Description
Natural Gas Compression Solution for Energy and Process Systems
The DFW-5.3/3-15 Oil-Free Natural Gas Compressor is designed for industrial natural gas pressurization applications in LNG, petrochemical, environmental protection, and related process systems.
Using natural gas as the compression medium, the compressor provides a flow rate of 1100Nm³/h, with an inlet pressure of 0.3MPa.G and a discharge pressure of 1.5MPa.G.
Driven by a 90kW motor, the DFW-5.3/3-15 adopts a D-type balanced reciprocating piston structure with oil-free lubrication, helping maintain clean gas compression while providing stable operation for industrial applications.
The compressor is supplied with a skid-mounted configuration, integrating the main unit and supporting components for easier transportation and installation.

FAQ
1. What makes the DFW-5.3/3-15 different from conventional natural gas compressors?
The DFW-5.3/3-15 adopts a D-type balanced oil-free reciprocating structure with a two-stage double-acting compression design. Compared with conventional lubricated compressors, its oil-free compression chamber helps prevent lubricating oil from entering the gas stream, making it suitable for natural gas applications requiring cleaner gas handling.
2. Why is an oil-free design important for natural gas compression?
The oil-free structure uses PTFE self-lubricating packing and a separated lubrication system to reduce the risk of oil contamination during compression. This design helps maintain natural gas quality and is suitable for LNG, petrochemical, and process gas applications where gas purity is important.
3. What are the main operating parameters of the DFW-5.3/3-15 natural gas compressor?
The DFW-5.3/3-15 is designed for natural gas compression with a flow rate of 1100Nm³/h, an inlet pressure of 0.3MPa.G, and a discharge pressure of 1.5MPa.G. The unit is driven by a 90kW motor and supplied as a skid-mounted package.
4. What advantages does the D-type balanced structure provide?
The D-type balanced structure helps reduce vibration during reciprocating operation and improves mechanical stability. Combined with optimized cylinder arrangement and axial valves, it supports stable gas flow and long-term industrial operation.
5. Why is the DFW-5.3/3-15 supplied as a skid-mounted unit?
The skid-mounted design integrates the compressor and supporting components on a common base, which simplifies transportation, installation, and connection with customer process systems. It is suitable for industrial projects requiring compact equipment layout.
