💡 Executive Summary

Context: A large-scale garment export warehouse in Hanoi faced severe risks of product and packaging damage during the humid season.
The Challenge: High humidity causes mold on textiles and, critically, reduces the Box Compression Test (BCT) strength of cardboard boxes, leading to pallet collapse during container loading.
The Solution: Installation of the DeAir.RE-1200H heat-pump dryer (1200 kg/day capacity)—the largest standard model in DeAir's lineup.
The Result: Comprehensive humidity control, preservation of cardboard structural integrity, 50% energy savings, and a strong demonstration of DeAir's heavy-duty manufacturing capabilities.

1. The Hidden Logistics Pain Point: When Cardboard Boxes "Collapse"

1.1. The Silent Threat to Box Compression Strength (BCT)

In export logistics, few realize that ambient humidity exceeding 70% RH can reduce the Box Compression Test (BCT) strength of cardboard by up to 50%. When garment pallets are stacked high inside shipping containers, weakened cardboard leads to structural collapse, crushing the products inside. This results in millions of dollars in losses and rejected shipments by international partners.

1.2. Mold and the Challenge of Massive Volumes

A humid environment combined with textile dust creates the perfect breeding ground for mold and bacteria. Furthermore, garment warehouses typically feature high ceilings and massive volumes (thousands of cubic meters). This demands dehumidification equipment with an extremely high airflow rate (CMH) to effectively mix the air and eliminate moisture uniformly, preventing localized "humidity pockets."

2. DeAir.RE-1200H: The "Beast" of High-Capacity Dehumidification

To solve this complex equation, DeAir deployed the DeAir.RE-1200H, delivering impressive technical specifications:

🔧 OUTSTANDING TECHNICAL SPECIFICATIONS

Dehumidification Capacity: 1200 kg/day (at 30°C/70% RH).
Airflow Rate: 12,000 CMH, generating a continuous, powerful circulation of dry air throughout the massive warehouse.
Heat-Pump Technology: Recycles condensation heat, reducing electricity costs by 50-70% compared to traditional electric resistance heaters or legacy compressor systems.

3. Ultimate Customization Capability: From Garment Warehouses to Shipyards

While the DeAir.RE-1200H is the largest model in our standard product catalog, DeAir's limits do not stop there. As a direct manufacturer in Vietnam, we possess the R&D and engineering capability to design and build "mega-capacity" customized humidity control systems tailored to specific industrial demands.

A prime example of our heavy-duty manufacturing prowess is the custom-built DeAir.RE-2400H (double the capacity), engineered specifically for a marine shipyard paint booth. Such environments demand ultra-strict humidity control to prevent flash-rust on steel surfaces and ensure the perfect adhesion of marine-grade coatings.

4. Real-World Installation Process at the Hanoi Garment Warehouse

4.1. Strategic Positioning in the Climate-Controlled Warehouse

The machine was strategically positioned within the climate-controlled storage area. This ensures the dry air stream is distributed evenly across the textile and cardboard storage zones, eliminating any blind spots where humidity could accumulate.

DeAir.RE-1200H heat-pump dryer placed in the climate-controlled garment and cardboard warehouse — The DeAir.RE-1200H heat-pump dryer optimally positioned within the finished goods climate-controlled warehouse.

4.2. Safe and Professional Condensate Drainage Connection

With a capacity of 1200 kg/day, the volume of condensed water is substantial. The DeAir technical team designed a dedicated, automatic condensate drainage system that pipes the water directly outside the room, completely eliminating any risk of water leakage that could damage the cardboard boxes or warehouse flooring.

DeAir.RE-1200H dryer connected to external drainage pipe — The condensate drainage system is professionally connected and routed directly outside, ensuring absolute safety for the stored goods.

4.3. Operational Testing and Handover

Following installation, DeAir engineers and the client's representatives conducted a joint test run. They calibrated the target humidity setpoints (45-55% RH) on the control panel and provided comprehensive operational training to the warehouse staff.

Garment Condition	Prone to mold and musty odors	Dry, fresh, and fully export-compliant
Energy Costs (OPEX)	High (if using electric resistance/heaters)	50-70% savings via Heat-Pump technology
Risk of Shipment Rejection	High	Near Zero

6. Frequently Asked Questions (FAQ)

Q1: For a very large garment warehouse, how does the RE-1200H ensure uniform humidity control?

The DeAir.RE-1200H boasts a massive airflow rate of 12,000 CMH. Prior to installation, DeAir engineers perform Computational Fluid Dynamics (CFD) airflow simulations to determine the optimal machine placement and ducting layout, ensuring no localized "humidity pockets" exist within the warehouse.

Q2: Does the machine auto-drain condensate? Is there a risk of water leaking onto the cardboard boxes?

Yes, it is fully automatic. The system is designed with a dedicated condensate drainage pipe that routes water directly outside the warehouse or into the main drainage system, completely eliminating any risk of water leakage that could damage the goods.

Q3: If my factory requires a capacity larger than 1200kg/day, can DeAir accommodate that?

Absolutely. As a direct manufacturer, DeAir specializes in designing and building custom-engineered systems (such as the DeAir.RE-2400H or larger) tailored precisely to the specific moisture load calculations of your facility.

Q4: How does the OPEX of the RE-1200H compare to older solutions?

Thanks to Heat-Pump technology that recycles condensation heat, the electricity consumption of the DeAir.RE-1200H is only 30-50% of what traditional electric resistance dryers or legacy cooling systems would consume, allowing for a very rapid return on investment (ROI).
