Airlines worldwide rely on innovative, operator-friendly solutions for engine cleaning. RH Aero’s Engine Wash & Cool System, the AeroJetVac, is fully self-contained, meets OEM requirements and dramatically cuts ground time.
Fast, Autonomous and Safe
The diesel-powered AeroJetVac unit combines cooling, washing, rinsing and drying in a single 90-minute process—without wind restrictions and without dry-motoring.
A 400-litre water tank, integrated detergent reservoir, vacuum unit and closed-loop effluent capture mean no external connections are required. Only two technicians are needed; no cockpit crew or B1-licensed engineer has to be on site.
Your Benefit
-
Lower operating costs – up to three-times higher cumulative fuel and CO₂ savings when washing every 100 flight cycles.
-
Minimal water use – only about 90 L of fresh water per cycle; all effluent is fully contained.
-
Starter protection – no starter-motor wear thanks to the elimination of dry-motoring.
-
Maximum safety – no bleed-air or oil-line intrusion; eliminates known causes of cabin-odour events.
- OEM-approved – validated for Rolls-Royce Trent XWB, 1000 and 7000; 900/700 in qualification.

One system – four phases
- Cooling: High-volume air cools the engine to ≤ 60 °C, allowing earlier maintenance access.
- Washing: Low-pressure spray nozzles apply biodegradable detergent evenly to all compressor stages.
- Rinsing: Precise rinse lances remove detergent residues without introducing water into pneumatic or oil systems.
- Drying: A warm-air stream dries the core so the aircraft can return to service immediately.
Whether for a gate-side turnaround, a performance wash or line-maintenance cooling, the system covers all common use cases while preserving engine integrity.
