AIRERA 75kW Screw Air Compressor: Frequently Asked Questions (FAQ)
Will the VSD compressor overheat when running at low frequencies (low air demand)?
We have optimized the cooling system for all operating conditions. The air-cooling system of the AIRERA 7.5kW VP series provides high-efficiency heat exchange, ensuring the air end and electrical components remain at ideal temperatures even at low motor speeds.
What is the starting method for this 75kW rated power model?
AIRERA uses Star-Delta starting by default to reduce starting current impact, but Variable Frequency Drive (VFD) is also available as an option. The VFD version automatically adjusts motor speed based on actual air demand, offering even greater energy savings.
What is the main maintenance challenge for the water-cooling system in the long run?
The key lies in water quality management. We recommend using softened water to prevent scaling in the cooler. AIRERA’s coolers feature an easy-to-disassemble design, allowing users to clean scale regularly and ensure heat exchange efficiency remains at its peak.
