New generation of high-efficient imported host machine

1. The most advanced spiral tooth type technology

2. New-type 5:6 asymmetrical rotator tooth type

3. Drawing uses leitz high-precision CMM measuring machine

4. Adopt top-level quality SKF taper-roller bearing imported with original packaging from Sweden

5. Relative power increases by more than 5%-10% in gas displacement when compared with that of ordinary machine model

Highly efficient permanent magnet synchronous motor

1. Permanent magnet synchronous motor (PM motor) adopts high-performance NdFeB permanent magnet which will not lose magnetism under 200℃ and its service life reaches as long as 15 years

2. Stator coil uses dizzy-resistant enameled wire specialized for frequency converter with outstanding insulating property and longer service life

3. Coaxially integrated structural design, the motor has no bearing structure with transmission efficiency reaching 100%

4. Fill grease at regular intervals for free, and bearing replacement at regular intervals for free

5. The motor has function of temperature protection (PTC/PT100)

6. The motor is of broad range of speed regulation, high precision and broader range of air flow regulation

7. The motor is of stable operation, low noise and small vibration

8. Special electromotor shell design can provide motor of IP23/IP54/IP65 protection grade

Intelligent control system

Initiated energy-saving data display makes it possible for you see energy conservation. Multiple protection designs with one light fault remind and ten severe fault protections, three pressure units can be freely chosen including functions of (Mpa/Bar/Psi) free standby, sleep resuming, and target pressure setting functions, which can realize reservation of output air pressure value reached by unit and to make it excess nodes to be used to control dryer starting and stopping and pre-heating functions.

Superior vector control performance

1. Motor and appearance design patent

2. The motor has superior performance of starting immediately after stopping, it can make indefinite starting and stopping while not affecting service life of motor

3. Starting current doesn’t exceed 100% full-load current

4. As permanent magnet variable-frequency motor has advantages of low rotating speed and high output, its variable-frequency control mode has been more extensively applied than ordinary inductive variable frequency

5. Volume of permanent magnet motor reduces by 30% when compared with that of motor of the same power, with its weight reduced by 35% and simpler maintenance.

Intelligent PID function

Function: prevent frequent loading and unloading of air compressor system when air consumption rapidly changes so as to lengthen service life of the system. Pressure PID regulation under its function is more sensitive and controllable, even if under situation with great air consumption, it can also prevent excess loading and unloading of air compressor. Energy wasted because it’s too late for air compressor to lower rotating speed when change of air consumption is great will be reduced.
