AI-Powered supplier vetting
SummaryThe supplier is a limited trading company with eight employees, focused on miniature refrigeration and thermal-management products, including miniature compressors, DC air conditioning, compact liquid chillers, and free-piston Stirling coolers. It holds a valid import and export license, exports approximately 90% of sales, and serves domestic, East Asian, European, and North American markets. Stated production volumes are substantial across several product categories, but the supplier’s organizational scale and service infrastructure appear limited. It offers flexible customization but does not provide SDKs, ODM services, or OEM services for popular brands, and reports no new products in the past year. Service procedures exist for corrective actions and customer complaints, but written records are unavailable; no overseas service countries are identified. Financial data is only represented by years, without financial performance figures, so credibility cannot be assessed. No certifications or customer...
Supplier typeThe supplier is identified as a trading company and a limited company, with no larger corporate-group affiliation. It has eight employees and a valid import and export license, indicating a legally registered, independently operated trading entity rather than a stated manufacturing-group subsidiary.
After-Sales capabilityThe supplier has procedures for corrective and preventive actions and customer complaints, but no written records are maintained. It reports zero countries offering overseas services and only one qualified service-capability supplier, indicating limited documented and international after-sales support.
R&D capabilityThe supplier describes itself as a miniature compressor innovation leader and offers flexible customization, but it has no available SDK, reports no new products in the past year, and does not provide ODM services. The evidence supports product-domain positioning but not strong current innovation output or development infrastructure.
Production capacityThe supplier offers multiple refrigeration products and reports annual outputs of 50,000 condensing units, 30,000 free-piston Stirling cryocoolers, 50,000 custom cooling systems, 50,000 compact liquid chillers, and 100,000 DC compressors. These stated volumes indicate established supply capability, although the company has only eight employees and is classified as a trading company, so the underlying production ownership is not clarified.
Customization capabilityThe supplier explicitly provides flexible customization and lists custom cooling systems among its offerings. However, it does not provide ODM services, so customization is supported but does not extend to the stated ODM model.
Product Q&A
Q:What is a DC Mini Compressor?
A:
A DC mini compressor is a small, electrically powered compressor that operates on direct current (DC), typically 12V, 24V, or 48V. It is commonly used in portable refrigeration, medical cooling, automotive air conditioning, and compact cooling applications.
Q:What are the advantages of a DC Mini Compressor?
A:
Compact Size: Suitable for tight spaces. Energy Efficient: Uses only the required power, often with variable speed control. Low Noise & Vibration: Quieter than traditional AC compressors. Low Starting Current: Works well with battery-powered or solar applications.
Q:What applications use DC Mini Compressors?
A:
Portable refrigerators & freezers (camping, RVs, medical transport). Automotive cooling systems (car mini air conditioners). Medical cooling (vaccine storage, insulin coolers). Electronics cooling (laser systems, high-performance computing). Small chillers & lab equipment.
Q:What power sources can be used for DC Mini Compressors?
A:
Batteries (Lithium-ion, Lead-acid). Solar panels (common in off-grid cooling applications). Vehicle alternators (for mobile refrigeration). AC-DC power adapters (for stationary applications).
Q:How is speed controlled in a DC Mini Compressor?
A:
Most DC mini compressors use a PWM signal, 1-5V analog signal, or UART communication to adjust speed. Higher speeds increase cooling capacity, while lower speeds reduce power consumption.
