Application Scenarios

- Textile mill air jet loom groups (air consumption varies with loom speed and fabric type).

- Intermittent glass production lines or pneumatic conveying systems.

- Low-pressure reaction processes with significant load fluctuations in chemical production.

- As an energy-saving, stabilizing airend for low-pressure air supply systems.

Customer Frequently Asked Questions (FAQ)

Q: What are the specific energy-saving effects of a low-pressure inverter compressor at low loads?

A: The effect is extremely significant. When air demand drops, traditional fixed-speed low-pressure compressors waste energy through blow-down or unloading. The SLV directly reduces output by lowering Drive Motor speed. At 50% load, it saves an additional 25%-40% energy compared to a fixed-speed unit; at 30% load, energy savings can reach 40%-60%.

Q: Does the inverter increase the risk of system failure?

A: KIMAIR uses industrial-grade, high-quality Inverter drives, with rigorous compatibility testing and derating design, ensuring extremely high reliability. The Control System has comprehensive protection functions like overcurrent, overvoltage, and overheating. Routine maintenance is similar to standard fixed-speed units, and the inverter itself is virtually maintenance-free.
