The Benefits of AUGUST VSD  DRIVE Rotary screw Compressor 15-35% direct energy saving.
S-T series CE and ASME approval / certification

It is just like getting a Rotary Screw Air  Compressor FREE of CHARGE. You can't belief it ??!!... just read this !!!

The Benefits of AUGUST S-T series  VSD DRIVE (VSD = Variable Speed Drive)  Rotary screw Compressor’s newest and latest technology in a rotary screw compressor for the compressed air industry.  This VSD rotary screw Compressor gives you a HUGE ENERGY SAVINGS on your electric bill.  The Brand has a decade of proven years of Premium Quality in our Rotary Screw air compressor, but now has added a Variable Speed Frequency Drive to its product range.  These compressors is equipped with  name brand ABB/ Danfoss / Telemacanique electrical components.  
In a work shop that runs a HIGH + LOW demand of air needs, the benefits of the Variable speed unit  are enormous !!!  The speed of the electric motor is controlled by the pressure the unit is producing under your real time air demand.  
All AUGUST S-T series  Screw Air Compressor come with PLC – Programmable Logistic Controller . As you can set your required pressure, the machine will only run to your air demands.  The lower the compressor RPM, the less air it pumps and the less amps the motor will pull. This allows you to buy a little larger machine to keep up with your business growth and air needs in the future, but only use the air and electricity that is needed and do not waste your money in a huge electric bill.    DON"T MISS IT

The whole idea of energy savings with this unit is the lower the cycles, the lower the amp draw coming from your electric motor.  The electricity amp draw that an electric motor is using determines what your electric bill is.  The lower the amp draw that your electric motor is using, the lower your electric bill will be!!  
The other and most definite savings on the Variable Speed Drive Machine is your motor bearings will have less wear with lower RPM and most of all, you will get an even longer rotary screw compressor life with lower RPM.  
The AUGUST S-T series  compressor does not need Y Delta Starting like our regular drive units.  So the Starting Benefits of this machine are even better than Y/Delta starting it starts from the Variable Speed Inverter Drive. This machine will start low cycles with only 33% of the full load amps and only low RPMs and will maintain the low amp starting for several seconds after the machines starts.  After the starting seconds under start up the unit will then start increasing the motor speed and CFM capacity.  This Variable Speed Drive unit also starts just like our regular drive unit because it is on a fixed second time delay, so there is no load on the unit under start-up mode.  Both no load start up combined with low cycle starting is another huge advantage you will gain on your electric savings.  
About : The PLC controller/computer gives you a wide range of advantages to control and operate your machine efficiently without worry.  The PLC gives you a maintenance parameter that you can easily view at any time during the compressor operation.  You can view your hours on the machine and also view the set list of hours that are put on the oil and filters for service and maintenance.  We set these machines up with a set amount of time you can put in the synthetic oil – oil/separator filter – air filter – and spin-on oil filter.  So when you go to the maintenance schedule you can view the hours on each maintenance item.  For example if your oil has 1530 hours on it and the maximum hours is set for 4000 for changing, you can view each maintenance item and know how much time there is before you need to change that maintenance item.   If you would lose track of changing these maintenance items, this machine has a built in alarm to warn you what needs to be changed listed on the computer screen.
•    The PLC also has a adjustable amp range and will protect your electric motor from too high of an amperage – this unit will shut down protecting the electric motor from any high amp draw.  This unit is also protected in case you might drop a phase. The PLC will sense this and shut down the compressor within 5 seconds after phase failure.
•    This PLC also has a list of amperage for each leg of the 3 phase which you can view as the unit is running.  This is nice to keep track on how your electric motor is performing as it is running.
•    This PLC will also keep track of over pressure--the unit will shut down on over pressure safety.
•    This PLC also has a adjustable range of time from 5 minutes to 20 minutes so when the unit is running under no load it will turn off and then automatically restart when the pressure gets to the low set point on the PSI.  This will save you energy so when the compressor is not being used you are not wasting electricity.
•    This PLC will also keep track of the total run hours.  It will keep track of the time the unit is pumping under load and the time under no load.  This makes it nice to keep track of your percentage of full load pump time.
•    The PLC will shut down the unit if it gets high in air temperature or if the unit runs low in oil.
•    The PLC will also sense if the unit is wired for the wrong rotation and it will not allow the unit to run.
•    The PLC is the connector for building a network of compressors, which will ensure that there is no down time during maintenance and save energy by switching to the right source of supply.
•    All function can be monitored remote by a standard PC with Windows OS.

ENERGY SAVING   VSD- Variable Frequency Screw Air Compressor
The Advantage of S-T Series Variable Frequency Screw Air Compressor
•    The start-up of VSD is even more smooth than so called “ Soft Start-Up” , the current of start-up is modified highly, and avoids the peak value entirely. It costs you less investment on electric power.
•    With the characteristic of super soft start-up, it avoids the peak value and starts up more smoothly. The pressure precision of the compressor could reach 0.01Mpa, the effect of energy saving is better and the performance is more steady.
•    The compressor could decrease the unloading through decreasing the ratio of rotating speed , decreasing the mechanical loss and its cost , increasing reliability of the compressor , prolonging the life time of the machine, and decreasing the operating noise .
•    PLC controller could display operating pressure , discharge temperature , set pressure . The display value could be set by inner parameter , the set pressure could be adjusted on the board.  Resulting in 15%～35% direct energy saving
•    The operation of low unloading of S-T series screw air compressor doesn't loss energy.
•    The energy loss because of switching between unloading and loading could be avoided.
•    S-T series screw air compressor could decrease the energy consumption because of more steady pressure and lower unloading pressure caused by precision pressure control.

So you are saving on the energy bill and maintenance costs as well as prolonging the parts’  life cycle.
Note: It is feasible, that within 3 years the VSD Drive Compressor will pay back the initial investment.
This is even more the case if you see the highly competitive pricing of AUGUST brand compressors.
