Emco Wheaton's Posi/Lock Blue delivers safe, spill free dispensing of urea. Engineered for the bus transit companies where vehicles need to be refueled at the same location every time. Opposed to open fill systems on the market which are open fill and which frequently result in a certain amount of urea being spilt each time during filling, this product directly dispenses to the vehicle. Urea tends to evaporate and the leftover ammonia crystallizes, creating a messy working environment. The urea might also run down the side of the bus staining paintwork and causing corrosion.
