We Buy & Sell Used, Refurbished & Scrap Generators & Portacabins Across UAE
The complete engineering and commercial guide to industrial diesel generator acquisition, scrap power plant dismantling, certified zero-hour refurbishment, modular site portacabin liquidation, and secondary equipment trading across Dubai, Abu Dhabi, Sharjah, and all seven Emirates.
1. UAE Commercial Buy & Sell Division: Used, Refurbished & Scrap Asset Liquidation
In the fast-moving industrial and construction landscape of the United Arab Emirates, equipment lifecycles move at an accelerated pace. Large civil construction ventures in Dubai conclude their multi-year projects, major oil and gas concessions in Abu Dhabi decommission remote desert camps, and manufacturing facilities in Sharjah upgrade their heavy electrical infrastructure. What happens to the heavy capital equipment left behind?
Rental Power UAE operates the region’s premier specialized Asset Trading and Industrial Buyback Division. We are active cash buyers and volume suppliers of:
- Used & Operational Portacabins: We buy second-hand modular office cabins, supervisor units, conference cabins, and labor welfare accommodation across all project sites.

2. Comprehensive Generator Trading: Buying & Selling Used, Refurbished & Scrap Diesel Gensets
Diesel generators represent the primary electrical lifeline for off-grid construction, quarrying, deep well dewatering, and continuous factory operations. As projects evolve, keeping idle generators on-site depreciates valuable capital, consumes yard space, and creates battery and oil leak hazards.
What Generators Do We Buy Across the UAE?
Our procurement division purchases industrial diesel generators in any operational condition, from single standby sets to multi-megawatt power stations:
- Operational Used Generators (Prime & Standby): Gently used units with 1,000 to 8,000 running hours that have served in commercial towers, private hospitals, shopping malls, or clean industrial facilities. We pay top fair-market value based on engine telemetry and maintenance records.
- Refurbished & Overhauled Units: Pre-owned generators that have undergone mid-life overhauls. We evaluate the quality of rebuild components, alternator rewinding, and digital control retrofits.
- Scrap & Condemned Generators (Dead / Seized / Flood-Damaged): Engines with thrown connecting rods, cracked cylinder liners, water-damaged alternators, or units retired after 25,000+ hours. We evaluate these units based on heavy cast-iron engine block weight, high-purity copper stator/rotor winding tonnage, and acoustic canopy steel scrap market indices.
Top Generator Engine Brands We Buy & Sell
We actively trade in the world's most reputable industrial diesel engine platforms:
- Caterpillar (Cat): 3406, 3412, C15, C18, 3512, 3516, and C32 heavy industrial diesel power modules.

The 50-Point Technical Refurbishment Protocol for Resale Gensets
Before any pre-owned generator is cleared for sale from our regional yards, it undergoes a comprehensive zero-hour engineering overhaul:
- Cylinder Block & Crankshaft Line Bore Audit: The engine is completely disassembled. Crankshaft journals are measured with digital micrometers and micro-polished. Main and con-rod bearings are replaced with genuine OEM shells.
- Cylinder Liner Re-Honing & Ring Replacement: Cylinder liners are inspected with borescopes for cross-hatch integrity and honed or replaced. New piston crowns, rings, and wrist pins are installed.
- 1000V DC Megger High-Voltage Alternator Testing: Stator and rotor windings are vacuum-pressure washed, dried in thermal ovens, and re-varnished with Class H dielectric insulation. We verify that phase-to-phase and phase-to-ground insulation resistance exceeds 10 Megohms, eliminating any risk of winding flashover.
- Digital Control Modernization: Obsolete analog gauge panels are stripped and retrofitted with genuine Deep Sea Electronics (DSE 7320 / DSE 8610) or ComAp digital synchronizing controllers with integrated AMF (Auto Mains Failure) and remote telemetry monitoring.
- Full Resistive Load Bank Certification: The rebuilt unit is connected to our mobile load banks and tested step-by-step for 4 continuous hours at 25%, 50%, 75%, 100%, and 110% overload. A stamped mechanical test certificate verifying frequency stability, oil pressure, and exhaust temperatures is delivered to the buyer.

7. Frequently Asked Questions (Used & Scrap Generator and Portacabin Trading)
How do you calculate the cash offer for our used or scrap generator?
For functional used generators, valuation is determined by engine make and model (e.g., Cat, Cummins, Perkins), verified running hours from the electronic control module (ECM), overall mechanical condition, presence of soundproof canopies, and secondary market demand. For scrap generators, valuation is calculated strictly on certified scrap metal weight—specifically heavy cast-iron engine blocks, steel enclosures, and high-purity copper windings from alternators.
Can you dismantle and remove multiple portacabins from our site simultaneously?
Yes. Rental Power UAE has the heavy logistics capacity to clear entire 50-cabin site compounds in a matter of days. We deploy tandem mobile cranes, cutting crews, and a continuous convoy of low-bed trailers to ensure full site demobilization before your land lease or project permit expires.
What testing do you perform on a refurbished generator before we take delivery?
Every refurbished generator undergoes our certified 50-point technical audit. This culminates in a continuous 4-hour resistive load bank test at 100% rated capacity and 1 hour at 110% overload. Alternators undergo 1000V DC Megger insulation resistance testing, and engine cylinders are inspected with digital borescopes. You receive a certified load bank test certificate and comprehensive workshop warranty.
Do we need to drain engine oil, coolant, or diesel fuel before you collect our equipment?
No. Our certified mechanical team brings specialized fluid evacuation suction pumps, containment barrels, and spill containment kits. We handle all fluid draining on-site in full compliance with local municipal environmental guidelines at zero cost to you.
What is the price difference between a scrap portacabin and a refurbished portacabin?
A scrap portacabin has rusted structural steel, water-rotted flooring, or delaminated sandwich panels, and is purchased at raw scrap metal salvage value. A refurbished portacabin has undergone complete structural sandblasting, anti-rust undercoating, installation of new 50mm–100mm PU sandwich panels, certified rewiring, commercial vinyl flooring, and brand-new split air conditioning—delivering a turnkey modular office ready for immediate client use at approximately 50% of the cost of a brand-new cabin.
Do you also purchase decommissioned chillers, air conditioners, and shipping containers?
Yes. Through our specialized asset recovery divisions, we actively buy decommissioned used industrial chillers, commercial packaged AC units via our used chiller & AC buyer services, 20ft/40ft shipping containers, and mobile accommodation caravans across Dubai, Abu Dhabi, and Sharjah.
