Core Technology

Impeller

The impeller adopts the optimization technology of CFD calculation + neural network + genetic algorithm to optimize the parameters under a wide range of working conditions to achieve high efficiency of both rated and partial load.

Permanent Magnet Synchronous Motor

Permanent magnet synchronous motors are smaller in size and 10% more efficient than traditional asynchronous motors;

High-efficiency permanent magnet synchronous motors with 97.5% efficiency at full load and 95% efficiency at partial load;

H-class insulation design with a maximum temperature resistance of 180°C and high reliability.

XINLEI Horizontal Opposed Compressor

Direct drive design eliminates transmission losses, achieving 100% transmission efficiency;

The impellers are horizontally opposed, with more than 90% of the axial thrust canceling each other out, providing good self-balancing and greatly increasing the safety margin of the thrust bearings;

Compared with series-connected compressors, vibration is low and critical speed is high, making it more suitable for high-speed operation with high pressure ratios and higher reliability.

Machine structure

Air-cooled refrigerant cooling inverter

Refrigerant cooling provides significantly better heat dissipation than water cooling, resulting in higher cleanliness of electrical components and longer service life compared to water-cooled inverters. It eliminates the clogging issues associated with water cooling, greatly reducing the likelihood of unexpected downtime;

Fully closed-loop intelligent temperature and humidity thermal management system with active and precise refrigerant control;

Utilizes multi-objective PI control for flow and temperature difference to achieve high-load heat dissipation and anti-condensation functionality, further enhancing product reliability and applicability.

Industrial-grade Magnetic Bearing Technology

Radial and axial integrated modular design, compact structure, stable performance;

No lubricating oil required, zero friction, low power consumption, only 3-10% of conventional oil bearings, and the higher the speed, the more obvious the energy-saving effect;

Stable and reliable, magnetic bearings can withstand continuous violent surge of compressors for a long time without falling.

Bearing Controller

Utilizes high-precision components and a rational layout for high control accuracy and strong anti-interference capabilities, and has passed third-party EMC testing;

Integrated into the compressor, it uses temperature field simulation design for precise cooling, eliminating the risk of condensation and ensuring long-term reliability.

IOT Technology

The cloud platform can record and provide the operating status and operating parameters of the wind turbines bound to the platform, as well as perform fault alarm and data recording analysis. Users can log in to the platform to realize remote monitoring and energy-saving settings management, enabling users to realize real-time equipment management. At present, the IoT cloud platform provides ANDRIOD, IOS, and PC clients, and open interfaces to link with third-party software such as ERP, providing users with more possibilities.
