GA 11 – 30 (kw) Compressors

The Atlas Copco GA 11-30+ is a state-of-the-art air (or water cooled), silenced, rotary air compressor with extended monitoring capabilities. They are industry leading in free air delivery and specific energy requirement, setting the standard in the oil-injected rotary screw air compressor technology.

The compressor package includes a direct driven, superior rotary screw compression element, driven by a high efficient, totally enclosed fan cooled motor, an integrated lubrication and cooling system and an integrated oil/water separator built into a sound-insulated bodywork where noise levels are minimized. The silencing enclosure allows the possibility to have a workplace compressor next to the point of use, minimizing the installation costs and maximizing energy efficiency.

These compressors are equipped with the Atlas Copco Elektronikon® Graphic controller, to control and monitor the compressor in the most efficient and reliable way.

  • Description

    GA11-30+ Full Feature

    The GA 11-30+ Full Feature are additionally provided with an air dryer which removes moisture from the compressed air by cooling the air to near freezing point and automatically draining the condensate.

    5-11kw

    Designed for extreme running conditions

    The GA has been designed to operate continuously in the most extreme running conditions. All rotating components are totally enclosed and protected against contamination to ensure long and reliable operation. The compressor cooling system is sized to run perfectly in ambient temperatures up to 46°C/115°F and high ambient versions up to 55°C/131°F.

    5-11kw

    Superior efficiency ensuring lowest operating costs

    Designed to meet the highest levels of reliability, energy efficiency and air quality, the compressor package includes following main features:

    5-11kw

    • Comprehensive, pro-active maintenance display.
    • User-friendly, intuitive navigation system.

    Forced cooling of electrical cubicle

    All cubicles are equipped with an electrical cubicle fan, including a filter, ensures the optimal working temperature.

    • Extra filtration eliminates environment dust in the electrical cabinet, to increase the components lifetime.
    • Extra cooling of the cubicle keeps the temperature low, having the electrical components working in optimal temperatures.

  • Efficiency

    State-of-the-art rotary screw element

    Patented, in-house designed oil injected rotary screw elements with the latest Atlas Copco asymmetric rotor profile. Designed for the optimum combination of maximized free air delivery for the lowest power consumption.

    • Extended lifetime.
    • Precise oil injection for the highest performance at the lowest element temperatures and minimal losses.
    • Designed for low wear and tear, thanks to the selection of high quality materials.

    Most efficient transmission and drive system

    All compressors are equipped with a Y/D starter, to lower transmission losses and smooth starting.

    • IE3 Efficiency class (50Hz).
    • Maintenance free, eXtreme duty gearbox drive resulting in lower drive end bearing temperature and longer bearing lifetime.
    • Direct gear-driven high performing element eliminating coupling losses and maintenance.
    • TEFC, IP55 Leroy Somer motor enclosure.
    • Class F insulation, B temperature rise.

  • Quality

    Heavy duty air inlet filter

    To protect the compressor components from wear, even in the harshest environments, a heavy duty air inlet filter is integrated in the package, ensuring:

    • Long lifetime of internal components.
    • Two steps of dust removal.
    • Premium filtration of particles > 3µm with an efficiency of 99.9%.
    • Long service intervals.
    • Equipped with differential pressure service indicator as standard.

    Protecting your production process

    The integrated high efficient cooling system with air/oil separator ensures a low residual oil content in the, free of liquid condensate, compressed air.

    • Separate oil- and after cooler, to optimize the cooling for both media, resulting in low air outlet temperatures and less oil carry-over.
    • EWD330M no-loss drain installed as standard to remove condensate (no corrosion due to free condensate) effectively without wasting compressed air.

    Minimized installation work

    The compressor packages are completely pre-wired and assembled to minimize the installation work onsite.

    • Minimized Installation.
    • Easy ducting installation due to cool canopy concept (single cooling air inlet/outlet location).
    • Integrated refrigerant dryer (FF compressors), mechanically and electrically connected (no extra power supply required).

  • Working principle

    Working principle

    The air is drawn into the compressor through the inlet filter (1) and is compressed in the oil injected rotary screw compression element (3) via the air intake (load-unload) valve (2).

     

    Lubrication fluid is injected into the air and the air / oil mixture passes through a non-return valve (4) to the oil separator element (5).

     

    The air then passes through a minimum pressure valve (6) and is cooled by an air- or water cooled after cooler (7).

     

    The condensed moisture is removed by an integrated low pressure drop moisture separator and electronic condensate drain (9) and the compressed air is released to the main piping.

     

    Lubrication fluid contained in the oil receiver (5) flows under differential pressure to a thermostatic bypass valve (13), air or water cooled oil cooler (12), high efficiency oil filter (14) and oil stop valve (15) before being injected into the compression element (3) where it cools, seals and lubricates the compression process.

    working-principle

    The high efficiency oil filter (14) provides superior filtration compared to conventional filters resulting in cleaner lubricant. The thermostatic bypass valve (13) ensures that the compressor quickly reaches optimum operating temperature on start-up and maintains temperature during periods of low load by allowing cold lubricant to bypass the oil cooler.

     

    A low noise radial cooling fan (for air cooled compressors) provides cooling air to the oil cooler (12) and after cooler (7), ensuring satisfactory running temperatures as well as ventilating the compressor enclosure.
