How to cut the energy consumption of compressed
FPS Air Compressors can provide a number of tips and initiatives to reduce the energy consumed by compressed air systems. In particular, the company offers the new NOBEL PM series of oil-injected rotary screw compressors, which feature IE4 permanent magnet motors, variable speed drives and an extended airflow range for the highest level of energy efficiency and quiet operation. This industry-leading performance helps to counter the current trend of spiralling energy costs, which look likely to remain high for the foreseeable future. Compared with the operating costs of a standard compressor. As an example, a user operating a 37 kW Nobel DVPM air compressor can enjoy savings of up to £25,000 a year or more.
There are three principal compressor metrics to consider: specific energy; greater FAD (free air delivery) performance; and a wider operating range to suit varying demand.
The specific energy value reveals how much power (kW) is used to generate a specific volume of compressed air (1m³). Users unfortunately often overlook this highly accurate measure of an air compressor’s energy efficiency. However, NOBEL PM series models from Power System deliver a 3-8% better specific energy performance in comparison with competitor alternatives.
Regarding the second metric, the maximum available capacity is important because a compressor with better FAD performance is able to cope with peaks in demand that would otherwise require an additional or even larger, higher energy consuming compressor. NOBEL PM models provide extremely high maximum capacity figures compared with competitors. For example, the 22kW NOBEL 24 DVPM has an FAD performance delivering over 4500 l/min, which is almost 10% better than industry peers.
The third metric considers the operating range of a variable-speed compressor. This factor is important in satisfying the fluctuating demands of production and in preventing the air compressor from entering an ‘idle’ state, which is extremely wasteful in energy. To avoid this situation, NOBEL DVPM models operate with a wide range of between 15% and 100% of available capacity.
These advanced technologies, alongside the use of latest-generation air-end units, has facilitated the creation of the most innovative and reliable compressor available.
