1. Equipment Accepted: Diesel Generators from 20 kVA to 2,500 kVA
We purchase diesel power assets across all physical conditions, ages, and configurations throughout the United Arab Emirates:
Operational Low-Hour Standby Generators
Standby units retired from bank headquarters, data centers, government hospitals, and luxury towers with low lifetime running hours (under 2,500 hours). We evaluate complete maintenance logs, OEM service history, and pristine alternator condition to offer premium machinery asset prices.
Mid-Hour Construction & Rental Fleet Decommissioning
Heavy-duty soundproof containerized generators (100 kVA to 1,500 kVA) completing major infrastructure projects. We purchase entire contractor fleets at once, eliminating holding costs, yard storage fees, and depreciating book values.
Non-Functional, Seized & High-Hour Prime Sets
Generators with thrown connecting rods, cracked engine blocks, spun crankshaft bearings, or burnt alternator stator windings. These units are brought to our workshop for comprehensive mechanical rebuilding or component harvesting.
Total Loss & Scrap Metal Industrial Recycling
Units heavily oxidized from marine coastal exposure, fire damaged, or submerged in floodwater. We pay maximum scrap commodity value based on heavy electrolytic copper windings, cast-iron engine blocks, and high-gauge acoustic enclosure steel.
2. Commercial Valuation Methodology: Working Machinery vs. Scrap Metal
Our valuation framework is transparent, mathematical, and grounded in current secondary machinery market indices and London Metal Exchange (LME) spot rates:
| Generator Classification | Technical Condition Criteria | Valuation Driver & Multiplier | Payment Standard |
|---|---|---|---|
| Tier-1 Standby (Pristine) | Under 1,500 hours • Full OEM history • No blowby | 50% to 70% of current OEM replacement value | Instant Advance Bank Transfer |

3. Metallurgy & Material Breakdown: Scrap Generator Metal Recovery Yields
When a generator set has suffered catastrophic engine failure or fire damage rendering mechanical overhaul economically unviable, AMC assesses the unit strictly on recovered non-ferrous and ferrous metallurgical commodities. Unlike generic scrap yard operators who offer arbitrary flat rates, AMC calculates precise raw metal weights based on manufacturer engineering blueprints:
| Generator Rating | Electrolytic Copper (Stator/Rotor) | Radiator Core (Cu / Al Alloy) | Engine Cast Iron (Block/Head) | Heavy Structural Steel (Frame/Canopy) |
|---|---|---|---|---|
| 60 kVA (Perkins 1104) | 55 – 70 kg | 25 – 35 kg | 380 – 450 kg | 600 – 800 kg |
| 250 kVA (Cummins 6LTAA) | 160 – 210 kg | 65 – 90 kg | 950 – 1,200 kg | 1,400 – 1,800 kg |
| 500 kVA (Cat C15 / Volvo) | 280 – 360 kg | 110 – 160 kg | 1,700 – 2,100 kg | 2,200 – 2,800 kg |
| 1,000 kVA (Cummins KTA38) | 550 – 720 kg | 220 – 310 kg | 3,800 – 4,400 kg | 3,500 – 4,500 kg |
| 1,500 – 2,000 kVA (Cat 3516 / QSK60) | 1,100 – 1,450 kg | 420 – 580 kg | 7,200 – 8,800 kg | 5,500 – 7,000 kg |
By analyzing these material parameters alongside real-time London Metal Exchange (LME) spot cash settlement rates for high-purity Grade A copper cathode and UAE domestic heavy melting steel (HMS 1 and HMS 2) scrap indexes, AMC consistently delivers scrap payouts 20 to 35 percent above standard scrap yard quotations.
4. On-Site Technical Inspection: Fluke Megger & Load Bank Protocols
Unlike informal scrap dealers who guess machine condition, AMC deploys certified senior electrical and diesel engineers to conduct non-invasive technical health audits:
Alternator Insulation Resistance (Megger 1000V DC)
Phase-to-Phase & Phase-to-Ground Dielectric Proofing
We test phase-to-phase and phase-to-ground stator and rotor winding insulation impedance using calibrated Fluke 1587 insulation multimeters. Insulation resistance exceeding 100 Megohms certifies alternator health, preventing costly coil rewinds.
Crankcase Blowby & Cylinder Compression Testing
Digital Manometer Delta-P & Ring Sealing Efficiency
By measuring crankcase pressure with digital water manometers and inspecting the crankcase breather tube during running operation, we immediately determine piston ring sealing efficiency and cylinder liner wear without dismantling the engine.
Mobile Resistive Load Bank Step-Testing
Stepped 4-Hour ISO 8528 Thermal Saturation Proofing
For multi-megawatt generator purchases, we dispatch our trailer-mounted Avtron resistive load banks to test generators at 25%, 50%, 75%, and 100% full prime load for 2 to 4 continuous hours, verifying cooling radiator capacity, oil temperature stabilization, and AVR voltage regulation.
5. Step-by-Step ISO 8528-5 Resistive Load Bank Acceptance Protocol
Every operational used generator evaluated or certified for resale by AMC undergoes a structured 4-hour dynamic resistive load bank certification protocol conforming to ISO 8528 Class G2/G3 standards:
| Test Stage | Applied Load | Test Duration | Key Parameters Verified | Pass/Fail Acceptance Criteria |
|---|---|---|---|---|
| Stage 1: Thermal Warm-Up | 25% Nameplate kW | 30 Minutes | Coolant temp rise, thermostat opening, oil pressure build-up | Oil pressure > 3.0 Bar; coolant reaches 78°C |
| Stage 2: Intermediate Load | 50% Nameplate kW | 45 Minutes | Governor speed droop, exhaust gas temp across manifold branches | Frequency variation ± 0.5 Hz; EGT variation < 35°C |
| Stage 3: Full Continuous Prime | 75% to 100% kW | 120 Minutes | Radiator delta-T, alternator winding heat dissipation, AVR stability | Coolant < 98°C @ 50°C ambient; zero voltage hunting |
| Stage 4: Transient Overload | 110% Overload kW | 15 Minutes | Instantaneous 100% block load step rejection and recovery speed | Frequency recovery < 2.5 seconds; zero thermal trip |
During the 4-hour test run, calibrated digital logging instruments record three-phase voltage, current, active power (kW), reactive power (kVAR), power factor, frequency (Hz), oil pressure (PSI), jacket water temperature, exhaust pyrometer levels, and FLIR infrared thermography scans across main copper circuit breaker busbar terminations.
6. The AMC Generator Remanufacturing & Certified Overhaul Scope
Used generators acquired by AMC Generators that qualify for re-sale enter our specialized central workshop in Dubai, undergoing complete factory-standard remanufacturing:
Cylinder Head & Valvetrain Machining
Cylinder heads are hydrostatic pressure-tested to 5.0 Bar to detect microscopic thermal cracks. Valve guides, valve seats, and stem seals are replaced with genuine OEM components. Heads are surface-machined flat to factory tolerances to eliminate head gasket failure under extreme 50°C ambient loads.
Fuel Injection Pump & Injector Calibration
Mechanical PT (Cummins) and common-rail fuel injection pumps are disassembled and tested on Bosch automated calibration benches. Common-rail injectors receive fresh micro-nozzles, needle valves, and pressure pop-off springs, restoring precise atomization spray patterns and eliminating exhaust smoking.
Alternator Stator VPI Re-Varnishing
Alternator stators and rotors are chemically degreased, baked in drying ovens at 130°C to drive out moisture, and submerged in Vacuum Pressure Impregnation (VPI) Class-H insulating varnish tanks. This seals copper windings against high Middle Eastern atmospheric humidity and airborne salt mist.
Deep Sea Controller Modernization
Obsolete analogue gauge panels are upgraded to modern Deep Sea Electronics digital modules (DSE 7320 MKII / DSE 8610 MKII). This provides full Auto-Mains Failure (AMF) utility monitoring, RS485 Modbus telemetry, and automatic engine shutdown protection against overspeed, low oil pressure, and high coolant temperature.
7. Turnkey Rigging & Site Extraction Standard Operating Procedure
Removing multi-ton diesel generators from high-rise rooftops, basements, or live industrial substations requires strict adherence to safety protocols:
1 Electrical Lock-Out / Tag-Out (LOTO) & Utility Isolation
Certified electrical technicians physically disconnect generator busbar connections, isolate Automatic Transfer Switches (ATS), tag main circuit breakers, and safely coil heavy armored power feeds to prevent electrical hazards.
2 Diesel Fuel & Lube Oil Environmental Evacuation
All remaining diesel fuel in the sub-base tank is pumped into mobile bowsers, and engine lubrication oil and radiator coolant are drained into sealed UN-certified drums, completely eliminating road spill hazards during transport.
3 Mobile Crane Rigging & Transport
AMC provides heavy all-terrain mobile cranes (50-ton to 200-ton capacity) and low-bed trailers. Certified riggers attach load-tested wire rope slings to factory lifting points, smoothly hoisting the generator onto our transport trucks with zero damage to site curbs or pavements.
8. Competitor Benchmarking: AMC Generators vs. Street Scrap Dealers
