AIRERA 75kW Screw Air Compressor: Frequently Asked Questions (FAQ)
What are the advantages of Water-Cooling compared to air-cooling?
Water-cooling systems offer higher heat exchange efficiency and are unaffected by ambient temperature fluctuations. In high-temperature, dusty, or poorly ventilated environments, water cooling maintains a constant temperature more effectively, extending service life and ensuring stable air output 24/7.
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.
