The speed-controlled, screw compressors in the Alup ALLEGRO series have been specially developed according to the most recent findings in research and technology. They are for use in all situations where compressed air needs vary.
Market analyses show that on average capacity utilisation of compressors is around 50 - 70%. The maximum delivery quantity is only required at peak times.
This has prompted us to develop the ALUP SCD technology which demonstrates its greatest strength in the partial load range, i.e. exactly where it is required.
Intelligence, Innovation & Reliability are the watchwords of Alup® manufacturers of the Allegro system of variable speed rotary screw air compressors. This range is suited to heavy industries and is used many large blue chip companies where power and reliability within extreme conitions are of paramount importance. The Allegro range benefits from the latest techniques in research & development and are manufactured in accordance to ISO 9001 and CE guidelines.
The Allegro boasts;
• Constant net pressure - infinitely variable from 5 to 13 bar
• Elimination of high starting current and star delta change surge
• No expensive wasted energy for idle running
