Businesses with processes which rely heavily on supplies of compressed air don’t always need the same rate of flow or same pressure from week to week or month to month. As activity ebbs and flows throughout the production process or business cycle and different tools enter and leave the main ring, requirements for compressed air fluctuate. Such environments are where the variable speed compressor comes into its own.
Variable speed rotary screw compressors allow the selection of airflow rate and pressure across a wide range of values and can also be programmed to automatically regulate airflow to ensure consistency of delivery. This not only leads to greater efficiency but also significant savings on electricity. After all, why waste energy powering a compressor that delivers too much air?
Variable Speed Compressor Technology
Variable speed compressors utilise variable speed drives which control the number of revolutions per minute of the motor through AC/DC conversion using an inverter switching circuit. What this means in layman’s terms is that the compressor only delivers as much air as is needed and minimises inconsistent airflow patterns (e.g. surges and ebbs) caused by AC only motors.
Increase Efficiency with VSD Compressors
The supply of compressed air typically accounts for around a fifth of a factory’s electricity spend. This enhanced level control has the huge benefit of reducing unnecessary expenditure on surplus air when the production process is running at less than maximum capacity.
