Applications

MORE EFFICIENT WITH GERMAN TECHNOLOGY
  • Technology Innovation
  • Long Life
  • Low Noise
  • High Efficiency Air End
  • Low Vibration

  • The frequency conversion type supplies energy based on air demand, minimizing energy loss. With a low motor running frequency, mechanical noise is reduced.
  • Adjusting motor speed eliminates the need for repeated loading and unloading, lowering noise from these actions. Continuous loading pressure further reduces noise from unstable pressure.

Adopting frequency conversion speed control to make full use of energy-saving effect to create a new generation of energy saving compressor that saves electricity and energy

The conventional speed regulation method of the air compressor is to adjust the air intake volume by adjusting the inlet valve. The input power is large, and a large amount of energy is consumed in the current-carrying process of the valve. When using the variable frequency speed. If the flow requirement are reduced, the requirement can be the met by reducing the speed of the host.

Provide the necessary amount of air with the necessary pressure through constant pressure control

High-accuracy constant-pressure control with a pressure variation range of + 0.01 MPa or less can be performed, effectively providing the machine with the most suitable air pressure  necessary. Moreover, the accuracy of the set pressure is 0.01 MPa, accurate setting to achieve maximum energy savings.

  • In the newly developed HMI man-machine interface, it is very intuitive and convenient, which can directly realize the conversion of energy-saving mode and remote operation on the display screen. Moreover, in case of failure, the content of the failure will be displayed on the display , which can quickly troubleshoot the problem.
  • LOITHA unique closed-loop vector control and PID control not only realize fast response, but also ensure safety and reliability. The variable speed control of BPM series compressor and the system control of compressor and all technologies developed by LOITHA. The constant pressure control system accurate to 0.01Mpa not only achieves a high response, but also play a superior load tracking and safety.
  • The pressure control mode can be set and changed by touching the screen. Saving electricity pressure control mode can be easily changed on the display screen.
  • You can use the functions of timing operation, alternate operation, etc to save energy and save labor.
  • The status of the compressor and various settings can be confirmed on the display screen.

COMPARISON OF ENERGY-SAVING EFFECTS:

  • When buying an air compressor, the traditional cost ( ie, purchase cost + maintenance cost) accounts for only 25% of the total cost, while energy consumption accounts for 75%.
    • Standard VSD Screw Air Compressor Saves 10-20% Energy Than Fixed Speed Screw Air Compressor
    • Loitha PM VSD Screw Air Compressor Saves 33-35% Energy Than Fixed Speed Screw Air Compressor

 

FOR EXAMPLE

  1. A 50KW Standard screw air compressor runs for 6000 hours a year, with an electricity fee of Rs. 7/kWh, and the electricity charges for one year is: 50KW*6000 hours *7/KW.h= Rs. 21,00,000
  2. LOITHA 50KW PM VSD Screw sir compressor, saving about 35% of energy a year a Total of : 21,00,000*35%=Rs. 7,35,000
  3. Return of Investment (ROI) : About 1 Year
