Smart VSD Screw Compressor

High-quality parts are applied to realize
high durability and reliability

The motor shaft is separated from the gearbox load.
Smart VSD (Variable Speed Drive) screw compressors apply high-efficiency inverters and dedicated motors to freely change the number of revolutions and supply the necessary compressed air in response to demand within the range of 100% to 15%, which greatly reduces energy consumption.
* The inverter compressor system controls the voltage and frequency of commercial power with a Variable Voltage Variable Frequency (VVF) to freely control the rotational speed of the MOTOR to maintain the standard pressure of the compressor.

Advantages of an inverter compressor

· Full-color 5.7” display (or Touch Screen)
· Networking up to 6 compressors
· Online visualization via ethernet connection
· Real-time trending on controller screen
· Day/Week Organizer
· Dual Pressure Band

· Graphic Service Plan Indicator · Efficient operation of the pneumatic system · Reduce the maintenance cost of pneumatic devices · Elastic change operation according to conditions · Cost and time savings for productivity improvement and facility maintenance

High efficiency inverter

High-efficiency inverters with durability equipped with easy-to-use control panels such as fast setup installation and rapid error diagnosis certified by UL, Cul, CE, and GOST-R, an internationally recognized testing agency in the Americas and Europe.

Inverter motor application

It is possible to prevent the dielectric breakdown of the private jet due to the inverter output frequency surge effect. In the case of a motor designed exclusively for inverters, even if used at low speed, it is cooled by a separate cooling fan attached to the motor shaft, so the temperature does not exceed the allowable value, so even when operating at a low speed, there is no risk of damage to the motor due to heat.

Smart touch controller exclusively for inverters.

Smart controllers exclusively for inverters with high performance and reliability not only control inverters to produce only the required amount of air by detecting fluctuations in air demand used in the field, but also control the shutdown of cooling fans according to discharge temperature.
