- Operational Efficiency: Quick power availability leads to faster turnaround times for aircraft.
- Environmental Benefits: Lower emissions compared to running aircraft engines or APUs on the ground.
- Longevity of Equipment: Designed with high-quality components to last for years under heavy use.
Engine-Driven vs. Plug-In 140 KVA GPU
When choosing a 140 KVA GPU, one critical decision is between engine-driven and plug-in types.
- Engine-Driven GPU:
- Portable and ideal for remote airfields or locations without a stable power grid.
- Runs on diesel or other fuels, offering flexibility.
- Best suited for military operations and mobile applications.
- Plug-In GPU:
- Connected to the local power grid for continuous supply.
- Offers lower operating costs since no fuel is required.
- Perfect for large airports and maintenance hangars.
Both options are available under the JTL model series, allowing operators to select the best fit for their operational needs.
Evolution of JTL Series GPUs Since 2003
The JTL prefix models have been on the market for more than two decades, continuously evolving to meet modern requirements. Initially launched in 28.5VDC configurations, the product line expanded to include 38 KVA, 90 KVA, 120 KVA, and 140 KVA AC units.
