Description:

The super high speed air-bearing centrifugal air compressor is designed specifically for hydrogen fuel cell systems. It adopts an automotive-grade development process and quality standards and uses core components such as oil-free air bearings, permanent magnet synchronous motors and high-frequency silicon carbide drives. The company's core technologies include super high speed rotor platform technology (over 120,000 rpm, meeting a 500,000 start-stop life), high-efficiency compressor impeller and turbine aerodynamic design (isentropic efficiency above 80%, 5% higher than the industry), and variable-geometry turbine control technology.

HEC series two-stage serial compression air compressor: adopts high speed two-stage centrifugal compression technology, matching the needs of 5kW-200kW hydrogen fuel cell systems.

VSEC series single-stage compression with variable-geometry expander: while maintaining the high performance of the centrifugal air compressor, it adds an expander system with variable geometry, achieving the customer's target flow and pressure through single-stage compression, and recovering energy from stack exhaust gas through the variable-geometry turbine. The recovery efficiency can reach over 30%, particularly suitable for ultra-high power hydrogen fuel cell systems (120kW-300kW).

FAQ

Q1: Can you provide samples for testing?
A: Yes, we support sample orders for vehicle installation testing and performance verification, and also accept mixed-model sample orders.

Q2: What is the delivery lead time?
A: Sample orders usually take 15-30 working days; bulk orders are negotiated according to specific quantity and configuration requirements.

Q3: Is there a minimum order quantity (MOQ) limit?
A: There is no strict MOQ limit; 3-piece sample trial orders are supported, and bulk order prices are more favorable.

Q4: What is the difference between the HEC series and the VSEC series?
A: The HEC series uses two-stage serial compression for 5~200kW fuel cell systems; the VSEC series adds a variable-geometry expander on the basis of single-stage compression to recover stack exhaust energy, for 120~300kW systems, reducing power consumption by over 30%.

Q5: How does the air compressor connect to the fuel cell system?
A: The air compressor uses CAN 2.0B communication (250k/500kbps), a controller DC input of 250~750V and a low-voltage supply of 9~36V, and supports KL15 hardware wake-up.

Q6: How efficient is the air compressor?
A: The maximum system efficiency of the HEC series is >=71%~73%; the VSEC series with expander energy recovery has a maximum system efficiency of >=93%~95%.

Q7: How to handle product failures?
A: We implement a strict quality control system, with an out-of-factory defect rate below 0.2%. During the warranty period, small batches of defective products will be replaced with new ones in the next order; batch quality problems will be negotiated for repair or replacement to ensure customer rights.
