Inspection, rebuild and recommission
Compressor Overhauling
Full overhaul of reciprocating, screw and centrifugal compressors: stripped, inspected, measured against tolerance, rebuilt and proven on test before it goes back.

How we approach it
An overhaul is a measurement exercise before it is a mechanical one. Everything comes apart, every wearing surface is measured against the manufacturer's tolerance, and the decision to reuse, machine or replace each component follows from that measurement rather than from appearance.
You get the inspection report before the rebuild, with the replace or reuse recommendation for each item and what it costs. No parts are fitted on assumption, and nothing is replaced that measured good.
Rebuilt units are run and proven before dispatch, with capacity, discharge temperature, vibration and oil pressure recorded against the expected figures.

What we can build to
These ranges cover most of what we make. Duties outside them are reviewed case by case rather than refused on principle.
| Types | Reciprocating, screw, centrifugal |
|---|---|
| Scope | Strip, inspect, measure, rebuild, test |
| Inspection | Dimensional check against manufacturer tolerance |
| Typical replacements | Bearings, seals, valves, gaskets, rings |
| Testing | Run test with vibration and temperature recorded |
| Reporting | Written inspection report issued before rebuild |
Indicative figures. Final specification is confirmed against your duty and a site survey at quotation.
Standards and testing
- Rebuilt to manufacturer clearances and torque specification
- Vibration recorded at test
- Inspection findings documented and issued
How the work runs
The same sequence every time, so you know what happens next and what is expected of you at each stage.
Step 1
Removal and strip
Unit isolated, removed where required, and completely disassembled. Components cleaned so they can actually be inspected.
Step 2
Inspection and measurement
Every wearing surface measured against tolerance. Findings written up with a reuse, machine or replace recommendation and a cost for each.
Step 3
Approval
You approve the parts list before anything is ordered or fitted. No surprises at invoice stage.
Step 4
Rebuild
Reassembly to manufacturer clearances, with torque values and settings recorded as it goes together.
Step 5
Test and recommission
Run tested, then reinstalled and recommissioned on site with operating parameters logged against expected values.

Asked before you ask
Straight answers to the questions we hear most on this service line.
Overhaul or replace?
The inspection report answers that honestly. Where the casing and rotating assembly are sound, an overhaul restores performance for a fraction of the replacement cost. Where they are not, we say so. A rebuilt compressor that fails in a year serves nobody.
Can you work on a make you have not seen before?
Generally, yes, provided documentation and parts are obtainable. Where we cannot get the clearances or the parts, we tell you at enquiry rather than discovering it with the machine in pieces.
How long will the unit be out of service?
That depends on parts availability more than workshop time. Where downtime is critical, raise it at enquiry: pre-ordering the likely wear parts against the inspection shortens the turnaround considerably.
