1. Compressor Characteristic:
Flexible Application and Strong Adaptability

• ● It can reduce the impact of changes in natural gas composition.
• ● It is more suitable for natural gas compression with liquid or saturated water vapor.
• ● The main air end has strong corrosion resistance and high wear resistance, and can adapt to the situation of natural gas containing corrosive gas.
• ● The pressure of intake and exhaust can be used in a wide range (intake - 0.67 Bar (vacuum) to 17 BarG, exhaust 1.36 BarG to 35 BarG).
• ● Various driving modes can be selected, such as motor, diesel engine and gas engine.

• ● The on-site connection is convenient and simple. Users only need to connect the access interface, hose or hard pipe connection.
• ● No foundation is needed. The oil lubricated screw compressor runs steadily without pressure fluctuation. The flat ground can withstand the self-weight of the machine without concrete foundation and grouting.


Low Operating Costs


• ● It has high reliability and can run without fault all the year round.
• ● Less vulnerable parts, lower operating and maintenance costs than other types of compressors.


Strong Mobility


• ● Compressors can be installed directly on trucks or trailers to meet the needs of mobile work.
• ● The design of variable content area ratio (Vi) makes the compressor work at the optimum efficiency point under different working conditions, saves the daily operation cost and reduces the downtime risk.

2. Air End Characteristic:
Adopts oil lubricated gas screw compressor technology and mature natural gas application experience in the United States market, to manufacture oil lubrication natural gas screw compressor to meet the requirements of natural gas gathering and transportation.

3. CNG Oil Lubrication Screw Air Compressor:
Type: Oil lubricated screw air compressor
Design service life: At least 20 years, compressor air end is original imported from SULLAIR USA.
Noise does not exceed 89dB (A) at a distance of 1 meter from compressor unit.

Coupling and Protective Cover
The coupling transmission mode is adopted between the compressor and the driving machine.
All moving parts that may endanger personal safety are provided with protective shields.
Shield is made of sparkless material.

Performance Guarranty:
Compressor shaft power: +/-5%;
Compressor air delivery: +/-5%;
Compressor discharge pressure: no negative deviation.

A bypass control valve is installed between the inlet and outlet of the compressor to realize light load start-up and unloading functions.

The inlet of the compressor is equipped with pressure sensor, which is used for low pressure alarm and flow control.

The outlet of the compressor is equipped with a pressure sensor for display, setting and high exhaust pressure alarm.

All instruments are SI unit, pressure unit MPa, temperature C.
The company provides on-site primary instruments, including on-site pressure transmissions, liquid level transmissions, pressure gauges, differential pressure meters, thermometers, liquid level meters and PLC cabinets. All field instruments and control cabinets meet the explosion-proof standard dIIBT4.

All wiring of the compressor control system cabinet is completed in the factory.
Compressor flow and pressure control mode adopts variable frequency flow regulation mode to achieve constant exhaust pressure.
The PLC control cabinet and frequency converter of 3.6.4 compressor are installed in the safe area. The compressor is equipped with explosion-proof operation column.
