Oxygen Booster System

The oxygen booster system raises low-pressure oxygen to high pressure for filling, storage, and dedicated process requirements. The booster section is oil-free, and an isolation chamber separates the drive and booster sections to eliminate the risk of oxygen contamination by lubricating oil.

Gas Booster System

The gas booster system covers a wide pressure range and is compatible with multiple working media. It supports gas filling, gas recovery, leak testing, and other aerospace processes. The system provides smooth pressurization, pressure stabilization, and controlled depressurization for different pressure ratings and operating conditions.

High Pressure Processing

HPP technology draws its inspiration from the Mariana Trench, where water pressure reaches 110MPa at depths of nearly 11,000 meters, creating an environment in which very few microorganisms can survive. Inspired by this natural phenomenon, scientists developed a non-thermal pasteurization process that subjects food to pressures of up to 600MPa at low temperatures. Under these conditions, the cell membranes of pathogenic and spoilage microorganisms are disrupted, while the food’s natural nutrients, fresh flavor, texture, and appearance are preserved. Unlike conventional thermal processing, HPP eliminates discoloration, flavor deterioration, and nutrient loss caused by heat.

H₂ UAV Refueling System

The HiFluid Hydrogen UAV Refueling System is a self-developed hydrogen compression and refueling solution specifically engineered for hydrogen-powered unmanned aerial vehicles (UAVs). Driven directly by an explosion-proof servo motor, the reciprocating piston compressor provides precise control of both hydrogen pressure and flow, effectively addressing the challenge of hydrogen refueling for UAV operations in remote locations and environments without permanent hydrogen refueling stations.

H₂ Compressor for H₂ Refueling

HiFluid independently developed Hydrogen Compressor for Hydrogen Refueling utilizes high-pressure hydraulic oil to directly drive the piston for hydrogen compression. This achieves complete physical isolation between hydrogen and hydraulic oil, eliminating any risk of oil contamination. The system delivers an output pressure of 45-100MPa and features exceptional sealing performance, stable operation, flexible start-stop capability and easy maintenance, it is widely applied in scenarios such as green hydrogen production, hydrogen refueling and hydrogen components testing.
