Desiccant Cartridge Dryer at NeoPhotonics: Stable -40°C Pressure Dew Point
NeoPhotonics is a well-known developer and manufacturer of photonic integrated circuits and high-speed optical components for communications networks. Optical and photonics manufacturing is highly sensitive to contamination. Moisture in compressed air can leave residue on precision surfaces, disturb coating and assembly processes, and cause pneumatic and automation equipment to malfunction, all of which can affect yield and product consistency.
To meet this need, BITEMAN supplied NeoPhotonics with its desiccant cartridge dryer. Using adsorption drying with a compact modular cartridge design, the dryer removes moisture from compressed air and delivers a stable pressure dew point of -40°C. This gives the facility a continuous supply of dry air, reducing moisture-related defects and unplanned downtime.
Highlights
With 20+ years of expertise in compressed air drying and purification, BITEMAN delivers dependable air treatment solutions for photonics, optics and electronics manufacturers worldwide.

All-in-One Compressed Air Dryer at Ningbo Sunpu LED: Stable -40°C Pressure Dew Point Ningbo Sunpu LED is a leading LED manufacturer. In LED production, compressed air is used in packaging, cleaning, drying, dispensing and automated equipment. Moisture in the air can lead to condensation on components, corrosion, unstable equipment performance and lower product yield, so a dry, stable air supply is essential. To meet this need, BITEMAN supplied Ningbo Sunpu LED with its all-in-one compressed air dryer. The unit combines refrigeration, adsorption and filtration in one compact system, removing water, oil and particles while delivering a stable pressure dew point of -40°C. The result is a continuous supply of dry, clean air for production, with lower risk of moisture-related defects and unplanned downtime. Highlights Stable -40°C pressure dew point, meeting the plant’s air quality requirement Three-in-one design: refrigeration, adsorption and filtration in a single unit Compact, easy to install and maintain With 20+ years of expertise in compressed air drying and purification, BITEMAN helps manufacturers worldwide keep their air dry, clean and reliable.

Case Study: Wuxi Huayu Optoelectronics – BITEMAN Mold-Core Air Dryer Reliable Compressed Air Drying for Optoelectronics Manufacturing In the optoelectronics industry, precision manufacturing processes require clean, dry and stable compressed air. Moisture contamination can affect pneumatic equipment, process stability and the reliability of precision production operations.

All-in-One Compressed Air Dryer at a Chemical Enterprise: Stable -40°C Pressure Dew Point Chemical production depends on clean, dry compressed air. Instrument air, pneumatic valves, conveying and process control systems all rely on it. Moisture, oil mist and dust in the air can corrode pipelines, cause instruments and pneumatic components to fail, and put production continuity and safety at risk.
