It has valid import/export licensing, six years of export experience, and exports 41%–50% of total sales, mainly to South America and Europe. The supplier reports flexible customization, five years of total R&D-engineer experience, and 41–50 quality-control staff, but has one production line and does not conduct continuous quantity reconciliation for each batch. Finished products are checked by packing staff. No SDK is available, while certification holdings, customer cases, after-sales capability, and several sustainability-related conditions are not evidenced. Financial records are referenced for 2021–2023, but the supplied information does not provide sufficient financial-performance detail for a credibility judgment.

Supplier typeThe supplier is a China-based limited company established in 2016, with a combined company type, an affiliated company, and business activities covering compressor design, production, sales, equipment maintenance, and related mechanical-electrical products. Its stated product range includes rotary screw, oil-free, centrifugal, scroll, and blower equipment.

R&D capabilityThe supplier reports five years of total R&D-engineer experience and describes efforts to improve compressor efficiency and reduce energy consumption.
