FS Elliott Centrifugal Compressors
Centrifugal air compressors also referred to as dynamic compressors, are designed to produce large volumes of compressed air in an extremely energy efficient process. Although manufacturers that require over 200 to 250 total horsepower tend to realize the greatest savings, all industrial manufacturers should consider the advantages of centrifugal technology.
Oil-Free Compressed Air StreamThe risk of trace oil reaching the finished product or oil contamination in equipment lines leading to higher maintenance and downtime is avoided with a centrifugal compressor. Condensate generated from a centrifugal compressor is not subject to the same local regulations as oil-contaminated condensate, allowing for easy and low-cost disposal.
Fewer Maintenance Requirements
Centrifugal compressors do not rely on wearing surfaces to create compression, leading to longer-lasting bearings and other rotating components. The number of extra components such as oil and filters are drastically reduced saving material and labor costs. FS-Elliott air compressors take maintenance-friendly operation a step further by offering a horizontally split gear case, allowing full access to the gearbox in the field and avoiding costly downtime.
Increased Energy Efficiency
Available in up to four stages, centrifugal air compressors are on average 5% more efficient than older compressor designs. As the number of stages increases, the compression ratio is lower, meaning higher efficiency.
How Does a Centrifugal Compressor Work?
Centrifugal compressors, also known as dynamic compressors, efficiently converts the energy utilizing a series of stages to compress and cool the air as it continuously flows through the unit. A centrifugal compressor imparts kinetic energy into the airstream by increasing the velocity of the air using a rotating element and then converts this kinetic energy into potential energy in the form of pressure. In between each stage of compression, the air is cooled, and excess moisture is removed to further increase the efficiency and air quality. This design results in the ability to produce large quantities of air efficiently in a relatively small package.
Due to the continuous flow through multiple stages, centrifugal compressors are designed to thrive in higher capacities and are best suited for applications above 200 total horsepower.
