04:Advantages of VSD/VFC screw air compressor:
1. Cost Comparison Variable Frequency Control screw air compressor can prcecisely change the rotating speed of air compressor main motor according to change in gas consumption in the principle of stable discharge pressure,so that air compressor only output the required air compressor gas, while consuming only output energy of the compressed air necessary. So as to achieve energy savings and energy cost savings throughout the operation cycle in the unit will far exceed the price of air compressor itself.
2. Start and Run VSD/VFC machine is slowly accelerating started, more stable than the soft-start, completely avoid the current peak,start frequency operation after running to the rated pressure, and adpat to lack of electricity environment to the greatest extent.
3. Constant pressure air supply, with the balance of production The general air compressor and VFC air compressor operation comparison. VFC machine are free to regulate the rotating speed of the machine according to change in gas consumption,to achieve the balance of gas production and gas consumption, thus avoiding the machine frequent loading and unloading, making the frequency machine will save about 35 % of energy or more compared to traditional air compressor . Stable pressure output assures the pressure zone controlled within 0.01Mpa - 0.02Mpa, avoiding high load current consumption caused by the traditional compressor up to 0.05 - 0.2Mpa pressure zone.
05:Large-scale production department and high quality control on production
06:20 years manufacturing history and rich export experience,approved CE,ISO certificate
07:Full set of machine supply and service,including in air dryer,air filter,air receiver
