Emco Wheaton Posi-Lock BLUE, Urea Dispensing System

PLEASE EMAIL US FOR PRICING

The PosiLock Blue DEF system consists of a durable nozzle and an accompanying adaptor that is connected to the onboard DEF/AdBlue tank. It operates the same way as the industry recognised PosiLock 105 system, providing a clean and safe working environment. Contamination of a DEF/AdBlue with diesel is a serious issue that can not only damage a vehicle’s engine but also cause explosions, as such it’s vital to ensure both mediums are kept apart. This is done through the PosiLock Blue’s selective interface that is unable to be interchanged with any other fuel system. Other benefits include dry-break disconnect couplings that eliminate spillages, automatic shut off that permits unattended operation and a vacuum shut off mechanism that protects the tank from exposure to positive pressure. Like the PosiLock 105, this product also has a pre-set level to guarantee filling is consistent and protects against theft as no access is possible without an active connection. This system is an ideal retrofit solution as it requires no cutting or dropping tanks. Better still, no new training is required if users are familiar with the PosiLock 105 refueling system. Materials of all wetted components comply with ISO 22241 requirements.

Operation:

To begin fueling, the operator connects the nozzle to the adapter and the fill lever is activated. The fluid flow creates low pressure in the trip rod assembly. The low pressure created causes air in the tank to travel upwards to the sensing tube and into the trip rod assembly. Once the fluid level reaches the sensing tube outlet, air can no longer travel from the tank, creating a vacuum in the trip rod assembly. This vacuum is used to actuate a diaphragm in the trip rod assembly, automatically shutting off the fueling process. System requires a flow rate of 5 to 10 gallons per minute (19-38L/min.).

Operation Savings and Benefits:

• Quick retrofit of existing buses - No cutting or dropping tanks required.
• Vacuum shut off feature - Plastic tank is not exposed to any positive pressure.
• Dry-Break feature - No spill which provides a clean and safe environment.
• Flow Rate - Capable of flow rates of up to 10 GPM (38L/min).
• ISO 22241 compliant – Material of all wetted components complies with ISO requirements.

Potential Cost Savings:

• Auto Shut off - No risk of overfilling.
• Preset fill level - Guarantees consistent filling.
• No new training necessary - Uses same reliable operating procedures as Posi/Lock 105 diesel refueling systems.
• Selective System – The interface of the Emco Wheaton UREA dispensing system is unique and will not interchange with any other system, eliminating the risk of cross contamination.
