Evolution biodiesel
• 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?
