SinoCleansky CNG PRU (PRMS) 1000NM3/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. The popular type pressure regulating unit 1000 NM3/H are designed for 250 bar CNG to keep the flow rate of 1000 NM3/H and outlet pressure of 2-4 bar.

The outlet pressure is customized.


SinoCleansky’s CNG PRU 1000NM³/H is a high-performance Pressure Regulating Unit designed to bridge the gap between high-pressure CNG storage and low-pressure end-use. With a stable flow rate of 1000 cubic meters per hour, this unit efficiently reduces high-pressure CNG (20-25 MPa) to a safe, usable pressure range of 0.2-0.4 MPa—ideal for industrial gas supply, commercial heating, and municipal natural gas networks. As a one-stop CNG/LNG/NGV solution provider, we’ve integrated robust structural design with intelligent control features, ensuring easy integration into existing systems and minimal operational downtime. The unit’s compact layout and modular components also simplify on-site installation and maintenance, making it a preferred choice for clients seeking cost-effective and reliable pressure regulation.


Industrial CNG PRU


Core Performance Metrics

Flow Rate: 1000 NM³/H (consistent output under rated inlet pressure and temperature)

Inlet Pressure: 20-25 MPa (compatible with high-pressure CNG cylinders and storage tanks)

Outlet Pressure: 0.2-0.4 MPa (customizable to 0.1-0.6 MPa based on client end-use needs)

Design Temperature: -19℃ to 60℃ (adapts to cold and hot climates without performance loss)

Medium: Natural Gas (NG) (meets ISO 13686:2017 gas quality standards)


Structural & Safety Features

Two-stage pressure regulation: First-stage international brand regulator ensures primary pressure reduction; second-stage domestic high-precision regulator refines pressure stability.

Built-in safety protections: Over-pressure cut-off valve (triggers at 1.5x rated outlet pressure) and pressure release valve (vents excess pressure to prevent system damage).

Optional add-ons: Heat exchanger (prevents temperature drops during decompression), mass flow meter (for accurate gas consumption tracking), and PLC+HMI control panel (enables remote monitoring).
