Compresor de aire de tornillo rotativo con inyección de aceite Atlas Copco GA 110 VSD (VSD⁺ FF)

Descripción

The Atlas Copco GA 110 VSD is the model where the GA 110-160 oil-injected platform enters variable speed drive territory. It pairs a SmartInjection compression element with an oil-cooled motor rated at 110 kW, and the Full Feature branch adds an integrated refrigerant dryer to the same package. The versions cover two pressure bands in 50 Hz and two ratings in 60 Hz, with free air delivery between 95 and 407 l/s depending on the setting.

Where the GA 110 VSD Fits in the Oil-Injected Range

The GA 110-160 platform forms the upper end of the oil-injected screw range, and the GA 110 VSD stands at its gate with 110 kW of installed power at 50 Hz and 150 hp at 60 Hz. For a plant that has outgrown the smaller GA frames, this is the step into the big-machine class: the same duty continuity that the larger GA 132 and GA 160 models deliver, in a package that carries the lightest footprint of the range. Thousands of GA compressors run around the world in this duty class, and the installations concentrate where compressed air works around the clock: general industry, mining, power plants, metal plants and cement works. The jobs range from pneumatic tools, actuators and valves to ventilation, packing and palletizing machinery, soot blowing, fly ash handling and the pneumatic conveying of raw materials.

Two cooling layouts share the same platform. The air-cooled package releases the compression heat into the ambient air through its cooler section, while the water-cooled package connects to a cooling-water loop on site. The rated figures of the GA 110 VSD apply across both layouts, so the choice comes down to the infrastructure the plant already has.

Qué abarcan los términos «VSD» y «FF»

Two names describe the branches of the GA 110 VSD, and each adds one fact:

• VSD+ — variador de velocidad: el variador ajusta la velocidad del motor en función de la demanda de aire, lo que mantiene estable el rango de presión y permite un ahorro energético de hasta un 35 % a carga parcial.
• FF — Funcionalidad completa: el paquete incluye un secador de refrigerante, por lo que el secado se realiza dentro del compresor en lugar de junto a él, sin necesidad de trabajos adicionales de instalación de cables ni tuberías.

The GA 110 VSD is built as the GA 110 VSD+ – 8.5 bar and GA 110 VSD+ – 10 bar versions at 50 Hz, and as the GA 110 VSD+ – 125 psi and GA 110 VSD+ – 150 psi versions at 60 Hz. Every version combines with both the Pack and the Full Feature scope, so a plant picks the pressure band first and the depth of air treatment second.

Technical Specifications of the GA 110 VSD

The table below condenses the GA 110 VSD into its headline figures:

Datos nominales a 50 Hz

Each 50 Hz version of the GA 110 VSD is listed at three settings, and the FAD span inside every row covers the full VSD speed range at that setting. FAD is measured at 7 bar for the 8.5 bar version and at 9.5 bar for the 10 bar version:

The installed motor power stays at 110 kW across all settings, and the sound level holds at 77 dB(A) at the work station. The 8.5 bar version peaks at 407 l/s (862 cfm) on its minimum setting, and the 10 bar version peaks at 405 l/s (858 cfm). Moving from the minimum to the maximum pressure setting inside one version trims the peak flow by 51 to 80 l/s, which is the trade-off for the higher pressure band.

Datos nominales a 60 Hz

The 60 Hz versions keep the three-setting structure, with the pressure bands written in psi and the motor rated at 150 hp:

The 125 psi version peaks at 407 l/s (862 cfm) on its minimum setting, and the 150 psi version peaks at 405 l/s (858 cfm). At 60 Hz reference conditions, the pressure dew point of the integrated refrigerant dryer sits between 2°C and 3°C (36°F to 37°F).

Dimensiones y peso

The footprint of the GA 110 VSD depends on the branch, and the integrated dryer of the Full Feature adds length to the package:

The Full Feature package is 400 mm longer and 400 kg heavier than the Pack, because the refrigerant dryer module rides inside the same canopy. Width and height are shared at 1,785 mm and 2,020 mm, so floor planning comes down to the length difference between the two branches.

VSD+ Flow Matching and Energy Efficiency

Energy dominates the operating bill of a compressor: over 80 percent of its lifecycle cost is the energy it consumes, and compressed air generation can account for more than 40 percent of a plant’s electricity bill. The GA 110 VSD attacks that share with variable speed drive. The motor speed follows the air demand automatically, energy savings reach up to 35 percent, and the average lifecycle cost of the compressor drops by 22 percent.

The flow table above shows what that means for a machine of this size. Inside every setting, the FAD span runs from about a quarter of the peak output up to the full figure, so the GA 110 VSD tracks a demand curve that swings between weekend idling and full production without stepping between fixed load points. Plants that replace a loaded-unloaded fixed speed machine with this drive concept feel the difference directly in the electricity meter, because the motor no longer burns power pushing air against a closed inlet valve.

Estabilidad de la presión y rango de regulación

The integrated design holds the net pressure band within 0.10 bar (1.5 psi), and the compressor carries no speed windows that would jeopardize the savings or the stable net pressure. Turndown is maximized to 70-75 percent, so the GA 110 VSD keeps regulating deep into low demand instead of unloading early.

The highly efficient frequency converter sits in its own cubicle and stays stable in ambient temperatures up to 50°C / 122°F. The electric motor is designed for low operating speeds with dedicated attention to motor and compressor cooling, and the whole drive train is EMC tested and certified so compressor operation does not influence external sources and vice versa. Mechanical enhancements keep every component below critical vibration levels throughout the entire speed range.

Recuperación de energía en forma de agua caliente

El sistema opcional de recuperación de energía consta de un intercambiador de calor de acero inoxidable integrado con un circuito controlado por termostato. Recupera hasta el 78 % de la energía del motor integrado y del circuito de aceite del elemento en forma de agua tibia o agua caliente, sin que ello afecte negativamente al rendimiento del compresor. En las instalaciones con alimentación de caldera, procesos de lavado o carga de calefacción de espacios, ese calor recuperado sustituye al combustible o la electricidad que, de otro modo, la instalación tendría que consumir.

SmartInjection and the Sealed Drive Train

SmartInjection is the technology at the heart of the element. It provides the exact amount of oil the compression element requires, so the element works at peak efficiency across changing conditions instead of at a fixed compromise. Oil flows separately to the bearings for longer life and greater uptime, and the motor itself is oil-cooled, which removes the service interventions a conventional air-cooled motor needs. The drive train pairs the element with an IE4 class motor or better, and the air-cooled VSD FF branch carries an IE5 permanent magnet motor.

Protección IP66 y resistencia a las condiciones ambientales

The drive train of the GA 110 VSD is IP66 rated, which seals it completely against environmental dust and moisture. That rating is what lets the compressor run reliably in the toughest conditions: cement dust, mine particulates and humid intake air stay outside the drive train. The package operates at ambient temperatures up to 55°C / 131°F, the high ambient variant extends the fixed speed pack to 55°C and the VSD pack to 50°C, and the air-cooled VSD FF runs at temperatures up to 46°C / 115°F as standard.

Artículo completo: El secador de refrigerante integrado

In the GA 110 VSD Full Feature, the refrigeration dryer is fully integrated in the compressor unit. The all-in-one layout reduces the floor space needed for the compressor room and removes the piping installation work a standalone dryer requires. The typical pressure dew point of the refrigerant dryer is 3°C (37.4°F) at reference conditions, and the dew point is continuously monitored while the machine runs.

Control del ciclo de ahorro y separación de aceite

El exclusivo y patentado sistema «Save Cycle Control» detiene la secadora cada vez que el compresor se detiene o se encuentra en modo de descarga, lo que reduce el consumo energético del sistema de tratamiento de aire. En cuanto al sistema de aceite, el separador utiliza varios cartuchos más pequeños en lugar de un único tambor grande, lo que simplifica y acorta las tareas de mantenimiento y minimiza el arrastre de aceite hacia la corriente de aire.

Supervisión y control

The Elektronikon MK5 Touch controller runs the GA 110 VSD from one full-color touch display. Clear icons and intuitive navigation give fast access to all of the important settings and data, the controller monitors the running conditions and the maintenance status, and the built-in remote control and notification functions come with a simple integrated webpage as standard. Support covers 31 different languages, including character-based languages.

SMARTLINK y Optimizer 4.0

SMARTLINK monitors the compressed air installation over the ethernet: customized reports track the energy efficiency of the compressor room, components are replaced on time to keep uptime high, and early warnings avoid breakdowns and production loss. With the Elektronikon unit controller, a plant switches between two setpoints manually or automatically, and the sophisticated algorithm runs the drive motor only when needed while the desired setpoint is maintained.

Installations with several machines add Optimizer 4.0. It starts and stops compressors to minimize excess pressure, regulates the VSD so the output stays proportional to the demand, and adjusts the system pressure automatically to compensate for pressure drops caused by filters, piping and dryers. The result is the full energy saving potential of VSD across the whole compressor room instead of a single machine.

Applications of the GA 110 VSD

The GA 110 VSD fits plants whose air demand moves with the production program: machining halls that idle between batches, bottling and packing lines that run campaign production, and blow molding or conveying duties that breathe with the schedule. In these profiles the drive pays for itself twice over, first through the part load savings and second through the stable pressure band that protects the downstream consumers.

Metal plants use it for instrumentation, plant air and the pneumatic conveying of raw materials or ash, and power plants keep a continuous supply of compressed air for soot blowing and fly ash handling. Mining operations run the GA 110 VSD for dust bag filtration, service air, ventilation air and pneumatic tools, where reliability and robustness decide the shift plan. Cement works are among the biggest consumers of compressed air, and this is exactly where the IP66 drive train, the grouped service area and the slide out coolers of the platform earn their place.
