Selecting the right single-shaft compressor requires matching process needs, site constraints, and maintenance strategy. Key considerations include required pressure and flow, duty cycles, part-load behavior, and accessibility.
When to choose vertically split casing
Best for compact, multi-stage installations where horizontal removal of the rotor assembly is preferred. Vertical split casings allow multiple process stages inside one casing and horizontal pull-out of the internals for major overhaul without disconnecting process piping—ideal when floor space is limited but lateral extraction is feasible and full-overhaul access is occasionally required.
When to choose horizontally split casing
Preferred for installations requiring independent per-stage designs (through-flow, back-to-back, split-flow), frequent inspections, or easy routine maintenance. Horizontal split casings permit opening the casing for inspection without moving the baseplate or separating piping, and they accommodate side-streams and interstage cooling while simplifying part-load efficiency optimization via inlet guide vanes.
Additional guidance
Select vertical for dense, overhaul-oriented layouts; select horizontal for operational flexibility, simpler routine access, and multi-configuration processes.
