Comprehensive Planning & Production

From the beginning, Wellons has taken a systemic approach to the products it offers. We have the ability to offer a wood-fired boiler system complete from the point at which the fuel is received to the point at which the ash is transferred to the ash receiver. Every major component in the system is designed, engineered, manufactured, and installed by Wellons, from fuel storage to the secondary pollution control at the Electrostatic Precipitator. We also have this capability with our lumber drying systems, and our integrated lumber drying facilities.

Throughout the many years that we have been serving the wood products industry, we have always placed our emphasis on quality and integrity, and on placing our customers first on our list of priorities."
