Optimal dehumidifier for wood materials and furniture storage?

+ Why have dehumidifiers been widely utilised in the wood industry for many years?

Inititially, let’s discover:

What does a dehumidifier do?

A dehumidifier is a device used to absorb (condense) and reduce moisture in the air within a closed environment. In similar conditions, the moisture content in wood is directly proportional to the surrounding air humidity.

Therefore, to maintain a low moisture content in wood, it is essential to keep the surrounding air humidity low, and a dehumidifier is used for this purpose

TIn the wood industry, dehumidifiers are commonly used in three different applications, each with distinct requirements: 

1. Dehumidifiers for raw material or finished wood storage:

As we know, raw or dried finished wood, when stored in a standard warehouse environment (with humidity similar to outdoor levels) or in a warehouse with air conditioning (where temperatures are lower than outside), will, over time, reabsorb moisture, causing the moisture content to exceed acceptable levels. The amount of moisture absorbed depends on the storage duration, ambient humidity (which varies by season, e.g., more moisture is absorbed during the rainy season than in the dry season), the type of wood (e.g., softwood absorbs more moisture than hardwood), etc.

2. Dehumidifiers for product drying rooms

Purpose: To ensure that the moisture content of the wood after drying is at or below 8%. This helps implement a recirculating drying system that maintains drying conditions throughout the year and saves drying energy by not venting outside.

3. Dehumidifiers for production workshops:

Purpose: To reduce moisture reabsorption during certain stages of the production process, particularly in specific manual operations where processing time is lengthy, involving small or thin pieces that can quickly reabsorb moisture.

Notes:

+ The air humidity in the warehouse does not directly correlate with the moisture content of the wood. Therefore, for a given moisture content in wood, you must consult the EMC (Equilibrium Moisture Content) table to select the corresponding temperature and humidity values. Do not equate the air humidity in the warehouse with the moisture content of the wood.

+ Wood moisture content is directly proportional to the surrounding air humidity—so to reduce the moisture content in wood, you must reduce the surrounding air humidity.
