Silent 400 Hz turnarounds at remote stands with the ITW GSE 7400 eGPU

Airports that still roll a diesel GPU to a remote stand pay for it twice: once in fuel and maintenance, and again in noise, fumes, and carbon at the point of use. The ITW GSE 7400 eGPU is the battery-powered alternative — a 400 Hz ground power unit that is ready when you hit start, with no 15-minute diesel preheat.

ITW GSE introduced the world’s first battery-powered eGPU in 2017. The 7400 series now covers narrow- to wide-body aircraft at 90–180 kVA, plus the 28 V DC 7400 JetEx for business jets, regional, and military aircraft. Every model shares the same operator interface, so crews are not learning a new panel at every stand.

What operators actually get

This is a subtle but important difference from diesel GPUs and from some other battery units on the market. The 7400 uses tried lithium-battery technology at the input and ITW GSE’s solid-state converter at the output. You can recharge from a standard 50/60 Hz socket and supply aircraft power while recharging — useful in hangars and at remote stands that only have a wall outlet.

• No emissions at the point of use, and more than 40% CO₂ reduction during a typical turnaround versus diesel GPUs
• Silent operation — some crews have asked whether the unit is even running
• 8–10 narrow-body turnarounds per charge; ITW quotes up to 8–12 on a Boeing 737 depending on load
• ITW’s estimate of more than $390,000 OPEX savings on a 90 kVA unit versus diesel (hours-in-use dependent); TCO typically lower after about two years
• Replacing one diesel GPU can save about 50,000 kg (110,000 lbs) of CO₂ per year

Options that change how you work the ramp

The 7400 is available with one or two outlets for mixed fleets. Optional 32 A / 16 A auxiliary outlets on the 90 kVA unit let it act as a powerbank for selected GSE when it is not charging. Pair it with ITW GSE Power Share or a DC charger and you can top it up from surplus gate power — part of the EcoGate-ready ground power lineup we support.

ITW GSE Connect tracks units around the airfield so you can plan charging before the pack is too low. That is the difference between a battery GPU that is a science project and one that makes the bank.

How long can an eGPU run, and which aircraft does it cover?

Runtime depends on aircraft type and demand. ITW designed the 7400 for full turnaround cycles, with overnight charge or opportunity top-ups. The 400 Hz 90 and 180 kVA configurations cover regional turboprops through wide-body jets. The JetEx 28 V DC model is rated for up to 100 engine starts on a full charge.
