Industry Awards & Official Recognition
· 2015: 3rd Place, Tianjin Innovation & Entrepreneurship Competition (Yunchuang Space Cup)
· 2019: Recognized as an Outstanding Supplier to the Petrochemical Industry by the China Equipment Management Association
Our localized retrofit solution for horizontal solid-bowl scroll decanter centrifuges was featured in the 2026 National Recommended Catalog of Domestic Innovative Equipment for Energy
· & Chemical Industries. This innovation solved critical transmission bottlenecks for PVC centrifuges, boosting production capacity by 12.5% with official certification from the China Equipment Management Association.
· 2026: Our Large-Scale Resin Pellet Centrifugal Drying System obtained official technical appraisal certification from the Tianjin Science & Technology Innovation Development Center. This domestic alternative delivers strong import substitution value and broad commercialization potential for matching industrial processing lines.
Core Product Lines
Horizontal Solid-Bowl Scroll Decanter Centrifuges
We offer a complete lineup of 20 standard models ranging from LW230 to LW1100 to accommodate diverse processing demands.
· Our LW1100 and LW650 decanter centrifuges were certified as top-tier domestic equipment by the Tianjin Science & Technology Commission back in 2009.
· The fully sealed LWMF740×2220-D centrifuge was submitted by a major central state-owned enterprise in Jiangsu as a landmark domestic substitution project under Sinopec Group headquarters.
· We provide full overhaul, maintenance and modification services for all imported centrifuges, especially large-format units. Post-retrofit equipment delivers drastically improved operational stability, lower vibration and higher throughput.
Vertical Scroll Sedimentation Centrifuges
We manufactured core rotor assemblies and differential gearboxes for the 500-series vertical centrifuges supplied to a major central state-owned enterprise in Beijing. We are also developing the new LLFM760×2170-N vertical centrifuge, engineered specifically for separating specialty materials such as polyoxymethylene (POM).
Differential Gearboxes, Gear Reducers & Speed Increasers
We supply over 30 variants of centrifuge-specific differential gearboxes and more than 10 types of gear reducers / speed increasers for polymerization reactors to chemical and soy protein manufacturers nationwide. Our full-service package covers custom fabrication, routine maintenance, major overhauls and spare parts supply, earning consistent trust from our industrial clients.
Centrifugal Drying Systems – Landmark Domestic Substitution Breakthrough
· Our 12-ton-per-hour resin pellet centrifugal dryer has operated reliably in industrial facilities for years.
· The 50-ton-per-hour large-capacity centrifugal dryer was successfully delivered in 2024 as a flagship domestic substitution project approved by Sinopec headquarters. We secured three additional full-set orders in 2025, with units exported to the Middle East. This milestone ended China’s long-term reliance on foreign-manufactured drying equipment in this field.
· Today, Promising acts as an official supporting supplier for multiple domestic extrusion & pelletizing system manufacturers, solidifying our top-tier domestic capability to design and produce large-scale centrifugal drying equipment.
Future Outlook
Promising will maintain sharp market awareness to navigate competitive industry challenges, continuously advancing technical standards and internal operational excellence. We remain committed to delivering premium products and reliable after-sales service to global partners, and strive to create lasting industrial value for our stakeholders and society at large.
