Product Model & Qualification Clarification

Real Product Model System (DW Series)

Our in-house brand Chiencheng uses the unified DW series model naming; no other model prefixes exist. Verify line by line in the product center:

• Upright ultra-low freezers: DW-L28 ~ DW-L938 (-25 ~ -86°C, 28 ~ 938L)
• Chest ultra-low freezers: DW-W60 ~ DW-W620 (-15 ~ -80°C)
• Deep-cold upright models: DW-60W70 ~ DW-60W1000 (down to -150°C)
• -150°C deep cryogenic freezers: DW-W58 ~ DW-W600 series (e.g., DW-145W58)

Qualification Nature: Class II Medical Device Business Filing (Not a Product Registration Certificate)

We hold a Class II medical device business filing certificate, which is a business qualification proving we are authorized to sell Class II medical devices. It is NOT a medical device product registration certificate. Whether a device is a medical device depends on whether that model separately holds a product registration certificate, verifiable via the NMPA website. Our official website and channels never mark unverified product registration numbers.
