Why will it only work on water cooled diesel motors?
It can be made to work on air cooled motors, such as the h& crank ones used for corn mills, but installation is a bit harder for them. BELIZEL taps into the coolant line of the water based diesel motors to get the free waste heat generated by the motor to heat the VO to lower it’s viscosity. With an air cooled diesel motor, we have to either use an electrical heater, or tap into the exhaust heat to lower the VO’s viscosity. It can be done, but you’ll have to contact us for an estimate on your specific application & needs. We’ll be making a conversion kit for these diesel motors as more people start requesting them.
