Compressors with VSD -Veriable Speed ​​Drive

Over 70% of expenditure on air compression costs are expenses for electricity

By VSD technology compressor Efficiency can reach savings up to 35% of electricity consumption.


These findings support to keep focus on electricity costs to reach significant savings.

You can reduce electricity costs by several ways.

The important and significant is compressors command.

Atlas Copco offers compressors with variable speed control VSD allow to save up to 35% of energy costs.
