Like oil control V2, but with some extensions:

Complete kit in heated isolated metal housings

• heated and isolated oiltank and lines, fat remains at least 24 hours liquid when the tank is half full and at 0°C outside temperature (optional and with a minimum surcharge stronger isolation available if enough place is present)
• control unit recognizes automatically when the fat becomes liquid and switches only then on veg. oil
• extra large air driven diaphragm fuel pump
• automatic fast-flush when turning off; Engine stays on till the injection system is completely flushed with diesel and only after that time or over an emergency stop it could be turned off
• with emergency turned off the injection system is flushed by high-pressure pump with Diesel after turning off, so that the fuel in the lines does not become crystal
• without electricity the conversion kit runs on diesels

So you can say that this conversion kit is absolutely reliable.

You won't find a better, more SAFE or even an FULL/100% automatic system like this
