  • • How many gallons can be processed per

    batch?

    • How long does each batch take to process?

    • Is the system capable of heating the oil

    and/or the alcohol-catalyst mixture?

    • Does the system include methanol recovery

    equipment? Methanol transfer system? Test kits?

    • Does the system have the capability to wash

    and dry the biodiesel?

    • Does the system require any extra

    plumbing, fittings or pumps?

    • Does the system require that a specific catalyst be

    used?

    • Does the manufacturer provide technical support?
