Description

High-Pressure Compression Equipment for CNG Refueling Systems

The ZF-0.12/(30-200)-250 CNG Piston Compressor is designed for high-pressure natural gas compression in CNG filling stations and related gas storage systems.

Unlike conventional natural gas compressors used for general gas transportation, this unit focuses on increasing natural gas pressure for CNG refueling applications.

The compressor handles natural gas with a flow rate of approximately 400Nm³/h, supports a wide inlet pressure range of 3.0~20.0MPa.G, and delivers compressed gas up to 25.0MPa.G.

Equipped with a 30kW explosion-proof motor, the compressor adopts an oil-free reciprocating piston structure, providing a suitable solution for CNG stations requiring clean gas compression.

CNG Station Compression Process

In CNG filling stations, natural gas needs to be compressed before storage or vehicle refueling.

The ZF-0.12/(30-200)-250 is mainly used for:

Natural Gas Vehicle Refueling Stations

The compressor increases natural gas pressure for CNG vehicle filling operations.

CNG Storage Systems

Suitable for systems where natural gas needs to be compressed and stored at high pressure.

Gas Transfer and Distribution Applications

Used in gas systems requiring high-pressure natural gas transfer.

Small and Medium CNG Facilities

The compact compressor package is suitable for projects with limited installation space.

Oil-Free Compression Design for CNG Applications

The ZF-0.12/(30-200)-250 adopts an oil-free piston compression design.

The compression chamber is separated from the oil lubrication system, helping reduce the possibility of lubricant entering the compressed gas.

Main characteristics include:

Oil-free compression structure
Reciprocating piston technology
High-pressure sealing system
Natural gas purity protection

This design is suitable for CNG applications where clean compressed gas is required.

Wide Pressure Adaptability for Different Gas Supply Conditions

CNG stations may receive natural gas from different supply conditions.

The ZF-0.12/(30-200)-250 is designed with a wide inlet pressure range from 3.0MPa.G to 20.0MPa.G, allowing it to adapt to different upstream gas pressure conditions.

The compressor can provide stable high-pressure natural gas output without changing the main compression configuration.
