2 x 6 wood pellet fired evaperator 600 cdl ro 1 season on ro . Filter press, bottler sap tanks new syrup drums , lines taps . Complete operation . I prossed about 500 gallons of sap per hour into syrup with this arangment. I was able to run everything by my self with ease. The wood pellet evaperator runs constant heat. No stopping to fill like wood . I love this setup can easly handle 2000 taps . I am getting out of the maple business
