Equipment designed to force preservatives deep into lumber utilizes hydraulic pressure to impregnate wood cells with chemical solutions. This process protects the material from insect infestation, fungal decay, and rot, significantly extending its lifespan. A typical system includes a treatment cylinder, pressure pumps, a reservoir for the preservative solution, and a control system to manage the treatment cycle.
Protecting wood from deterioration is essential for numerous applications, particularly in outdoor and harsh environments. Historically, simpler methods like brushing or dipping provided limited protection. Modern pressurized systems offer significantly enhanced penetration and longevity, leading to more durable structures, fences, decking, and utility poles. This preservation contributes to resource conservation by reducing the need for frequent replacement.
