Emco Wheaton ensures the safe refueling of diesel vehicles

Transport companies across North America are reaping the financial rewards and service reliability of a refueling system which totally eliminates the potential for accidental spillage and expensive contamination of fuels. Posi/Lock Blue, developed by Emco Wheaton, delivers safe, spill free dispensing of Urea and is particularly targeted at the bus transit companies where vehicles are being refueled at the same location every time.

Posi/Lock Blue represents a major breakthrough against 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. When this happens the Urea is exposed to air, the water then vaporizes and the ammonia will crystallize, creating a messy working environment. The Urea might also run down the side of the bus staining paintwork and cause damage to the body as it is highly corrosive. Posi/Lock Blue totally eliminates all such risks and makes refueling a whole lot easier for bus fleets and off highway equipment.

Under legislation first introduced in 2009, transport companies across North America were required to install special tanks containing “aqueous urea solutions” also known as AdBlue or DEF (Diesel Exhaust Fluid) to reduce harmful NOx emissions in diesel powered vehicles. But this raised another problem – the potential for accidental spillage and expensive contamination of fuels.

The new product works because it is smaller in scale than Emco Wheaton's traditional Posi/Lock system which prevents it from accidentally being connected to existing Posi/Lock 105 adapters or any other refueling systems on the market. This eliminates the risk of cross contamination and ensures the purity of the “aqueous urea solution.”

A no spill connection provides for a clean working environment and unmanned filling, allowing the operator to do other duties. Posi/Lock Blue is also lightweight and incorporates automatic shut off using vacuum technology, which ensures the tank is always filled to 85% of its capacity, eliminating the risk of overfilling as well underfilling.

The Posi/Lock Blue is already in use across North America and retrofit solutions are available for all buses.
