Hydro Thermo Plants

What is Hydro-Thermo™ Modification of wood?

You have a lot of options when it comes to wood treatment. Thermo modification is one of the latest trends in the wood conservation field. In fact, thermo conservation is the most popular and hottest-growing segment today, worldwide. Thermo conservation is hyper-environmentally friendly and is useful for a variety of products: outdoor furniture, cladding, decking, flooring and cabinetry. You’ll need the right equipment to get the job done, and that’s where American Wood Technology can help, especially with our unique Hydro-Thermo™ modification process.


Take your wood treatment to the next level with our Hydro-Thermo™ modification “factory-in-a-box.” We offer plants of any size based on your needs and specifications. Not only are these plants customizable to your needs, but they come with a plethora of benefits for you to take advantage of.

You can get more quality out faster – as short as 12-18 hour charges for some species, leading to lower production and investment costs. It’s not just about affordability, however. The product quality is also superb in comparison with other systems, and it can easily be operated with different load levels. As an added bonus, the system can be emission-free.

What is Hydro-Thermo™ Modification?

The Hydro-Thermo™ modification process involves using steam to heat up lumber under pressure to between 170 to 220 degrees Celsius (or 338 to 428 degrees Fahrenheit). This process effectively burns off the hemi-cellulose and creates some exciting new properties, including:

Exotic Color:

Ordinary wood adopts a warm brown color throughout, making it look like more tropical hardwoods.

Environmentally Friendly:

You can use more common species instead of tropical hardwood.

Reduced Equilibrium Moisture:

The process reduces the MC Equilibrium by up to 50%, resulting in less water re-absorption, swelling, twisting, bowing, shrinking and cracking.

Upgrade From Rustic:

Due to color defects, it’s not uncommon for light-colored wood to be downgraded to rustic when used in flooring and components. The modification process, however, blends the color of the wood, thus increasing wood value.




Embrace the efficiency and sustainability of MOLDRUP TMT, a revolutionary approach to wood preservation that transcends conventional methods. Unlike typical treatments that utilize dry heat and risk reducing moisture levels too significantly-potentially leading to damage and cracking-MODLRUP TMT employs a precise application of varying steam pressure. This technique ensures wood maintains an optimal moisture content of 2-4 percent, guaranteeing both control and exceptional quality.

MOLDRUP TMT stands out for its rapid processing time and ease of operation, offering a swift, high quality treatment with a proven track record of success. The environment to durability is evident in the construction of our equipment, with components such as valves and bearings made from premium stainless steel.
