The NUOENWEI PCA hose retriever hose is a specialized spiral hose that serves as the consumable core of modern Hose Retriever (HR) systems, transforming them into complete, automated PCA supply solutions. It is engineered to be deployed and retracted automatically, delivering cold or warm air from the PCA source directly to the aircraft interface.
The hose features a unique segmented design—with standard Start, Intermediate, and Final sections—allowing for customizable total lengths and easy maintenance. Constructed with an internal steel wire core, an external steel reinforcing strip, and a triple-layer insulated fabric build, it ensures leak-free performance, thermal efficiency, and long-term durability under constant movement and high pressure.

1. Engineered for Automated Hose Retriever Systems
The NUOENWEI PCA hose retriever hose is the core moving part of Hose Retriever systems, enabling safe, hands-free, and labor-saving deployment and retraction directly from PCA units. It is automation-ready, ensuring seamless integration with existing ground support equipment.
2. Modular Zip & Velcro Connection System
Industrial-grade zippers with Velcro seals allow for quick, tool-free assembly of hose sections, enabling customizable lengths and easy section replacement. This segmented design drastically reduces downtime and maintenance costs compared to replacing an entire hose.
3. Superior Triple-Layer Thermal Insulation
The three-layer construction (PVC-coated polyester fabric / PE foam / PVC-coated polyester fabric) minimizes thermal loss, prevents condensation, and maintains air temperature from source to aircraft. The air trapped within the insulation layers serves as a significant additional thermal barrier, ensuring energy-efficient operation.
4. Exceptional Strength with Lightweight Design
High tensile strength (≥2700 N) withstands pulling forces, while a low dead weight (2.8 kg/m) reduces load on the HR system for energy-efficient operation. The steel spiral reinforcement provides robust structural integrity without adding unnecessary weight.
5. High Compression Ratio for Space Savings
The hose can be compressed to a fraction of its extended length (compression ratio up to 1:9), drastically saving storage space on mobile PCA trucks or within fixed HR housing.
6. Aviation-Grade Fire Safety Compliance
Meets stringent fire resistance standards including NFPA 701 and UL94 VTM-0, operating reliably across a wide temperature range (-20°C to +70°C).
7. Mechanical Crimp Connection – No Welding
The steel wire is mechanically crimped onto the hose fabric—no welding required. This results in maximum hose extension life, easier operability, and reduced friction on the wing surface compared to PVC strip alternatives.
8. Reduced Weight & Improved Compression Ratio
Unlike traditional PVC stripe designs, the all-fabric construction with steel spiral reinforcement offers:
Aircraft Ground Air Conditioning (PCA Systems)
Primary application for delivering preconditioned air to parked aircraft cabins when the Auxiliary Power Unit (APU) is not operative
Airport Ground Support Equipment (GSE)
Integration into the fleet of support vehicles and fixed PCA systems at airport gates
Maintenance Hangar Air Ventilation
Effective ducting for climate control within large hangar facilities
Mobile and Fixed HVAC Ducting for Aviation
Reliable solution for heating, ventilation, and air conditioning needs in aviation environments
