Buying a Used 66 kVA Diesel Generator: What to Check Before Export

Why the 66 kVA Class Is a Common Choice

A 66 kVA standby diesel generator sits in a range that works for a single building or a mid-sized installation rather than a critical multi-megawatt site. Typical users include rental companies needing a fleet unit, contractors powering tools and site lighting, workshops and small industrial facilities, agricultural operations with irrigation pumps, and temporary power for events or exhibitions.

This specific set delivers 66 kVA standby (59 kVA prime) at 480 V, 50 Hz, three-phase, which matches the standard supply found across much of the Middle East, North Africa, South America and parts of Europe and Asia.

The Engine and Alternator Combination

The set is built around the Perkins 1103A-33TG1, a water-cooled three-cylinder diesel engine with a radiator and mechanical fan, electric starter, charge alternator, starting battery on a rack with cables, engine coolant heater, block heater and a protective grille. Heating is important in cold climates and for units that sit idle between rental periods.

The alternator is a Mecc Alte ECP machine, coupled to the engine with anti-vibration isolators on a base frame with an integral fuel tank.

Operating Hours and Year: Reading the Numbers

Two figures matter most when buying used equipment: the year of build and the recorded operating hours.

This generator was built in 1997 with 374 operating hours recorded. That is a very low figure for a machine of this age, and it suggests either light duty, limited deployment, or that the running hours have not been fully recorded. Buyers should treat the meter reading as an indication and confirm what the engine hour counter shows during inspection.

Older does not automatically mean unserviceable. What matters is condition, and that is why a genset should be test-run under load before it is paid for and shipped.

The Silent Enclosure and Control Panel

The unit is supplied in a silent canopy, which reduces noise for event, hospitality and urban site applications where sound limits apply.

Control is handled by a Datakom D200 module, with a static battery charger included in the equipment list. That gives automatic start, monitoring of key parameters and alarm functions — the sort of package a rental fleet or facility operator can work with, and one that is far easier to integrate than a basic manual panel.

Fuel Tank and Consumption

The base frame carries an 80 L integral fuel tank. Consumption is rated at 9.9 L/h at 75% prime load, which is the figure planners normally use for refuelling intervals and tank sizing. At the prime rating of 59 kVA the set covers the continuous loads of workshops, pumps and construction equipment without being asked to sit permanently on standby duty.

Logistics, Weight and Sizing

Weight is 750 kg, with dimensions of 2102 x 1026 x 1290 mm. These figures matter for delivery: the unit needs an appropriate lifting arrangement, and it must fit through the access route to its final position. Plan the pick-up point, doorway widths and floor loading before the shipment arrives.

What Export Buyers Should Confirm

Before committing to a used genset, ask the supplier to confirm:

• That the machine has been started and load-tested, and what the readings showed
• The engine condition and the state of the cooling and heating systems
• The alternator insulation condition and brush or bearing wear
• The condition of the control panel, battery and charger
• Battery, coolant and oil service history, and what the next service interval will be
• That the hour meter reading is genuine and matches the paperwork
• Which documents will accompany the shipment

Why Workshop Testing Matters

A genset that has been standing for years can hold fuel, oil and coolant levels, battery charge and coolant condition that a simple visual check will not reveal. Testing under load in a workshop before loading exposes faults while the machine is still on the supplier's site, not after it has crossed an ocean.

Every unit offered by Generator Export Center is checked in our own workshop before delivery. We handle loading, shipping by road, sea or air, and all export documentation, and each machine is assigned a personal advisor to follow the order from inspection to arrival.

Conclusion

A 66 kVA used set from 1997 with 374 hours, a Perkins 1103A-33TG1 engine, Mecc Alte ECP alternator, Datakom D200 control and a silent canopy is a workable option for contractors, rental fleets, agriculture and temporary power projects — provided it is inspected and load-tested before dispatch. Ask for the test results, request the full specification and arrange delivery through a team that manages the export paperwork end to end.
