Overview


The Single Phase Low Speed EC Motor is a high-performance solution engineered for evaporative cooling systems, combining energy efficiency with reliable operation in high-humidity environments. Designed to drive cooling pads and misting systems, this motor delivers consistent airflow while minimizing power consumption, making it ideal for commercial greenhouses, livestock farms, and industrial cooling applications. Its low-speed design ensures quiet operation and extended lifespan, even in dusty or moist conditions.


Features


High Efficiency EC Technology: Utilizes electronically commutated (EC) technology for 30% energy savings compared to traditional AC motors, achieving IE5 efficiency ratings with constant torque output.

Humidity-Resistant Construction: IP54-rated enclosure and epoxy-coated windings protect against water splashes and dust, ensuring reliable performance in evaporative cooling environments.

Speed Control Flexibility: Integrated PWM controller allows 10-100% speed adjustment via digital signals, optimizing airflow based on ambient temperature and humidity levels.

Low Vibration Design: Balanced rotor and precision bearings reduce vibration (≤2.5 mm/s), minimizing wear on cooling system components and extending motor life to 50,000+ hours.

Easy Integration: Standard NEMA mounting dimensions and plug-and-play electrical connections simplify retrofitting into existing evaporative cooling setups.


Application


Ideal for environments requiring efficient thermal management, this motor excels in:

Greenhouse Cooling: Drives pad-and-fan systems to maintain optimal humidity and temperature for crop growth, reducing energy costs by up to 40%.

Livestock Facilities: Powers air circulation in poultry barns and dairy farms, preventing heat stress in animals while minimizing noise disturbance.

Industrial Cooling Towers: Provides reliable airflow for heat exchange in manufacturing plants, chemical facilities, and data centers with high-moisture environments.

Commercial Evaporative Coolers: Enhances performance in swamp coolers for warehouses, retail spaces, and outdoor event venues, ensuring consistent cooling efficiency.


Why Choose Us


Energy Leadership: Our EC motor technology complies with global energy standards (CE, UL, CSA), delivering lower operational costs and reduced carbon footprint.

Environmental Resilience: Tested to withstand 95% relative humidity and 50°C ambient temperatures, making it the most durable choice for harsh cooling environments.

Customization Options: Offer bespoke shaft lengths, voltage configurations (110V/220V), and thermal sensors for specialized evaporative cooling applications.

Service Excellence: 5-year warranty, 24/7 technical support, and a global network of service centers ensure minimal downtime and optimal system performance.
