Bring your compressor back to day-one performance.
Complete strip, inspect, rebuild, and test — every component evaluated, every clearance verified, every bearing re-established. Your compressor returns to you performing like it did on commissioning day.
Problems you might be facing
Performance degradation over years of operation
Your compressor can't hold design pressure anymore — it's consuming more power for less output. Efficiency has dropped 10–20%.
Turnaround window is tight
You have a 2-week shutdown window and need the overhaul completed on time, on budget, with no surprises.
OEM wants to replace the entire machine
The OEM quotes a new compressor for $1–2M when a $200K overhaul would restore full performance.
Capabilities
Full mechanical overhaul
Strip, inspect, refurbish, and reassemble — all rotating and stationary components to OEM clearances.
Rotor rebuilding
Impeller refurbishment, shaft repair, new labyrinth seals, and dynamic balancing to API 617.
Performance testing
ASME PTC-10 style performance verification — confirming pressure ratio, flow, and power at design conditions.
Bearing & seal replacement
New journal bearings, thrust pads, carbon ring seals, and mechanical seals — complete rotating element refresh.
On-site or workshop
Workshop overhaul at our facility, or on-site overhaul at your plant — whichever minimizes downtime.
Complete documentation
As-found / as-left clearance sheets, NDT reports, balance reports, photos, and torque records — every detail recorded.
