Keyfeatures
Gate-side turnaround: Performs a full wash with engine cowl doors closed, eliminating repositioning and enabling same-slot departure.
Frequent performance washes: Short, repeatable 90-minute cycle lets operators increase wash intervals, tripling cumulative fuel & CO₂ savings.
Line maintenance cooling: High-velocity air cooling brings hot engines down to 60 °C, allowing earlier access for other maintenance tasks.
Single-slot fleet washes: Four-engine capacity means all engines on one wide-body can be washed within the same maintenance window, saving 6–8 hours gate-to-gate.
Remote or utility-limited bases: On-board power, water and detergent supply eliminate the need for local infrastructure.
Highlights
Operational
< 90 min gate-to-gate with a pre-programmed cycle—no wind restrictions and no engine run.
Cowl doors stay closed; aircraft is available immediately after the wash.
Two-technician task; no cockpit / B1 crew on site.
Efficiency & Cost
Bigger cumulative fuel savings by washing more often without disrupting schedules.
No dry-motoring—cuts starter-motor wear and avoids known reasons for cabin-odour reports.
Lower labour burden: shift from 3–4 engineers to two technicians per wash.
Environmental
Closed-loop effluent capture—zero runway runoff.
~ 90 L water per cycle (vs. 150–200 L in typical high-pressure washes), reclaimed and stored on-rig.
Biodegradable detergent meeting stringent discharge rules.
Application Cases
Commercial & Regional Fleets – On-wing turbofan cooling and core washing during regular gate turns and overnight layovers.
MRO & Line Stations – Scheduled wash campaigns and corrective engine-wash events without relocating aircraft to remote wash facilities.
Configuration Options
Safety & Operation
The integrated cool-and-wash sequence is engineered to avoid dry motoring, reducing stress on starters and minimizing unnecessary engine ground operation.
Process control and defined steps help maintain conformance with OEM engine-wash and cooling requirements for multiple turbofan types.
Gate-side operation without cowl opening enables cleaning in a stable configuration and reduces the risk associated with additional maintenance disturbance.
Enclosed fluid handling and defined effluent capture help keep work areas clean and reduce slip and contamination hazards around the aircraft.
Repeatable procedures support consistent wash quality across stations, enabling predictable engine performance recovery and on-wing time benefits.
Mobility & Transport
The self-contained, diesel-powered unit can be positioned directly at the gate, avoiding tows to remote wash pads or specialized stands.
Closed-loop utilities allow deployment wherever the aircraft parks, independent of local water, power, or drainage infrastructure.
Compact operational footprint is designed to integrate into normal gate operations and standard ramp-flow patterns.
Durability & Corrosion Protection
Closed-loop effluent capture minimizes uncontrolled discharge of wash fluids, helping protect aircraft surfaces and ramp infrastructure from residual contamination.
Regular, controlled engine core washing supports cleaner gas paths, which is associated with improved efficiency and reduced deposit-related degradation over time.
System design and proven field use across hundreds of washes demonstrate suitability for repeated deployment in airline and MRO environments.
Why RH Aero?
AeroJetVac™ is more than a wash cart—it’s a proven, OEM-validated process delivered by the team that designs the equipment, supports it on the ramp, and stands behind your results. Our vacuum-assisted, closed-loop method reduces water use and system risk, avoids dry-motoring entirely, and returns aircraft to service with consistent, repeatable outcomes—backed by RH Aero’s global service network.
