Import Tips
• Verify motor power rating with manufacturer specs to confirm 186.5-746 kW classification; misstated power can lead to reclassification
• Include detailed technical datasheets showing semiconductor end-use to avoid general compressor duties
• Ensure CE marking or equivalent for safety compliance in high-pressure gas systems
