Desiccant Cartridge Dryer at Shennan Circuits: Stable -40°C Pressure Dew Point
Shennan Circuits is a leading manufacturer of printed circuit boards (PCBs) and related electronic products. PCB production uses compressed air throughout the process, including cleaning, blow-drying, pneumatic equipment and automated handling. Moisture in the air can leave water spots on boards, cause oxidation, and disrupt pneumatic equipment, directly affecting yield and consistency.
To meet this need, BITEMAN supplied Shennan Circuits 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 plant 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 PCB 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.
