Import Cng Station Cascade System For Cng Storage — Buy in Bulk from Supplier in China

The CNG station cascade system from Wuxi Banner Vessel Co., Ltd. is a high-pressure storage and transfer assembly designed to replenish smaller CNG cylinders at refueling stations. It operates at pressures up to 250 bar, with a standard configuration of 6 to 12 steel cylinders arranged in sequential pressure banks to optimize gas flow and minimize compressor runtime. The system includes pressure regulators, manual and automatic shut-off valves, and a centralized control panel with pressure gauges and safety interlocks.

The cylinders are constructed from seamless 34CrMo4 alloy steel, conforming to ISO 11439 and DOT 4BA standards, with wall thicknesses calibrated for 250 bar working pressure. Typical working temperature range is -40°C to 65°C, and each cylinder is hydrotested at 1.5 times the rated pressure. The system does not include compressors or dryers - these must be sourced separately. The cascade design reduces energy consumption by 20% to 30% compared to direct compressor filling by leveraging stored pressure gradients.

This system is purchased by private CNG refueling operators, fleet maintenance depots, and municipal transit agencies in Asia and Eastern Europe. Units are shipped disassembled for container transport, with each cylinder secured in a steel frame and packed with foam padding. Standard packaging is for FOB Shanghai or CIF port of destination. Lead time is 6 to 8 weeks after deposit. MOQ is one full system. All components are marked with batch numbers for traceability.
