UNITED OSD has a series of screw compressors with power ranging from 5.5 to 630kW, FAD from 0.69 to 120m3/min, and a pressure range of 0.2 to 1.5MPa. At UNITED OSD, we also provide services such as air compressor station design, manufacturing, operational training, energy-saving technical improvements, and customized types. The philosophy of wholeheartedly serving customers makes our progress steady and far-reaching.
UNITED OSD single-stage variable frequency screw air compressor UD-VFD series adopts vector control technology, ensuring low motor temperature rise and obtaining suitable torque over a wide speed range, driving the air compressor to operate stably. Vector control technology separately controls the excitation and torque vectors of the stator current, then synthesizes them and converts them into inverter parameter control signals to achieve full control over electromagnetic torque. This allows the motor to maintain low-temperature operation even at low speeds. This type of variable frequency technology can suppress the unavoidable noise and harmful harmonics in standard inverters. Adopting a new generation of proprietary vector variable frequency control, which converts DC to AC, improves high-temperature resistance, achieves higher conversion efficiency, saves energy consumption, and enhances reliability.
The UNITED OSD low-pressure series screw air compressor is a new type of compressor developed for energy saving, emission reduction, and environmental protection needs. It changes the traditional high-pressure compressor's method of supplying compressed air to air equipment after decompression, thereby saving energy. Currently, in the screw air compressor industry, the UNITED OSD's exhaust pressure can be as low as 1.2 bar, ensuring an exhaust oil content of less than 2ppm and providing clean and stable air supply. The enclosed cabinet with low-noise design is more environmentally friendly than piston compressors. Given that many industries do not require downtime, maintenance can be ensured during continuous operation; equipped with a fault alarm, it prepares users for emergencies, ensuring stable and reliable operation.

UNITED OSD two-stage fixed-speed screw compressors have a wide range of uses in industrial, manufacturing, and other applications. You can find them on offshore drilling platforms and in remote pipeline settings, where they are used to start engines and motors or assist in conveying drilling mud. They are also used to drive turbines and generators in power plants, as well as various processes in manufacturing facilities.
The UNITED OSD two-stage VPM screw air compressor uses a permanent magnet synchronous motor, requiring no excitation current, resulting in high efficiency and no reactive power loss. The two-stage compression speed is high, and after frequency conversion, the air supply pressure range is wide and stable. The most significant advantages are energy saving and high air output. The air intake volume is adjusted in real-time according to air demand, ensuring the air compressor operates more efficiently.
