Meeting EU & US Export Standards: The Critical Role of Dehumidifiers in the Wood Processing Industry

Vietnam's Wood Industry "Rejoins the Race" for Exports: The Invisible Challenge of Humidity

In late 2025, Vietnam's wood processing and export industry is showing strong signs of recovery, especially with high-value orders from demanding markets like the United States and the EU. To conquer and maintain a strong position in these markets, product quality is paramount. However, there is an invisible yet critical "technical barrier" that every business must overcome: humidity control.

The "Breathing" of Wood: Why Vietnamese Wood is Prone to Warping and Cracking When Exported

Wood is a natural, hygroscopic material, meaning it always tends to absorb or release moisture to equalize with the humidity of its surrounding environment. This is the root of the problem:

• In Vietnam: The tropical monsoon climate has very high air humidity (typically 75-85% RH). Raw and finished wood naturally acclimatizes to this high moisture level.
• In Europe/USA: The temperate climate is much drier, with indoor air humidity often at only 30-50% RH.

When a furniture product from Vietnam is shipped to a drier environment, the wood begins to "breathe" – rapidly and unevenly releasing moisture. This process causes shrinkage, leading to severe consequences such as warping, surface cracking, and peeling of the PU paint finish, completely destroying the product's value and the exporter's reputation.

To prevent this, the "golden standard" in the wood export industry is to dry the wood to a stable Moisture Content (MC) of 8-12% and maintain it throughout production and storage. This is the equilibrium moisture content suitable for most indoor environments in importing countries, as recommended by reputable organizations like the U.S. Forest Service.

DeAir's Comprehensive Humidity Control Solution for the Production Chain

DeAir provides technological solutions for the entire cycle, from processing raw wood to preserving finished products before export.

Stage 1: Drying Raw Wood (Bringing MC down to 8-12%)

Traditional kiln drying can be energy-intensive and may cause wood to crack due to high temperatures. The modern solution is the Daxwell Heat Pump Dryer. Its low-temperature drying technology allows the wood to dry slowly and evenly from the inside out, minimizing cracking while saving 40-60% on energy compared to resistance heating.

Stage 2: Controlling the Production & Storage Environment (Maintaining 50-60% RH)

After the wood has reached the standard moisture content, preventing it from reabsorbing ambient moisture is crucial. The DeAir.RE Industrial Dehumidifier maintains the air humidity in the entire factory and finished goods warehouse at a safe level (50-60% RH). This ensures the wood's MC remains stable at 8-12% until shipment, which is especially critical in sensitive areas like the PU paint room, where high humidity can ruin the finish.

A DeAir.RE dehumidifier maintains stable humidity in the finished wood warehouse, ready for export.

Real-World Case Study: DeAir Provides Humidity Control for a 3000m² Wood Warehouse

Seeing is believing. DeAir has successfully implemented numerous large-scale projects for the wood industry. The video below is a real-world testament to our capabilities at a 3000m² wood warehouse, where DeAir installed a system of 43 DeAir.RE-600 dehumidifiers combined with 12 circulation fans. This solution provides comprehensive humidity control, preventing warping and mold, and protecting the quality of the finished wood products.
