Our Advanced Process Creates Better Wood While Respecting the Evvironment

Our state-of-the-art EcoDryers are practical, proven and production ready. Thermowood producers in Europe have spent the past 10-15 years establishing value and setting international standards for a range of wood products. Now Superior Thermowood (STW) is bringing a fresh approach to the North American market.

STW developed and employs a unique system that utilizes advanced computer systems to monitor and control the routing of intense heat and steam through a pressurized air-flow management system. The design ensures thorough heat distribution and a maximization of the process while minimizing overheating or under treating. A series of sophisticated sensors are strategically positioned within the EcoDryer to analyze the drying process until the targeted moisture content (typically less than 8%*) is achieved. The result is Superior Thermowood, a value added product that’s dimensionally stable, resistant to twisting and warping, and suitable for use indoors and outdoors without toxic chemical treatments.

Our EcoDryers are capable of processing large volumes of wood in less time and without the waste that often results from traditional dry kilns (due to cracking, twisting and warping). Currently EcoDryers are fired by either gas or oil systems, however alternatives like wood waste and biomass fuel sources are currently being studied.

It’s lighter, better looking and because our process requires only 24-48 hours for completion,* maintaining a “just-in-time” job-ready inventory is much eaqsier.




• STW’s EcoDryers are principally a “closed loop” system. Other thermowood processes usually exhaust the waste, heat and energy into the atmosphere.

• Superior Thermowood’s design constantly recirculates the hot air and steam, along with the gases and emissions that are given off by the wood, burning them off during the process.

• Condensate is collected in a tank below the EcoDryer for treatment.

• In the future, wood waste or biomass will be utilized as a fuel source.
