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.
Why customers choose us
- Fixed-price overhaul quotes — no cost surprises during execution.
- All parts procured and staged before your shutdown window opens.
- Rotor balancing in-house to API 617 / ISO 1940 G2.5.
- Optional: controls retrofit and efficiency upgrades during the overhaul.
- 24/7 execution during shutdown periods.
Process
Assessment
Pre-shutdown survey — vibration baseline, performance test, scope definition.
Disassembly
Systematic strip with as-found documentation — dimensions, clearances, photos, NDT.
Rebuild
Component repair/replacement, rotor balancing, bearing installation, clearance verification.
Commissioning
Reassembly, alignment, startup, performance verification, and handover.
Frequently asked questions
How long does a complete overhaul take?+
Workshop overhaul: 6–10 weeks. On-site overhaul: 10–14 days during a planned shutdown. Expedited options available for emergency situations.
Can you overhaul a compressor that's 30+ years old?+
Routinely. We've overhauled machines from the 1970s. Obsolete parts are reverse-engineered. We often combine overhaul with selective upgrades (seals, controls) to extend the machine's useful life by 15–20 years.
What if you find additional work during disassembly?+
We photograph and document every finding. Any scope changes are discussed with you before proceeding — with pricing and timeline impact. No surprises.
Do you provide a performance guarantee?+
Yes. We guarantee the overhauled compressor meets its original design performance parameters at commissioning. If it doesn't, we fix it at our cost.
