SinoCleansky’s CNG PRU 2000NM³/H is a high-capacity Pressure Regulating Metering System (PRMS) engineered for large-scale CNG distribution networks—such as CNG mother stations, industrial parks, and power plants. With a flow rate of 2000 cubic meters per hour, this unit efficiently reduces ultra-high-pressure CNG (250 bar) to a safe, usable pressure of 2-4 bar, ensuring stable gas supply for high-demand applications. It features a two-stage pressure regulation design: the first stage uses international brand regulators for reliable primary reduction, while the second stage refines pressure to meet end-use needs. As a leading CNG/LNG/NGV solution provider, we’ve optimized the unit for durability (corrosion-resistant materials) and intelligence (optional PLC automatic control), making it a top choice in markets like Nigeria, Southeast Asia, and the Middle East.
SinoCleansky CNG PRU (PRMS) 2000NM3/H are manufactured under strictly quality control system with full set of inspection report.
CNG PRU are applied for regulating high pressure CNG to normal pressure, PRMS 2000 NM3/H are especially designed for 250 bar CNG to keep the flow rate of 2000 NM3/H and outlet pressure of 2-4 bar, or other pressure range.
This type of CNG pressure regulating metering system is popular in Nigeria and other markets.

Choosing the right CNG transport and dispensing equipment is essential for building a reliable virtual pipeline. This guide compares CNG tube trailers, MEGCs, and jumbo tube cascades, explaining how transport mode, payload capacity, site space, delivery frequency, and pressure management affect equipment selection. CNG tube trailers are suited to high-volume road transport, while MEGCs provide greater multi-modal flexibility. Jumbo tube cascades support efficient gas storage and dispensing at the destination. By matching equipment capacity with demand, site conditions, and regulatory requirements, project teams can improve logistics, control operating costs, and maintain a stable CNG supply.
