VSD Compressed Air Systems
Permanent Magnet Motor
Permanent magnet motor using high-performance NdFeB permanent magnet, 120 ℃ without losing the magnetic, life over 15 years.
Hollow coil with special frequency corona enameled wire, insulation performance, longer service life.
Can achieve soft start, run, the motor current will not exceed the full load current, at the same time, greatly reducing the impact on the grid equipment, electricity equipment will not cause damage.
Permanent Magnet Frequency Converter
Pneumatic stability: As the frequency of the screw air compressor using the inverter's stepless speed characteristics, through the controller or the inverter inside the PID regulator, can start gently; on the gas fluctuations in the larger occasions, but also fast Adjust the response.
Start without impact: As the inverter itself contains the soft start function, the starting current maximum rated current within 1.2 times, and the frequency of the general start in the rated current of more than 6 times compared to start the impact of small; Not only the power grid, the impact of the entire mechanical system, but also greatly reduced.
Perfect Monitoring System
Screw air compressor control system using intelligent microcomputer monitoring system, in order to meet the needs of the Chinese market, touch panel, stable and reliable, easy to operate, the operator without special training, only need to start and stop operation. Aurie series screw air compressor unit with automatic loading and unloading, automatic adjustment of the air intake, saving you energy. Unit with fault automatic diagnosis, display, alarm, protection and other functions. Can work in unattended 24 hours.

The Advantage of Variable Speed Air Compressor
Keep The Peace of Your Mind
Normal operation 67db, low operating noise to make it more suitable for the occasion
-
Self-displacement control
In the output of the displacement control function, the inverter in the constant power output, a pressure automatically corresponds to a maximum frequency, making the inverter running at a lower target pressure can provide more flat gas, and at higher target pressure Safe operation does not exceed power.
-
Industrial housekeeper function
Shanghai Rotorcomp compressor system, according to your factory work time pre-set the weekly work schedule, the compressor will be set in accordance with the set of work schedule, on-time automatic boot and shutdown, the real equipment to achieve 24 hours without On duty.
Save Your Money
To prevent the rapid changes in gas consumption time and space compressor system of frequent loading and unloading, to extend system life. The function of the pressure under the PID control more sensitive and controllable, even in the case of large changes in gas consumption, but also to prevent excessive unloading air compressor. Reduce the energy consumption due to changes in the larger problems caused by the compressor too late to reduce the speed and waste of energy
-
Eliminate useless power loss
The pressure sensor detects the pressure of the exhaust port and transmits the signal to the PLC. The PLC controls the output frequency of the inverter according to the pressure of the pressure sensor. When the pressure is large, reduce the frequency; when the pressure is small, increase the frequency so that the pressure is always constant. Compressor through the inverter to control the permanent magnet motor speed so that the composition of a frequency closed-loop control system to achieve constant pressure gas supply, multi-purpose production, less with less production, do not have to stop, useful soft start gas, completely put an end to the Energy loss of useless work.
Suitable for the system with large fluctuations in gas consumption, low load conditions
Frequency range from 25% -100%, the system with a large amount of gas fluctuations, energy-saving effect is more obvious

When buying air compressors, the traditional cost (ie, cost of purchase + maintenance costs), the proportion of only 25% of the total cost, while the energy consumption accounted for 75%. Ordinary (frequency) air compressor than ordinary (power frequency) air compressor energy saving 22-30%; Shanghai Rotorcomp variable frequency air compressor than ordinary (power frequency) air compressor energy saving 33-40%. (best screw air compressor for sale)
1. A 75KW ordinary air compressor, running 8000 hours a year, electricity 0.62 yuan / kWh, a year of electricity for the 75KW × 8000h × 0.62 yuan / (kw × h) = 372,000 yuan
2.Shanghai Rotorcomp VSD 75KW high energy-saving compressor, a year can save 35% of the electricity, a total of 372,000 yuan × 35% = 130,200 yuan;
3.The investment return period is about one year.
Running 8000 hours a year of rotorcomp energy efficient air compressor, power saving:
