HEYI centrifugal air compressors
Oil-free magnetic-bearing compression for plant air systems
Magnetic suspended high-speed centrifugal air compressor packages for customers who need efficient, low-noise, low-vibration compressed air with intelligent control and reduced routine maintenance.
Product range
High-speed centrifugal compression with magnetic bearing support.
The HEYI platform uses a high-speed permanent magnet motor, active magnetic bearings and precision impellers. The result is a compact compressor package designed for oil-free air, simplified installation and digital operation.
Why HEYI
A cleaner operating profile for compressor rooms.
The magnetic-bearing platform is designed to reduce oil contamination risk, routine mechanical work and installation constraints while improving visibility of compressor performance.
Oil-free bearing system
No lubrication in the magnetic bearing support.
Active magnetic bearings support the rotor without mechanical contact, avoiding bearing lubrication and reducing routine mechanical maintenance to periodic filter replacement.
Low site impact
Low noise, no vibration and no heavy foundation.
The brochure states noise below 80 dB(A) measured one meter from the compressor, with no vibration and no foundation or anchor bolts required for typical installation.
Digital operation
PLC, touch screen, 4G and cloud monitoring.
The standard control platform records operating data, alarms and faults, with mobile or PC remote monitoring and interfaces for third-party systems such as ERP.
Operating principle
Two-stage or multi-stage centrifugal compression.
Gas is accelerated and pressurized by the impeller. In two-stage or multi-stage configurations, the air is compressed, cooled through an intercooler, then sent to the next impeller until the required discharge pressure is reached.
A high-speed permanent magnet motor directly drives the impeller, reducing mechanical transmission losses and supporting high efficiency over the compressor life.
Centrifugal compressor assembly with impeller, motor and bearing components.
Product structure
Integrated compressor package for fast installation.
The package integrates the compressor body, high-speed permanent magnet synchronous motor, inverter, controller, intake grille, inlet filters and motor cooling air path inside a compact enclosure.
Internal compressor package arrangement.
Compact blue cabinet package.
Catalog selection data
Model families cover low-pressure and higher-pressure air duties.
Final selection should be checked against the required site pressure, flow, cooling water condition, ambient design case and compressor control philosophy.
| Model group | Motor power | Discharge pressure | Capacity range | Typical note |
|---|---|---|---|---|
| HYMTC150-HYMTC600 | 110-440 kW | 0.15-0.4 MPa | 31-183 m³/min | Brochure table stated at 20°C, 1 atm and 60% relative humidity. |
| HYMTC400-HYMTC800 | 315-600 kW | 0.7-0.8 MPa | 53-111 m³/min | Higher-pressure catalog range with DN150-DN200 outlet sizes. |
Control platform
Remote visibility for operation, alarms and energy management.
The intelligent operation platform can visualize equipment status, monitor energy consumption, collect operating data, support gas-use analysis, manage compressors remotely and keep daily operation records.
Touch-screen control interface.
Cloud, gateway and multi-compressor monitoring architecture.
Core technology
Precision components for high-speed rotating equipment.
The brochure highlights 5-axis machined AL7075 aerospace aluminum impellers, high-speed permanent magnet synchronous motors, active magnetic bearings, position sensors and bearing protection logic.
- Magnetic bearing load capacity stated up to 10 kN radial and 20 kN thrust.
- Sensor signal quality stated for cable lengths over 300 m without impedance conversion.
- Class H insulation with temperature resistance up to 180°C.
Precision impeller design and aerodynamic verification.
Rotor, motor and magnetic bearing structure.
Cooling water requirements
Confirm site cooling water before final selection.
The buyer should provide qualified cooling water for compressor operation. The brochure specifies cooling water pressure of 0.2-0.4 MPa, temperature not above 35°C and flow of 40 tons per hour, with softened water or compliant industrial circulating water.
0.2-0.4 MPa
Cooling water supply pressure range.
≤35°C
Cooling water temperature stated in the brochure.
40 t/h
Cooling water flow stated for the compressor package.
Important: impurities or excessive hardness can block heat-exchanger passages or cause scale, reducing heat-transfer efficiency.
Applications
Built for continuous industrial air demand.
HEYI lists applications across wastewater treatment, biopharmaceuticals, flue gas desulfurization, aquaculture, petrochemicals, natural gas transportation, mining, metallurgy, power electronics, textile, paper making, casting and spraying.
Reference upgrades
Compressor replacement projects focused on energy and stability.
The brochure includes textile and fermentation upgrade examples where old screw or piston units were replaced by HEYI centrifugal air compressors to reduce energy consumption, noise and maintenance while improving system stability.
Reference compressor installations shown in the HEYI product brochure.
Pharmaceutical case
Six centrifugal units replaced ten piston machines.
The stated result was annual electricity savings over 4 million RMB, with no friction, no lubrication and reduced performance decay across the life cycle.
Textile case
One 210 kW unit replaced two existing compressors.
The stated result was annual electricity savings up to 280 thousand RMB, with lower noise and easier installation.
