Microwave timber driver


Microwave timber dryer removes moisture from timbers to stabilize strength and dimensions, and prevent deformation and warping.

  • Very short drying time: 
    Microwaves directly act on water molecules to generate heat, so the drying time is much shorter than conventional method using hot air or air.
  • Uniform moisture content: 
    Microwaves can transfer heat evenly throughout timbers, preventing uneven moisture content.
  • Excellent drying quality: 
    Microwave drying can prevent the timber surface from cracking or deforming, helping to maintain timber quality.

Reliable Far-Field Microwave Wavelength Delivery

ETH’s microwave drying technology achieves extended reach, enabling deeper timber penetration for faster and more efficient drying.

Economical and Efficient

ETH’s microwave dryer is competitively priced compared to conventional dryers and boasts low maintenance costs. It also reduces drying time by over 70% through its efficient humidity removal, up and down air circulation, radiant heat, and automatic internal moisture control system, ensuring high-quality drying results.

Power-Saving Automatic Control Dryer

The dryer uses microwave technology to prevent timber from deformation and mold growth. It effectively dries the moisture from the inside of the timber with or without sealing, and the temperature and moisture are automatically controlled by a self-developed controller to save energy and ensure perfect drying.

Customizable for your space

System is installed to fit drying space.
