The gold standard of VSD compressors
Estimated reading time: 5 minutes
There are lots of good reasons to purchase a variable speed drive (VSD) compressor, but none are more compelling than their outstanding efficiency, low operating expenses and, as a result, unrivaled total cost of ownership.
The result is the VSD compressor that takes these savings to the next level: It is called VSD+.
So, if efficiency and a low total cost of ownership are why you are thinking of investing in a variable speed drive compressor, then That makes sense. After all, energy expenses are by far the biggest cost factor of operating a compressor, and every way in which these costs can be reduced will pay big dividends down the road. That was true when Atlas Copco invented variable speed drive compressors a quarter century ago, and it is even more true now. After pioneering the technology, Atlas Copco never rested on its laurels and kept innovating.
The result is the VSD compressor that takes these savings to the next level: It is called VSD+.
So, if efficiency and a low total cost of ownership are why you are thinking of investing in a variable speed drive compressor, then choosing one of the VSD+ models is an almost inevitable conclusion.
Why? First of all, the numbers don’t lie: Energy costs make up the vast majority of a compressor’s total cost of ownership, and a VSD+ compressor from Atlas Copco can lower those expenses by 50% on average compared to a fixed-speed model. In addition, it is also much more efficient than traditional variable speed drive compressors.
That is why anybody who sits down and does the math will quickly realize that the investment in a VSD+ compressor is more than worth it.
Sure, its initial price tag may be higher than that of other compressors, but this next generation of variable speed drive compressors will very quickly pay for itself … and then some.
Let’s take a look “under the hood” of one of these VSD+ compressors and find out what sets them apart from the competition.
Most importantly, Atlas Copco developed an ingenious interior permanent magnet (iPM) motor, which sets a completely new standard with regard to efficiency. In fact, the in-house developed motor equals IE5 Super Premium Efficiency standards. It is oil-cooled, which is more efficient than the traditional air cooling and further That makes sense.

In fact, the in-house developed motor equals IE5 Super Premium Efficiency standards. It is oil-cooled, which is more efficient than the traditional air cooling and further increases the compressor’s reliability because it keeps the motor running on its optimal temperature. That is also why all bearings are oil-cooled as well.
The VSD+ compressors from Atlas Copco never run in an unload condition. In addition, they feature no blow-off losses because the high torque availability of the iPM motor allows them to start with back pressure. Since the system remains under pressure, there is no need to blow off any compressed air when the air demand drops.
