VSD explained AtlasCopco

Vertical design

With the vertical design the customer can save up to 55% of the footprint of the traditional air compressors. This is a great benefit for customers that have tight installations or press for space in their facilities.

Oiled cooled motor

The purpose of the two different compartments is to keep all the components that produce heat in one area, separate from all the components that require cooling from the other. We are able to achieve this with the oiled cooled motor.

Biomimicry to reduce noise to only 62 dBA

The silent fan is inspired by nature: the owl. With its special wings, the owl can fly through the air very silently. This is the same benefit that we gain from this fan. The sound of the VSD+ compressor ranges between 62 and 64 dBA, which is as quiet, if not more quiet than most dishwashers.

The drivetrain

The magic is in the drive train, the combination of motor and element. Variable Speed Drive technology works best with rotary screw compressors, as their flow rate and their power consumption are virtually proportional to their speed. So as the motor adapts its speed, so do the screw elements and as a result, the amount of compressed air delivered. The electric motor is specifically designed for the job, with special attention to cooling requirements and efficiency across the entire speed range.

The motor

The motors in standard VSD units are induction motors, coupled to the screw elements with gears, but our VSD+ features an interior permanent magnet motor, a revolutionary in-house design. The motor shares a rotor with the screw elements, so it’s direct-driven, exceptionally quiet and most of all, very energy-efficient. The whole drive train of the VSD+ is a closed circuit, where both motor and elements are cooled with oil, another great way to save energy.

The brain

The motor speed of a VSD is kept in check by a frequency inverter and the on-board controller, the Elektronikon®, electronics that measure the system pressure and adjust the motor speed to the actual air demand.
