What Nanjing CIGU Technology does

Nanjing CIGU Technology (南京磁谷科技股份有限公司), founded in 2006 and listed on the Shanghai Stock Exchange (ticker 688448) in 2022, is a Chinese industrial equipment manufacturer specializing in magnetic levitation fluid machinery. The company designs and produces five core product lines — magnetic levitation centrifugal blowers, magnetic levitation air compressors, magnetic levitation chillers, magnetic levitation vacuum pumps, and magnetic levitation turbo expanders — based on proprietary five-degree-of-freedom electromagnetic bearing technology, high-speed (up to 42,000 rpm) permanent magnet synchronous motors, three-dimensional flow impeller designs, and proprietary multi-level protection systems with self-power generation safe shutdown. CIGU operates an integrated 'Cigu Cloud' (磁谷云) remote monitoring platform that enables real-time equipment telemetry, intelligent frequency conversion control, and remote diagnostics.

The company serves industrial customers across municipal wastewater treatment, textile and dyeing, petrochemical, pharmaceutical and food, cement, leather and paper, dairy, and automotive manufacturing — selling primarily to energy-intensive process applications where traditional Roots blowers, screw compressors, water ring vacuum pumps, and chillers account for significant operational cost. Documented energy savings versus legacy equipment range from ~20% (compressors) to 50%-75% (vacuum pumps), with material noise reduction and near-elimination of mechanical maintenance. CIGU sells through a factory-direct enterprise sales model with technical sales engineers delivering customized on-site solutions, supported by application-specific case studies and participation in major industry exhibitions. The customer base includes state-owned utilities, large multinationals (Sinopec, Wanhua, Hengli, APP, Mengniu, Yili), and listed domestic manufacturers. Production capacity is approximately doubling with a new 35,000+ sqm facility that came online in June 2025, and recent JVs with Bitzer China and Yipuji Data Technology extend the company into refrigerant compressor and data center cooling verticals.

Used for municipal wastewater aeration, industrial wastewater treatment, and process air applications in cement, petrochemical, and pharmaceutical industries.
• Magnetic Levitation Air Compressor (磁悬浮空气压缩机) Two-stage compression, interstage cooling, ternary flow impeller design delivering 100% oil-free, CLASS 0 certified compressed air with approximately 20% energy savings versus traditional compressors. Sold to textile and dyeing, pharmaceutical fermentation, petrochemical, and food industry customers.
• Magnetic Levitation Centrifugal Chiller (磁悬浮冷水机组) Self-developed refrigeration equipment using magnetic levitation core technology with IPLV of 11.2, energy savings of 30%-50% versus traditional chillers, oil-free operation, lower noise, and easier maintenance. Designed for industrial cooling and HVAC applications.
• Magnetic Levitation Vacuum Pump (磁悬浮真空泵) Magnetic levitation bearings enable rotor stable suspension, high-speed inverter drives the impeller for continuous gas compression, eliminating bearing friction in water ring vacuum pumps. Delivers 100% oil-free and water-free operation with lower noise and vibration, used for paper formation, vacuum dewatering, vacuum pressing, and black liquor evaporation in paper and leather mills.
• Magnetic Levitation Turbo Expander Generator Set (磁悬浮膨胀发电机) ORC (Organic Rankine Cycle) power generation using magnetic levitation technology. Low-boiling-point organic working medium absorbs heat to produce steam, expands in turbine to generate power. Covers 100kW to 1000kW power ratings in a standard containerized skid-mounted structure for waste heat recovery.
