With a deep commitment to the global market, Shanghai Dengsheng Instruments has earned international acclaim for its quality.








A Class 100 cleanroom oven, also known as a Class 100 clean oven or Class 100 clean drying oven, is a specialized piece of equipment integrating high-temperature drying and cleanroom environmental control. Through a HEPA high-efficiency filtration system and directional airflow organization, the working chamber achieves ISO Class 6 (formerly Class 100) cleanliness standards. The equipment employs laminar flow vertical or horizontal air supply modes. Clean hot air is filtered by the top FFU unit (filtration efficiency ≥99.99% for 0.3μm particles) and then evenly covers the working surface. It is also equipped with an automatic air shower purification module to ensure rapid restoration of cleanliness when the door is opened. The temperature control range covers 50-300℃, with a fluctuation of ≤±1℃. It is suitable for drying processes sensitive to particulate contamination in precision manufacturing, primarily used in the electronics, electrical engineering, integrated circuit, COB black glue drying and curing, display screen, chip, LCD, CMOS, IS, and pharmaceutical industries. It can also be used for high-temperature testing with high environmental cleanliness requirements. It is an essential piece of equipment for drying, heat treatment, thermal aging, high-temperature testing, and curing of items in these industries.
