What to Check Before Buying Old Generators for Sale in Delhi NCR | Jain Generator Buying an old or second-hand generator can be a smart investment—especially for homes, shops, offices, small industries, and commercial establishments in Delhi NCR. Power cuts are still common in many parts of the region, and having a reliable generator ensures uninterrupted operations.
However, not all used generators offer the same value. To avoid breakdowns, repair costs, or low performance, it’s important to know what to check before buying an old generator in Delhi NCR. This detailed guide will help you make an informed and safe purchase.
1. Check the Generator's Age and Usage Hours A generator’s manufacturing year and running hours tell you a lot about its remaining lifespan.
A well-maintained generator with fewer running hours lasts longer Generators above 10–12 years old may require more frequent repairs Industrial generators with heavy usage may have more wear and tear
Tip: Check the hour meter, service records, and engine condition.
2. Inspect the Engine Condition Thoroughly The engine is the heart of the generator. Look for:
Smooth startup No unusual smoke (blue, black, or white smoke indicates problems) Steady engine sound without vibration No oil leakage Clean air filters and fuel filters
Suppliers like Jain Generator inspect engines thoroughly before selling refurbished generators, ensuring reliable performance.
3. Verify the Load Capacity Always choose a generator according to the load requirement of your:
Home Office Showroom Restaurant Factory Commercial setup
Common capacities include 5 kVA, 10 kVA, 20 kVA, 30 kVA, 62.5 kVA, 125 kVA, 250 kVA, and above. Make sure the generator still delivers full load output without drops, overheating, or fluctuating voltage.
4. Evaluate the Fuel Type and Efficiency Old generators available in Delhi NCR usually include:
Diesel generators (most common) Gas generators Petrol generators
Diesel generators are preferred due to durability and fuel efficiency. Check:
Fuel consumption rate Condition of the fuel tank Leakage signs Injector performance
5. Check for Noise Level and Pollution Compliance Delhi NCR has strict pollution and noise regulations. Ensure the generator meets:
CPCB norms Silent canopy installation Proper exhaust system
A non-compliant generator may lead to penalties.
6. Inspect Alternator & Electrical Components Before buying, check:
Alternator output Wiring condition Insulation quality AVR (Automatic Voltage Regulator) Battery condition Control panel functionality
Any damaged electrical part can lead to costly repairs.
7. Review Maintenance History A well-maintained generator always performs better. Ask the seller for:
Service logs Past repair details Oil change records Replacement parts history
Suppliers like Jain Generator provide complete maintenance documentation for transparency.
8. Test the Generator Under Load Before Purchase Before finalizing, run the generator with actual load and observe:
Start-up time
Load handling capability Noise and vibration Fuel consumption Output stability
A real-load test is the best way to judge performance.
9. Check Warranty, After-Sales Support & Parts Availability Even old generators must come with some form of:
Warranty on engine/alternator Service support Easy availability of spare parts
Jain Generator is known for offering reliable after-sales service and genuine spare parts for old and refurbished generators.
