Read below to learn more about Wiggins Patented JNX Fast Fueling Systems

The Patented JNX Series Non-Pressurizing Fast Fueling System
(Fast, Clean and ULTRA SAFE)

The Wiggins JNX non pressurizing system allows for automatic diesel refueling at up to 211 gpm (800 lpm) with existing Wiggins nozzles and does not pressurize the fuel tank.  Shutoff is automatic, fully self contained and cannot be overridden.  

Competitors' Non Pressurizing Systems

Competitors' non pressurizing systems use float valves and are FAIL OPEN systems.  They will overfill and pressurize the fuel tank if fueling is carried out with a faulty float valve or bleed hose.  (Competitors' systems commonly make use of an internal bleed hose, which is vulnerable to fatigue due to fuel slosh.)  In this situation, fuel continues to bleed through the faulty float valve or hose even when the fuel level has passed the required shutoff point, preventing pressure from equalizing across the shutoff piston.  The pressure imbalance keeps the piston open and fuel continues to flow into the tank unchecked.  Consequently, the tank overfills and is pressurized in proportion to the flow rate - the higher the flow rate, the greater the spillage and pressure build up - creating a potentially severe safety and environmental hazard. 

The Wiggins Patented ULTRA SAFE JNX System

The Wiggins JNX system represents a technological leap forward in non pressurizing automatic diesel refueling systems.  The JNX system uses conventional pressure sensitive fuel nozzles such as the Wiggins ZZ9A1 and ZZ9A2 while providing users with unique fail shut and overfill resistant features not matched by the competition. 

The Wiggins JNX shutoff valve is FAIL SHUT: the spring closed main valve can only be opened by a pressure signal from the jet level sensor - if for any reason the pressure signal is lost, the main valve will close, shutting off the flow of fuel into the tank.  This ensures that overfilling the tank is not possible even if any part of the jet level sensor or signal hose were to fail.

The unique Wiggins jet level sensor does not have any moving parts to wear out and is thus extremely reliable.  The Wiggins non pressurizing system uses only external signal hoses, making JNX easy to install and maintain.  The JNX system is available in both direct and remote fill configurations.
