Permanent Magnet Variable Frequency Screw Air Compressor
Permanent magnet era has arrived,DENAIR permanent magnet synchronous inverter compressor equipped with self-developed permanent magnet motor,after researching and overcoming technique for several years,listed glory and achieved the most reliability and peak effectiveness.

A.Permanent Magnet Motor
. Remain more than 96% efficiency under and load, Save energy 38% more than ordinary motor, Save energy 10% more than induction variable frequency motor .
. Use coaxial integration structure degine, No need to use transmission components such as belt,gear and shaft couoling,No transmion loss completely, Transmisson efficiency reaches 100%.
. Motor could start immediately after downtime .Don't influence motor's life with infinite start and stop. Starting current is less than 100% full load current .
. Set ratation to achieve maximum air volume according to different use pressure through wide range control .
. Permanent magnet variable frequency motor has the advantage of low rotation and high torque, so its variable frequency control model is wider than ordinary induction variable frequency motor.
. Permanent magnet motor's volume and weight are reduced by 30% and 35% compared to same power motor.
B.Fenquency Converters
. With the standard configuration of radio-frequency reactor,it effectively reduce the high frequency and magnetic field interference outdoor which is generated by inverter.
. Reliably bring down the peak point current while starting,realizing the soft starting and saving the cost of power supply equipments.
. With special design for radiating,it can avoid high temperature trip in summer .
. Standardly euipping with dust proof nets and processing the surface of circuit board in coating way, reaching the effect of antifouling, dustproof and moistureproof.Under the standard protocol of CAN, it is with the wire specification of hardware,great ability in resisting noise .
C. Display Screen
. Initial deta dispalying for energy saving,marking it visible for you .
. Multi protection design ,2cautions for light failure,10 alerts for heavy fault.
. three pressure units optional (Mpa/Bar/Psi).
. Automatic standby and dormancy awakening function.
. With the function of setting target pressure,realize the expected pressure value of the unit.
. Multiple nodes reserved for controlling air dryer's start-stop and preheat function .
. Dispaly language interchangeable between CN&EN,simplified chinese & Traditional Chinese character
D.Centrifugal Fan
. It can reach the optimum cooling effect in harsh environment .Double air intake centrifugal fan with high efficiency,large air flow low noise.
