The fuel dispensers TATSUNO of the series OCEAN Euro/AdBlue® serve for dispensing of the medium AdBlue® into road vehicles, especially heavy-duty trucks that run on diesel fuel, on retail and commercial outlets. They are progressive single- or double-sided fuel dispensers with one to two hoses for dispensing from either one or both sides simultaneously. The fuel dispensers are equipped with a high-quality Japanese hydraulic system TATSUNO and with a reliable electronic calculator. All fuel dispensers of the series OCEAN are operated both in the manual mode (i.e. off-line), and in the automatic mode, where the fuel dispenser is linked with the kiosk control system and the data concerning volume, sum and price are transmitted to POS.
