Choosing the ideal generator for your industry is not a simple task. You need to analyze various factors such as the required power, fuel type, operation regime, and necessary maintenance. In this comprehensive guide, we will present the main characteristics of generators by industrial segment, fuel consumption, technical specifications, and the importance of load bank testing to ensure efficiency and prevent failures.
Required Power by Industrial Segment
The first step in choosing the ideal generator is determining the power needed to meet your industry’s demand. Below, we list the recommended power ranges for different segments:
Small Industries and Businesses
From 150 to 370 kVA. Generators in this range are ideal for small industries, supermarkets, shopping centers, and small hospitals.
Food and Beverage Industry
From 370 to 500 kVA. Models in this range meet the specific needs of the food sector.
Metallurgical, Steel, Cement, and Glass Industries
From 500 to 750 kVA. Sectors that demand higher power to operate heavy machinery.
Mining and Refineries
From 750 to 1000 kVA. Activities that require high power and reliability in energy supply.
Automotive Industry
From 1000 to 1500 kVA. Large factories with continuous production lines.
Oil Industry
From 1500 to 2500 kVA. Exploration and refining activities that demand very high power.
Operation Regimes
Generators can operate in three different regimes:
- Standby: For emergencies, when there is a failure in the main power grid. Should not exceed 200 hours of operation per year.
- Prime Power: For continuous use as a primary energy source. Ideal for locations without access to the conventional power grid.
- Base Power: Continuous and uninterrupted operation, with no limits on working hours.
Fuel Consumption
Fuel consumption varies according to the generator’s power and operation regime. For example:
- 150 kVA Generators: 32.6 l/h (standby), 31.3 l/h (prime), 29.3 l/h (base)
- 180 kVA Generators: 36.7 l/h (standby), 35 l/h (prime), 32.9 l/h (base)
- 260 kVA Generators: 59 l/h (standby), 52 l/h (prime), 49 l/h (base)
- 500 kVA Generators: approximately 95 l/h
- 700 kVA Generators: approximately 134 l/h
- 1500 kVA Generators: approximately 284 l/h
- 2500 kVA Generators: approximately 466 l/h
Preventive Maintenance
Preventive maintenance is essential to ensure the proper functioning of the generator. It is recommended to:
- Change lubricating oil and filter every 250 hours or 6 months (whichever comes first)
- Check the cooling system (up to 33 liters of water)
- Periodically inspect for leaks and wear
- Clean components and check belt tension
Importance of Load Bank Testing
Load bank testing is crucial to:
- Ensure the generator is operating at nominal power
- Identify problems before they cause failures
- Avoid fuel residue buildup
- Test the voltage regulator
- Ensure proper functioning of the cooling system
Annual testing is recommended to keep the generator in optimal working conditions.
Conclusion
Choosing the ideal generator for your industry requires a careful analysis of your business’s specific needs. Consider not only the required power but also the operation regime, fuel consumption, and maintenance costs. Remember that a well-sized generator with up-to-date maintenance can represent significant savings in the medium and long term.
