APA-100 Combined Ground Power Unit

The APA-100 occupies the sweet spot between the mid-range APA-110 and the heavyweight APA-165: it is described by ElectroAir as the most compact unit in their diesel GPU series, yet it delivers the same 90 kVA AC and 800 A DC specification as the top-tier EACR-90/800 solid-state unit, packed into a single diesel-driven mobile chassis. The Deutz TCD 3.6 Stage V (Tier 4) engine brings it into compliance with current European emissions regulations, making it suitable for airports enforcing Stage V GSE requirements — an increasingly common procurement condition at European and GCC hub airports investing in sustainability programmes. Both AC and DC output channels operate simultaneously and independently, allowing an operator to power aircraft avionics via 400 Hz while supporting DC-dependent systems or starter functions from the same unit. A 10.1-inch anti-glare sunlight-readable touchscreen provides the operator interface — practical for Gulf ramp conditions where direct sun renders standard screens unreadable. Noise output is rated below 75 dBA at seven metres, meeting typical airport GSE noise limits. An optional plug-in hybrid function allows shore-power operation for zero-emission hangar use. For procurement engineers weighing footprint against output, the APA-100 is the right answer when apron space is constrained, Stage V compliance is mandatory, and both AC and DC servicing are required from a single asset.
