Wiggins Non Pressurized Fast Fuel Systems

Wiggins JNXThe 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. JNX offers top-line quality, performance, and reliability at a competitive price.



The Wiggins 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.
