Optimized Airflow Design
These motors are paired with precision-engineered impellers (154mm/200mm) to deliver targeted airflow (25-378 m³/h), ensuring uniform cooling in freezers. The aerodynamic design minimizes turbulence and noise, enhancing efficiency while maintaining a quiet operation—critical for retail and storage environments.
Cold-Resistant & Durable Performance
Built to withstand extreme low temperatures (-30°C), the motors feature robust windings and bearings that prevent freezing and ensure long-term reliability. The IP20/IP42 protection rating safeguards against dust and moisture, making them suitable for harsh refrigeration conditions.
Versatile Compatibility
Available in 115V (YZF7-A) and 220-240V (YZF7-B) variants, these motors fit most commercial freezers, including display cases, walk-in freezers, and industrial cold storage. The compact design allows easy integration with existing systems, reducing installation time and costs.
