Magnetic Bearing Refrigerant Compressor

SmarTurbo is a group company focused on R&D, manufacturing and sales of high speed turbo blower, turbo compressor and vacuum pump. We have built the most comprehensive research and development system of high speed permanent-magnet synchronous motor, air bearing and magnetic bearing and aerodynamics for mass-production of turbo blower, turbo compressor and vacuum pump.

Magnetic bearing refrigerant compressor, which is also called maglev refrigerant compressor, is the most advanced and energy-saving compressor used in cooled water chiller and heat pump by adopting magnetic bearing to levitate the rotor shaft, eliminating physical contact, which provides oil-free, frictionless operation.

Magnetic bearing refrigerant compressor is used for the industries:

Central Air Conditioning / Chillers: Mainstay air conditioning models for commercial buildings;

Data Center Cooling: PUE optimization, liquid cooling / air-liquid hybrid;

Industrial Process Cooling: Chemical, pharmaceutical, and electronics manufacturing;

Cold Chain Logistics / Cold Storage: Low-temperature storage and transportation, quick-freezing processing;

Heat Pumps / District Cooling and Heating: Industrial waste heat recovery, clean heating;

Emerging / Special Scenarios: Supercritical CO₂ cycle, ships, energy storage.

Magnetic Bearing Refrigerant Compressor Core Technology

Magnetic bearing refrigerant compressor consist of core technology of High Speed Impeller, High Speed Motor, Magnetic Bearing, High Speed Rotor, High Speed Rotor Coil and Volute.

High Speed Impeller

Air bearing turbo expander adopts design concept of three-dimensional flow impeller, which improves impeller efficiency up to 95%,realizes wide operation range, and volume flow

adjustable from 45% to 100%.

High Speed Motor

Permanent magnet synchronous motor is with electromagnetic efficiency up to 98%, wide range of high efficient operation, directly-driven loading, and without transmission loss.

Magnetic Bearing

Magnetic bearing is designed for complex operating conditions like high speed, extreme temperature, large loading and strong vibration.

High Speed Rotor

Variable frequency and speed control is good for the motor rotating in maximum speed of 200000 rpm.

High Speed Rotor Coil

Class H insulation is adopted to make the motor has high reliability and durability even operating in high temperature, strong corrosion and current shock.

Volute

High efficient aerodynamic design ensure good aerodynamic performance of blade and low aerodynamic noise, which help satisfy high pressure ratio, high efficiency and large flow aerodynamic performance.
