The Edwards nXDS dry scroll pump is a next - generation oil - free dry scroll pump. It boasts exceptional pumping capability and ultimate vacuum performance, and is equipped with state - of - the - art design features, making it a top - performing pump in its class.
Compared with traditional pumps, it has higher pumping speeds, lower ultimate pressures, lower power consumption, and less noise. The gas ballast function enables it to pump condensable vapors, including water, solvents, dilute acids, and bases. It adopts the latest tip - seal technology, which significantly extends the time interval between tip - seal replacements.
The integrated inverter drive with automatic voltage input sensing provides globally optimized pumping performance. The pump is designed to be fully field - serviceable, with intelligent control functions and a service interval of up to five years, reducing the cost of ownership.
There are different models of nXDS pumps, such as nXDS6i, nXDS10i, etc. The nXDS - C model is a modified version, suitable for vapor - handling processes and some applications involving corrosive substances, with Chemraz internal valves and stainless - steel fittings for extra protection. The nXDS - R model has the gas ballast blanked off, which is suitable for applications such as rare gas recirculation or gas recovery.
With a noise level as low as 52 dB(A), it creates a better working environment. Its vacuum enclosure is lubricant - free and hermetically sealed, ensuring a clean and dry vacuum and preventing cross - contamination. It also has an advanced interface that supports various control methods, such as remote control via USB, RS232, or RS485. It is widely used in fields like electron microscopy, surface science, and gas recovery.
The Edwards nXDS dry scroll pump finds extensive application across various industries and research fields, thanks to its clean, efficient, and reliable vacuum performance:
- Laboratory and Research: Ideal for analytical instruments such as mass spectrometers, electron microscopes, and surface science equipment. Its oil-free design prevents contamination, ensuring accurate results in sensitive experiments involving sample analysis or material characterization.
- Semiconductor and Electronics: Used in processes like thin-film deposition, wafer handling, and plasma etching. The pump's ability to maintain high vacuum cleanliness and stable pressure helps protect delicate semiconductor components from pollution, ensuring consistent production quality.
- Medical and Pharmaceutical: Applied in medical device manufacturing (e.g., vacuum packaging for sterile tools) and pharmaceutical research (e.g., freeze-drying of drugs). Its oil-free operation and capability to handle vapors make it suitable for environments requiring strict hygiene and purity.
- Industrial Coating: Supports vacuum coating processes for optics, automotive parts, and decorative items. By providing a clean, low-pressure environment, it ensures uniform coating adhesion and quality.
- Gas Recovery and Rare Gas Handling: The nXDS-R model, with its gas ballast blanked off, is well-suited for rare gas recirculation or gas recovery systems, aiding in efficient resource reuse and cost reduction.
- Environmental Analysis: Integrated into systems for air and water quality testing, where precise vacuum control is necessary to isolate and analyze trace contaminants.
Its versatility, combined with features like low noise, intelligent control, and long service intervals, makes it a preferred choice for applications demanding both performance and reliability.
