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 combines proven equipment with engineering expertise and lifecycle support for engine cleaning and cooling. RH Aero provides technical consulting and engineering services, including the design and development of engine cooling and cleaning systems tailored to specific engine and operational requirements. AeroJetVac™ is also available as a washing-as-a-service solution. The OEM-validated, vacuum-assisted, closed-loop process reduces water use and system risk, avoids dry-motoring entirely, and delivers consistent, repeatable outcomes—backed by RH Aero’s global service network.
