Pack more Heat!
Add a super-efficient heat exchanger for proper oil temp and faster switchovers.
Most auto coolant systems run at 180 degrees Fahrenheit. Did you know that the optimal WVO temperature for proper combustion is 180 as well? It makes sense to take advantage of the coolant heat to warm the vegetable oil for proper combustion temps. The waste oil community has been doing this for over a decade. In the search for ever more efficient and effective means of heating waste oil, folks tried out Flat Plate Heat Exchangers, which have traditionally been used for beer chilling, radiant floor heating, solar applications, etc. These exchangers are really efficeint as they have a high surface are for heat exchange. The results have been phenomenal in the regards to how efficiently these FPHE’s work, providing excellent transfer of heat while taking up little space. They work so well that they have become an industry standard for WVO Conversions. You will be hard-pressed to find a vehicle without one, as long as the owner is concerned about properly heating their oil.
WVO Designs has brought you another solution for running on waste vegetable oil. With these high quality, custom heat exchangers, you will optimize your oil temps at minimal costs.
How it works: Coolant and Oil are fed through multiple flat channels of stainless steel, providing a large surface area for heat exchange.
