integrated refrigeration dryer which is preciselydesigned for the delivery volume of the system, as well asthe latest controllers to network your entire compressedair station. The system extensions do not affect the footprint of the compressor at all.Optional integrated refrigeration dryerIn this version, the refrigeration dryer is integrated in thesystem to save space. The compressor is used to supplythe dryer with power, control it and protect it againstfreezing if operated at "underload". The parameters of therefrigeration dryer are exactly tailored to the respectivekW class and the dryer cannot be "bypassed".Energy-saving speed controlAll variants are also optionally available with energysaving speed control.This is where the highly efficient direct drive comes intoplay: the high-frequency drive motor operates with outstanding efficiency over the entire speed range.The operating pressure can be adjusted steplessly from5 to 13 bar. The high-quality frequency inverter is easy toaccess in the control cubicle – an optimised cooling airguide provides optimum ventilation. Inverters and cablesare electro-magnetically shielded.Heat recovery systemAll our systems are designed so that an integrated heatrecovery system can be fitted into them – either directlyat the factory or as a subsequent retrofit. With thissystem, the energy consumed for the generation ofcompressed air can be converted almost entirely to usableheat; for example, as hot water for feeding into heatingsystems or for heating process water or industrial water.The constant temperature of the heat recovery systemensures reliability.Reduced service costsThe G-DRIVE and V-DRIVE screw compressors are veryeasy to maintain: all components are easily accessiblefrom one side and the large sound-insulating doors areeasy to remove. This reduces the maintenance and downtimes to a minimum, and ensures that the service costsare completely manageable.ApplicationIndustryPower output30 kW - 75 kWVolume flow acc. to ISO 1217(Annex C-1996)G-Drive: 3.92 – 13,54 m3/minV-Drive: 1.77 – 13.00 m3/minOperating pressure5 – 13 bar; stepless settableCoolingAir-cooled (standard)Water-cooled (option)DriveV-Drive: Direct and speed-controlledG-Drive: GearboxMotorEnergy efficiency class IE 3; IP 55protection, protection class F The latest controllers are used to network the entire compressed air station Modular system concept developed formaximum energy efficiency An efficient heat recovery systemwith a constant temperature An integrated refrigeration dryer whichis precisely designed for the deliveryvolume of the system

10ScrewcompressorsG-DRIVE THighest efficiency in classWith the two stage G-Drive T series ALMiG sets newstandards in energy efficiency. By compressing air in twostages they achieve a specific performance which is atthe highest level. Therefore, the G-Drive T compressorseries offers a higher volume flow with a lower inputpower consumption, in comparison to an equivalent singlestage compressor. Low rotational speeds and lower internalcompression ratios within the compressor stages increasethe efficiency, reliability and lifetime of the compressorelements. State of the art efficiency, coupled with a lowsound level and low service costs, makes the 2-stagetechnology very interesting for industrial compressed airusers.The G-Drive T offers all these benefits, plus a compactfootprint due to its well-thought-out design. With a lookto Industry 4.0, the controller of the compressor has allthe required functionalities to communicate with commonindustrial company systems. Or simply use the cloudservice to monitor the compressor from anywhere.Advantages:Application Due to the high efficiency of the compressor maximumenergy savings can be achieved and the life cycle costsof the machine can be reduced Up to 15% greater energy savings in comparison to asingle stage compressorIndustryPower output90 – 250 kWVolume flow acc. to ISO 1217(Annex C-1996)14,6 – 51,5 m3/min Durable and reliableOperating pressure Low differential pressures5 – 13 bar Reduced heat loadCooling Easy maintenance and serviceThe unique design of the airend integrates the first andsecond stage into one compressor element. The rotors ofboth air ends achieve the optimal speed due to the geardrive.An efficient compression is achieved by using a cooling oilmist for interstage cooling. This controlled amount ofoil enables at the same time to avoid condensate in thesecond stage.
