What are the applications for a 1250 kVA generator?
A 1250 kVA generator is used in large-scale industrial operations, major hospitals, data centers, and other facilities that require a significant and reliable power supply. In industrial operations, it powers heavy machinery, production lines, and other critical equipment. Hospitals use 1250 kVA generators to ensure that life-saving medical equipment, lighting, and HVAC systems continue to function during power outages. Data centers rely on these generators to maintain server uptime and prevent data loss during grid failures.
How reliable is a 1250 kVA generator for continuous use?
A 1250 kVA generator is extremely reliable for continuous or prime power applications. It is built to handle heavy loads and operate for extended periods without interruption. Reliability is further enhanced by features like automatic start, remote monitoring, and advanced control systems that ensure consistent performance. Regular maintenance, including oil changes, filter replacements, and system inspections, is essential to maintain this reliability and prevent unexpected failures.
What are the running costs of a 1250 kVA generator?
The running costs of a 1250 kVA generator include fuel, maintenance, and potential wear and tear on parts. At full load, fuel consumption typically ranges around 60 litres per hour. Maintenance costs include routine services like oil changes, filter replacements, and inspections. Over time, investing in regular maintenance can reduce the likelihood of costly repairs and extend the generator’s lifespan. For businesses with high power demands, these costs should be factored into the total cost of ownership to ensure long-term affordability.
