Air Bearing Compressor for HVAC

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.

Air bearing compressor, which is also called air bearing levitation centrifugal compressor, is the most advanced and energy-saving compressor used in cooled water chillers and heat pumps for HVAC by adopting air bearing to levitate the rotor shaft, eliminating physical contact, which provides oil-free, frictionless operation.

Air bearing compressor is a new generation of compressor, which significantly improves efficiency and reduces maintenance compared to traditional screw compressor.

Air Bearing Compressor Core Technology

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

High Speed Impeller

Air bearing compressor 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.

Air Bearing

Air 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.
