Benefits
Optimal humidity ensures dimensional stability, precise processing, and long-lasting wood quality. Condair’s humidification and dehumidification systems help manufacturers control air humidity efficiently, reducing waste and energy costs.
Consistent quality & precision
45–55% humidity keeps wood stable, avoiding warping, cracking, swelling, and ensuring quality.
Safer work & less dust
Below 45% RH causes static and dust; controlled humidity ensures safety and a cleaner workshop.
Strong bonds & lamination
Stable 50–55% RH ensures adhesives cure properly, preventing delamination and joint failure
Humidity Control in Wood Working
Problems with gluing and laminating
Problems with gluing and laminating are not uncommon. Glues often do not cure completely and evenly in dry conditions. Gluing problems also frequently occur with poorly fitting parts. Dry air can often cause glue joints to come apart or veneers to peel off the base wood when dimensions change or parts twist or “crack.”
Problems with static electricity
Problems with static electricity in a woodworking environment occur when dry air causes surfaces to become charged with static electricity. This leads to a variety of problems such as dust fires and static explosions. In some cases, static electricity can also affect the adhesion of paints and coatings to wood.
Sawn timber drying and storage
Dehumidification or drying can be an important factor in wood storage, ensuring smooth production afterwards. This prevents deformation, warping, or surface cracks, and the tearing or splitting of joints and frame corners can also be prevented by conditioning the wood appropriately. Dried sawn timber, for example for furniture production, may have a maximum moisture content of 8-9%. For other wood, for example for doors or windows, the moisture content may be a maximum of 12%. If this type of wood is stored in rooms without dehumidification, the result can be highly fluctuating quality. Changing moisture levels can cause changes in the wood structure and lead to processing problems during final processing. This results in high rejection rates due to poor product quality.

Use cases
Prevent evaporative losses
Organic materials have an internal moisture content and will lose moisture to the atmosphere when exposed to air with a low humidity. Humidifiers are used to create an environment with perfect balance between the material’s internal moisture content and the air’s relative humidity.
Anti-static and ESD prevention
Low humidity increases static build-up because dry air is an insulator, making electrostatic discharge (ESD) more likely. Maintaining 40–60% relative humidity helps dissipate charges and significantly reduces ESD risk.
Prevent condensation and mould
By combining a professional ventilation system with the Condair DA adsorption dryer, it is possible to achieve optimal results in preventing condensation and mould.

Pinetum Furniture
Condair has supplied and installed a JetSpray humidification system to Pinetum, a pine furniture manufacturer based in Wiltshire. 116 nozzles, which combine compressed air and water to produce a fine atomising spray, humidifying the company's timber store, machine shop and assembly areas, maintaining the humidity at 60% relative humidity. 525 litres of water are pumped into the atmosphere every hour around Pinetum's production facility, ensuring that the timber being worked and stored there remains in total equilibrium with its environment.

Nemschof Inc, USA
Nemschoff, the highly regarded healthcare‘furniture manufacturer in Sheboygan, Wisconsin, faced serious production problems when its 60,000¯sq¯ft casegoods plant dropped to relative humidity (RH) levels as low as 12%. The dry air caused wood panels™ moisture content to drop to 3‘4¯%, leading to massive waste: 25“30% of panels split and were discarded at a cost of¯$90“$100 each. Seeking an energy‘efficient, low‘maintenance alternative to compressed‘air and boiler steam systems, they selected Condair™s engineered ML humidification system. Installed and calibrated across zones, the ML Princess units maintained RH above 35%. The result: splitting of hardwood panels fell from around 25‘30% to just 1‘2%. The solution delivered significant cost savings, increased productivity and better scheduling reliability. Nemschoff now plans to upgrade additional plants with Condair systems.
