🚀 RAAL delivers a simple, safer, and cost-effective GPU upgrade solution for HAECO Hanger 2 MRO

​

We’re proud to partner with ITW GSE to modernise the 400Hz ground power infrastructure at HAECO’s Hanger 2 (Bays 4, 5, 6 and workshop).

The existing central system — three shared 120kVA GPUs with aging paralleling switchboards and distribution — was creating operational risk, instability, and limited headroom for growth. HAECO needed a future-ready solution that could be implemented efficiently without a complete rip-and-replace of the cabling infrastructure.

​

Our designed Engineering Solution:

• Option 1: 2 × 90kVA Power Coil + 5 × 90kVA ITW GSE GPUs

 

Both configurations leverage Plug & Play technology, re-use of existing cables where possible, and dedicated power delivery per bay. Detailed voltage drop calculations (even on the longest runs up to ~135m) confirm stable 115V ±3V at the aircraft plug — well within tolerance and with margin to spare.

Key outcomes for HAECO:

• Faster aircraft turnaround and higher MRO throughput

• Significantly improved operational reliability and flexibility

• Reduced maintenance burden and long-term operating costs

• Full compliance with current industry standards

• Strong return on investment through minimised downtime and optimised infrastructure

 

This is a practical, high-impact upgrade — not over-engineered, but thoughtfully designed to deliver measurable efficiency, safety, and productivity gains.

 

Thank you to the HAECO team for the opportunity to support their world-class MRO operations in Hong Kong.

If you’re facing similar challenges with aging GPU infrastructure, limited scalability, or high maintenance costs in your hangars, I’d be happy to share more details on how this approach can be adapted to your facility.
