Centrifugal Air and Gas Compressors for Air Separation
Compression represents a significant energy demand in air separation, making efficiency a priority for controlling production costs. Air systems must deliver the required flow and pressure consistently while accommodating changes in demand without unnecessary power consumption.
Air quality and equipment availability are equally critical. Contaminants can compromise downstream equipment and gas purity, while an interruption in compressed air supply can disrupt production. Operators need dependable, oil-free compression with practical maintenance access to support continuous operation.
FS-Elliott works with plant owners, process suppliers, and engineering teams to develop centrifugal compressor packages around the needs of each project. Our approach brings together compressor selection, package configuration, and controls to address process requirements and installation constraints.
From individual compressor duties to coordinated package arrangements, we help your team evaluate performance, integration, and service needs early in the project. The result is a compression solution designed with both initial installation and long-term operation in mind.
Maintain process purity and protect critical air separation equipment with ISO 8573-1 Class 0 oil-free compressed air. Our centrifugal compressors eliminate the risk of hydrocarbon carryover into downstream purification and cryogenic equipment while delivering the clean, dependable air required for continuous ASU operation.
Backed by more than 60 years of centrifugal compressor expertise, FS-Elliott combines proven aerodynamic design with advanced Regulus® control systems for dependable, energy-efficient ASU operation. R2000 and R3000 control panels provide continuous efficiency monitoring and maintenance planning, while advanced R3000 capabilities support precise process control, surge avoidance, ambient compensation, system redundancy, and critical ASU requirements.
FS-Connect® remote monitoring further helps maximize uptime and maintain reliable performance throughout the compressor lifecycle.
FS-Elliott offers flexible compressor configurations engineered for the critical performance and efficiency demands of air separation applications.
With solutions for Main Air Compressors (MAC), Booster Air Compressors (BAC), Booster Nitrogen Compressors (BNC), Nitrogen Gas Compressors (GAN), and combination units, multiple pressure, flow, control, and system options allow each compressor to be optimized for site-specific operating conditions, energy efficiency, and reliable long-term integration into the ASU process.
From installation and routine maintenance to parts, service, and remote monitoring, FS-Elliott provides comprehensive support throughout the life of your compressor. Our global service network and factory-trained experts help maximize uptime, maintain performance, and extend equipment life.
A commonly overlooked factor behind compressor performance is the influence of on-site conditions and the impact they can have on compressor design, daily operation, and running costs. These factors can directly affect energy consumption, daily operations, and system efficiencies, which are critical metrics for facility operators.
Compressed nitrogen and compressed air both power critical industrial systems, but their different physical and chemical properties lead to important distinctions in compressor design, safety, and packaging.
Combination or dual process machines can combine any two gases, with air and nitrogen being the most common for centrifugal compressors. These versatile compressors are used in various applications where both compressed air and nitrogen are required, such as manufacturing, food processing, aerospace, and electronics. The primary purpose of a dual-process compressor is to provide both compressed air and nitrogen, making it a cost-effective and efficient solution for many businesses.
