Ultra Fast Fill System

Faster CNG transfer through a matched flow path

The Ultra Fast Fill System improves transfer performance by optimising the flow path between storage, priority panels, dispensers and the vehicle or trailer interface.

Ultra Fast Fill System®

Faster CNG flow through purpose-built, matched components

The Oasis Ultra Fast Fill System® improves transfer performance by optimising the flow path between storage, priority panels, dispensers and the vehicle or trailer interface.

Oasis CNG & Hydrogen Ultra Fast Fill System

See the ultra-fast difference

CNG and hydrogen transfer performance is often constrained by restrictions, heat build-up and inconsistent flow through the system. These limitations reduce fill speed, lower delivered volume and affect overall station efficiency.

By reducing restrictions, controlling temperature, and improving flow consistency, the system enables faster fills, higher transfer efficiency, and enhances performance.

What changes with ultra-fast fill

Higher flow capacity

Optimised bore sizes and internal geometries reduce restriction, allowing higher gas volumes to move more efficiently through the system. This improves transfer rates while maintaining pressure through the critical flow path.

Controlled temperature

Heat build-up during transfer limits how much gas can be delivered. By reducing turbulence and restriction, the system helps control temperature rise and supports fuller, more efficient fills within safe operating limits.

Faster turnaround

Improved flow and temperature control reduce fill times. Vehicles spend less time at the dispenser, increasing station throughput and supporting higher utilisation.

Ultra-fast fill is a complete system approach

Ultra-fast fill performance is achieved by designing the transfer path as a connected system. This includes:

  • Tank head valves
  • Ball valves
  • Manifolds
  • Breakaways
  • Couplers and nozzles

Each component is engineered to work together, maintaining consistent flow, minimising restriction and supporting stable performance across the system.

Frequently Asked Questions

Our Ultra-Fast Fill System is a high-pressure gas-transfer approach focused on maximising flow, controlling temperature, and reducing restrictions across the transfer path. It considers how the components work together to improve overall transfer performance.

Fill times are reduced by increasing flow capacity and limiting temperature rise during transfer. This allows gas to move more efficiently into the vehicle and improves overall transfer speed.

As gas is transferred, temperature rises due to compression and turbulence. Higher temperatures reduce the amount of gas that can be delivered. Controlling temperature helps improve fill completeness and transfer efficiency.

No. Pressure alone does not solve flow restriction or temperature issues. Ultra fast fill depends on improving the flow path and reducing the losses that slow transfer.

In many cases, yes. Performance improvements can often be achieved by upgrading key components and improving the transfer path without redesigning the entire system.

CNG and hydrogen gas transfer applications with high utilisation and frequent refuelling cycles benefit most, including fleet operations, bus depots, logistics hubs and high-throughput refuelling stations.

Components are designed to be serviced on-site using dedicated service kits. This allows maintenance to be carried out efficiently without removing major assemblies, helping reduce downtime and operational disruption.
