Trusted Portable Home Dehumidifier Exporter & Supplier

Compressor-based dehumidifiers pull moist room air over a cold refrigerated coil, causing water vapor to condense and drip into a tank. They are exceptionally energy-efficient in warm, humid climates (above 20°C). However, when room temperatures drop below 15°C, compressor coils tend to frost over, requiring frequent defrost cycles that drastically lower performance. Desiccant dehumidifiers utilize a slowly rotating wheel coated with synthetic zeolites or silica gel to absorb water molecules directly from air without condensation. They function reliably down to sub-zero temperatures (0°C to -20°C), making them essential for unheated winter homes, northern cellars, and specialized storage.

Hangzhou DryAir achieves supply air dew points down to -70°C by utilizing multi-stage desiccant rotor combinations coupled with deep chilling pre-cooling coils. The primary cooling coil removes the bulk latent moisture load, after which high-reactivity desiccant wheels strip remaining traces of moisture down to fractions of a gram per kilogram of dry air. Our proprietary sealing structures prevent cross-leakage between process and regeneration air sectors, guaranteed by in-house psychrometric performance testing before global shipment.

Yes. We provide complete turnkey OEM/ODM export solutions. This includes injection molding customization, bespoke housing aesthetics, custom front-panel human-machine interfaces (HMI), localized companion mobile apps (Tuya/SmartLife IoT frameworks), localized packaging, customized user manuals in any required language, and compliance testing documentation stamped under your brand name for retail or distribution authorization.

Depending on your regional market, our dehumidification and air treatment platforms are built to satisfy UL (US), CSA (Canada), CE-LVD/EMC (European Union), RoHS, REACH, and EAC (Eurasian Economic Union) safety and environmental requirements. Furthermore, our manufacturing facility operates strictly in conformance with ISO 9001 quality management and GJB military equipment standards.

For standard OEM branded portable series, typical minimum order quantities start at one 20ft or 40ft high-cube shipping container (approx. 350 to 900 units depending on chassis size). Production lead times for recurring orders generally range between 25 to 35 business days. Bespoke engineered desiccant skids and turnkey dry room assemblies follow a project-specific timeline of 6 to 10 weeks including full factory acceptance testing (FAT).

Standard export contracts include 1% to 2% complimentary spare parts delivered inside each sea container (PCBs, sensors, motors, float switches). In addition, we offer an optional 2-year overseas technical service agreement that includes priority component dispatch, remote digital video diagnostic sessions with our registered HVAC engineers, and on-site engineering dispatch for commercial and industrial installations worldwide.
