About This Service
Ali Hassan Marine’s compressor overhaul service goes beyond surface-level repairs. We perform structured, methodical overhauls that address internal wear, lubrication systems, seals, valves, and electrical components. Whether your compressor is showing signs of performance decline or has suffered a mechanical failure, our engineers restore it to full operational specification.

Compressor Overhaul Services We Provide
Pre-Overhaul Performance Assessment
Before disassembly, we record all operating parameters — pressures, temperatures, oil analysis, vibration, and energy consumption. This baseline guides the overhaul scope and documents improvements post-service.
Full Compressor Disassembly & Inspection
We disassemble the compressor completely, inspecting all internal components against manufacturer tolerances. Every part is assessed — not just those showing obvious wear.
Bearing & Seal Replacement
Bearings and shaft seals are wear items that degrade with time. We replace them with OEM-equivalent components to restore smooth, leak-free operation.
Valve & Piston Reconditioning
Reciprocating compressor valves and pistons are reconditioned or replaced to restore full compression efficiency. Worn valves are a major cause of reduced capacity and high energy consumption.
Lubrication System Service
Oil separators, oil pumps, and lubrication circuits are cleaned and serviced. Correct lubrication is critical to compressor longevity and efficient operation.
Electrical & Control System Check
Motor windings, contactors, and protection devices are tested. Electrical faults in the motor or control system are corrected during the overhaul.
Post-Overhaul Testing & Commissioning
After reassembly, the compressor is run through a structured test protocol under load. We verify all operating parameters before returning it to service.
Common Compressor Faults We Resolve
Compressor faults are among the most disruptive problems in any industrial cooling system, affecting overall performance and bringing operations to a halt. Whether caused by mechanical wear, lubrication failure, electrical faults, or refrigerant issues, our engineers diagnose and resolve the full range of compressor problems across UAE industrial and commercial facilities — restoring reliable operation quickly and minimising damage to connected equipment.
Low Compression Efficiency
Worn valves, worn piston rings, or internal leakage reduce compression ratio and cooling capacity. An overhaul restores design compression efficiency and energy performance.
Excessive Vibration & Noise
Worn bearings, loose components, or shaft misalignment cause abnormal vibration. We identify and resolve the root cause during the overhaul process.
Oil Contamination in Refrigerant Circuit
Degraded shaft seals or oil separator failure allows lubricant to migrate into the refrigerant circuit. This reduces heat transfer and damages downstream components. We address both the cause and the contamination.
Overheating Under Load
Blocked oil coolers, inadequate lubrication, or high discharge temperatures cause compressors to overheat. We restore lubrication performance and optimize heat rejection.
Why Compressor Overhaul Is Better Than Replacement
Compressor replacement is often unnecessary and far more expensive than a professional overhaul. In most cases, internal wear, valve damage, or lubrication failure can be fully resolved through precision reconditioning — restoring performance at a fraction of the replacement cost. Our engineers assess each unit thoroughly and recommend replacement only when the compressor is genuinely beyond economic repair.
Significantly Lower Cost
A well-executed overhaul costs a fraction of full compressor replacement. Where the compressor housing and motor are sound, overhaul is always the cost-effective choice.
Faster Return to Service
Replacement compressors — especially for industrial units — can have long lead times. An overhaul by experienced engineers is often faster than sourcing and installing a replacement.
Preserves System Compatibility
Replacing a compressor sometimes requires system modifications. Overhauling the existing unit maintains full system compatibility with no additional integration work.
Environmental Responsibility
Overhauling and reconditioning equipment reduces industrial waste and the environmental impact of manufacturing new components. It’s a sustainable choice for responsible operations.
Our Compressor Overhaul Process
Our compressor overhaul process begins with a complete strip-down and internal inspection, assessing valve condition, bearing wear, and lubrication integrity. Damaged components are reconditioned or replaced to manufacturer specifications, before the unit is reassembled, pressure tested, and recommissioned. Every overhauled compressor is returned to service fully verified — restoring cooling performance and extending equipment lifespan across UAE industrial facilities.
Fault Diagnosis & Scope Definition
We analyze fault history, operating data, and initial inspection findings to define the overhaul scope clearly. No unnecessary work — and no missed faults.
Controlled Disassembly
The compressor is disassembled under controlled conditions, with all components catalogued and measured against design tolerances. Clearances and wear rates are documented.
Component Reconditioning & Replacement
Worn or damaged components are reconditioned where possible or replaced with OEM-equivalent parts. All replaced items are documented for your maintenance records.
Reassembly, Testing & Commissioning
The compressor is reassembled to specification, then run through a full test protocol. Performance data is recorded and compared against pre-overhaul measurements to confirm the improvement.
We contacted them for our chiller units and split AC systems at our factory. Their team handled the compressor change professionally and completed the new split AC installations on schedule. Clean work, no mess left behind, and the systems have been running perfectly ever since. Highly dependable.
The team was mobilised quickly to our vessel MV Green Land. They carried out a full compressor overhaul and reinstallation in the ECR room and fitted the new 5-ton 60Hz AC units without any delays. Their understanding of marine electrical systems and refrigeration gave us full confidence. Excellent execution from start to finish.
They serviced all AC units aboard MV White Land, replaced the faulty compressor, and installed both 3-ton and 5-ton 60Hz units. The team worked efficiently within our port window and left the systems fully operational. We will continue working with them for future maintenance across our fleet.
They mobilised to MV AM Princess with a full team and tools. The entire refrigeration system was recovered, flushed, pressure-tested and vacuumed before recharging with R404A. The expansion valve, orifice, and drier cores were all replaced with new parts. The system passed pressure hold for a full hour before recharge. It's running in perfect condition now. Thorough, documented, and professional.
