Atlas Copco have developed their own inverter, named ‘NEOS’, which has been specifically designed to operate with their range of compressors.
Introducing three NEOS inverters, the following compressor models in production from 24/02/2014 will be fitted with the new NEOS drives: GA37VSD, GA45VSD, GA55VSD, GA75VSD and GA90VSD. All compressors built after February 2014 will be fitted with NEOS drives.
Why have Atlas Copco developed their own inverter?
- Simplicity. Standard inverters are designed to be universal for many applications and therefore include a lot of features and hardware components that may not required. Less parts, less parameters that can be set or changed, less things that have to be maintained - less things that can break down. Simplicity is key.
- Power. The majority of applications for standard inverters are for pumps and fan drives which are not ideal for constant torque requirements of a compressor. Compressors are rather special and much more demanding than the average pump or fan.
- Availability. NEOS is Atlas Copco’s own design and this helps better control the availability of spare parts, also having the opportunity to make the future generation drives completely interchangeable with current generations.
- Dust Protected. Standard drives have typically an IP20 protection degree and many failures can be attributed to the ingress of dust. This possibility has been designed out in the NEOS which has an IP protection degree of IP5X. “5” means dust protected - Ingress of dust is not entirely prevented, but it must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment; complete protection against contact. Hence the power electronics and interior parts of the drive are protected against dust. This was tested during the project.
