Since 1985 we have designed and manufactured both refractory-lined pit burners and trench burners. These units provide a safe and cost effective method of disposing of wood waste in suburban or metropolitan areas. All of our units meet Air Quality Standards, reduce costs and save landfill space. The McPherson Systems air curtain burner is affordable, and is available in many different sizes to fit your project needs.
