Screw compressor Atlas Copco GA30VSD+ 7Bar

Screw compressor Atlas Copco GA30VSD+ 7Bar

Atlas Copco's new transformation

Atlas Copco's GA7-110VSD+ series compressors use variable frequency drive technology and are equipped with an embedded permanent 

magnet motor (IPM). They are compact in structure, small in footprint, and have an average energy saving of up to 50%. Their advanced design 

ensures long-term stable operation of the machine and greatly reduces the cycle cost. This performance has won wide attention and recognition 

in the compressor industry.

GA 7-37 VSD+ series innovation from inside to outside

Permanent magnet (IPM) motor

•Oil-cooled motor, with an efficiency level close to or equivalent to the IE5 standard

•Specially designed oil cooling method makes cooling more efficient

•Independent design from Belgium

•Motor protection level IP66, significantly better than IP55

•Oil-cooled motor, no cooling fan required

•Motor bearing oil lubrication, ultra-long operating life

Rotor

•Special rotor profile design, low pressure loss

•Reliable, efficient and quiet

Direct drive

•Vertical design, few parts

•Oil cooling, pressure sealing

•No transmission loss, high efficiency

•Compact: footprint reduced by about 60%*

New fan

•Innovative axial fan design, low noise level

Oil filter/separator

•Integrated design of oil filter, oil separator and thermostatic valve

•Simple and convenient maintenance

Electronic drain valve (manual and automatic)

•Standard supply

•Under normal operation, condensate can be automatically discharged, and compressed air has zero loss

•When the power is off, condensate can be manually discharged through the integrated bypass valve

Elektronikon® touch screen controller

•Built-in intelligent algorithm to optimize system pressure and reduce overall energy consumption

•Remote control, alarm output, maintenance plan, network diagnosis are all available

• Built-in Smartlink remote monitoring to understand the system status at all times

Intake valve

•Smooth intake, no air stagnation

•Small intake pressure drop

•Maintenance-free

VSD+ electric control box

•VSD+ series electric control box adopts forced cooling to dissipate heat

•Electronic components are kept well cooled, extending the effective working time of components

•Specially designed for IPM permanent magnet motors

•Standard DC variable frequency reactor

•Inverter is placed independently, with good heat dissipation and no compression heat
