Keyfeatures
Two-Mode Steam Process – Operates in Wash Mode (1:10 agent ratio) and Rinse Mode (steam only) for consistent, residue-free cleaning.
Environmental Compliance – Integrated wastewater capture and filtration minimize ecological impact and chemical exposure.
Rapid Turnaround – Quick setup and 5-minute drying cycles reduce overall maintenance time by up to 80 %.
Operator Flexibility – Deployable at gates, airside, or remote stands without hangar access.
Scalable System Architecture – Available in three configurations: Cleaning Unit, Complete System with lift, or fully autonomous unit with onboard power.
Highlights
The RH Aero APU Cleaning System delivers a controlled, repeatable process that cuts downtime, chemical use, and air-quality events across A320 fleets.

Configuration Options
Safety & Operation
Steam temperature limited to ≤ 100 °C and pressure ≤ 1 bar ensures safe cleaning of sensitive components.
Process validated against AMM 49-16-00-100-005-A and 49-00-00-100-003-A requirements.
Ardrox 6085 cleaning agent applied in controlled 1:10 dilution.
Documented cycles guarantee repeatability and compliance with OEM cleaning intervals.
Filtration system prevents chemical release to the environment.
Mobility & Transport
Compact design fits ground support vehicles and maintenance trailers.
Available lift-platform variant allows direct access to APU compartments.
Optional power-generator package ensures full autonomy for remote operations.
Durability & Corrosion Protection
Stainless-steel and treated-aluminum components resist heat, moisture, and chemical exposure.
Sealed systems prevent contamination and corrosion from cleaning fluids.
Low-maintenance construction ensures consistent performance over repeated use.
