Import Dry Box, Cwdc1248b — Buy in wholesale FOB from Supplier in China

The Dry box, CWDC1248B is a passive dehumidification storage cabinet designed for precision instruments and sensitive materials. It features a 1.2mm cold rolled steel body with TIG welding and a sprayed coating, paired with 4mm tempered glass windows and a double-frame structure for structural integrity. The cabinet uses a microcomputer-controlled humidity system with Honeywell USA sensors and a digital frequency output port for compatibility with external monitoring systems. It maintains internal humidity without active components like fans or heaters, relying instead on shape memory alloy and PTC heating elements for dynamic moisture control.

This model operates without motorized components, eliminating noise and energy consumption while preventing condensation or counter-humidity effects. The internal environment remains dust-free and stable, with humidity rise limited to under 10% over 24 hours during power loss due to memory retention. The control system includes a triple LED display showing real-time temperature, humidity, and dynamic humidity levels. The movement mechanism uses South Korea-engineered plastic rated to 300°C, German sieves, and Swedish dual-memory alloy springs, ensuring over 30 years of operational life under continuous use.

The CWDC1248B is commonly used by laboratories, medical device manufacturers, and optical equipment suppliers to store cameras, microscope lenses, microbalances, and reagents requiring low-humidity conditions. Buyers typically source it for cleanroom environments or production lines where moisture-sensitive components are handled. The cabinet is supplied with a 2-year warranty and includes lifetime technical support for humidity-related guidance. Trade terms are FOB Shenzhen, with standard packaging in reinforced cardboard and foam inserts. MOQ is one unit, and lead time is typically 15 to 20 days after order confirmation.

Smtfly Electronic Technology is a manufacturer based in Fuyong Town, Shenzhen, Guangdong, China, specialising in passive dehumidification storage solutions for electronic and laboratory equipment. The company is verified as a harbor-tier supplier with no public data on headcount, annual revenue, or client list. Its product development focuses on reliability over marketing claims, with the CWDC1248B model reflecting a design philosophy prioritising durability and energy efficiency. The supplier does not claim certifications such as ISO or CE, and no third-party audit reports are referenced in the listing.

Response metrics indicate no recorded response rate or average response time, suggesting limited customer service engagement. The absence of trade assurance badges or certification logos on the listing implies the supplier operates on direct, transactional terms rather than platform-mediated guarantees.
