Detailed Description Of SFe+ Series Inverter Air Compressor
- Air use
- Need more air when we work at day, on the contrary, using less
- 92% of the air compressors fluctuate seriously during operation
- The load of 70% of the air compressors is between 40-80%
- So there is great potential to use variable frequency compressor to save energy
- Permanent magnet frequency conversion motor with independent cooling fan to achieve 1 level energy efficiency requirements
- Frequency converter of double frequency conversion system, top vector variable frequency control system
- PID gas volume adjustment technology to meet the minimum energy consumption
- 6-13bar pressure is set arbitrarily to meet different pressure needs of customers
- 40-200Hz wideband amplitude modulation to meet customers’ different gas working conditions
- Adopt independent air intake system, the air volume is so large
- Constant pressure air supply, pressure fluctuating at ±0.1bar
- “0” load starts, the grid impact is small
- Low temperature zone high temperature zone layout is reasonable, electrical appliance life is longer
- There is human-machine interface, comprehensive data and powerful functions
