When you need to move heated or refrigerated air over distances without energy loss, ordinary ventilation hoses fail. The NUOENWEI Portable Insulated Ducting is specifically designed for high‑efficiency thermal air transfer. Its unique 4‑layer construction (outer PVC coated fabric, middle 3mm insulation, inner PVC mesh fabric, and a spiral steel helix) minimizes heat exchange with the environment, keeping cold air cold and hot air hot.

Energy saving – 3mm insulation layer reduces thermal loss by up to 40% compared to non‑insulated ducts.
Long service life – UV‑resistant outer PVC resists sunlight degradation;Wear-resistant rubber strips extends life when dragged.
Quick connection – 10cm soft ends (no wire) allow easy clamping to grain cooler outlets or tent AC ports.
Multi‑color options – Yellow is standard; gray, white, blue, red, black, green available for job site coding or brand matching.
No condensation – Insulation prevents surface sweating even when conveying cold air in humid environments.
1. Grain Storage & Silo Cooling
Connect directly to grain cooler units to inject cool, dry air into silos. Prevents mold and insect infestation. The 4″–59″ diameter range fits any commercial grain cooler outlet.
2. Outdoor Tents & Temporary Shelters
Ideal for large event tents, military shelters, or camping setups where a portable AC or heater is used. The flexible duct snakes around poles and furniture without kinking.
3. Special Air Conditioners (Industrial AC)
Used with spot coolers, portable industrial ACs, or HVAC systems that require temporary or semi‑permanent ducting extensions.
4. Ventilation for Confined Spaces
Can be used for exhausting fumes or supplying fresh air in construction, marine, or agricultural confined spaces (check local safety codes for exhaust applications).
5. Cold Chain & Refrigerated Transport
As a portable insulated air transfer hose for loading docks or temporary cooling loops.
