3 Fans External Rotor Motor Air Cooler | High-Efficiency Refrigeration Evaporator

Product description

The 3-Fans External Rotor Motor Air Cooler / Refrigeration Evaporator is specially designed for medium and large cold storage applications. Equipped with three high-efficiency external rotor motors, this unit delivers strong airflow and stable cooling performance while keeping noise levels low, making it ideal for environments where both performance and comfort are required.

Its heat exchanger uses copper tube with aluminum fins for optimal heat transfer efficiency. The housing is made of galvanized steel or stainless steel with anti-corrosion treatment, ensuring long service life even under low-temperature and humid conditions. Defrosting methods (electric, water, or hot gas) are available to meet different refrigeration system requirements.

Key Features:

Triple External Rotor Motors: Strong airflow, high efficiency, and low vibration.

Quiet & Energy-Saving: Optimized fan design for smooth and silent operation.

Efficient Heat Exchange: Copper tubes with expanded aluminum fins.
