Note:
Standard voltage is 380V/50HZ/3P, other voltage is available.

The recommended best capacity range is 60%-100%.
In cases of elevated altitudes, extreme temperatures, excessive humidity, heavy dust exposure, or any other challenging operational environments, we can offer tailored product designs to meet your specific needs. Customization is available to align with your unique requirements.

Rotor

The high-speed rotor is dynamically balanced, and designed to resist vibration without thrust bearings. There is no relative sliding in the rotor transmission, and the gear drive system is highly reliable, with a design life of 35 years.

Rotor

Impeller

● Aviation class high efficiency and high reliability titanium alloy impeller
● Anti-corrosion special coating impeller used for high corrosion industry
● Five-axis precision machining forging 3D flow back leaning design impeller, higher aerodynamic efficiency
● Splitter blade design for large flow
● Low flow loss and better adaptability for off-design conditions

Impeller

Bearings

● Tilting pad journal bearing realize high-speed and stable operation. Pad tilt will self-adjust when the bearing load changes.
● CC pad of high heat conductivity and high strength can decrease the bearing temperature and promote the stability of the rotor system.

Bearings

Highly Reliable Cooler

●  Straight tube design, no need to be pull out when maintaining, 90% maintenance time saved;

● No consumption parts and low maintenance fee;

● Larger design, high heat exchange efficiency, low water consumption and low pressure loss, about 1-2% energy saving;

● Gradual changing Cross design, perfect gas-liquid separation effect; ●  Stainless steel backing board design, eliminating corrosion risk;

● No fastening parts, no risk of dameging the impellor by fallen parts; ●  Supported by both side, eliminating the damage risk from resonance; ●  Long life span drainer, no rusty, draining strongly and zero gas consumption.

Highly Reliable Cooler

Gear Box

Horizontal split type for easy maintenance of the bearings and shaft seals.

Thrust collar instead of thrust bearings. Which makes the structure simpler and increase the transmission efficiency and reliability.

Gear Box

Local Control System

● The advanced Siemens PLC system +7” touch screen, friendly interface and easy opeartion;

● Options for auto dual, constant pressure control and self-balance control mode;

● All operating parameters can be displayed and setted；

● Features for various alarm and trip condition；

● Features anti-surge and surge prediction functions；

● Communication to DCS by DH+, Modbus, Profibus OR Ethernet.

 

Local Control System

Inlet Guide Vane

The efficiency of compressor with IGV is 7-9% higher than that with butterfly valve, for IGV provides preswirl flow to the air taken into in the same direction as the impeller. Furthermore IGV can provide wider turn down rage and which is more smoothly during the adjusting period.

● Smoothly and high efficiency when adjusting;

● More safety and dust proof with cover;
● High reliability by fork type.

Inlet Guide Vane

Air Seal

The gas & oil seal is labyrinth type, which has no contact to the shaft., no abrasion, long life, and low maintenance, no consumption of instrument air, and also, horizontal split makes easier maintenance.
