Overview
Wash engines at the gate in < 90 min | No engine run | Cowl doors stay closed | Cool the engine in ~ 20 min.
AeroJetVac™ is a self-contained Engine Wash & Cool System, electrical or diesel-powered rig that cools and washes turbofan engines right at the gate in about 90 minutes. It carries its own 400 L water tank, detergent reservoir, vacuum unit and closed-loop effluent collector. One cycle uses only ~90 L of fresh water, all of which is captured for safe disposal. The system is validated for Rolls-Royce Trent XWB, Trent 1000 and Trent 7000 engines, with Trent 900 and Trent 700 qualifications in progress.
Use Cases
Gate-side turnaround: AeroJetVac™ 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.
Benefits
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.
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.
