Product Introduction

Product description and application

The 2×2 Fan Square Type Air Cooler, also known as a dual-row four-fan unit cooler, is an advanced refrigeration solution designed to meet the demands of medium to large-scale cold storage projects. Unlike traditional air coolers that usually arrange four fans in a single line, this model adopts a 2×2 square configuration, making it more compact, powerful, and efficient for specific industrial applications.

Application

Large cold storage warehouses: The 2×2 fan layout ensures strong air circulation, suitable for warehouses storing fruits, vegetables, meat, seafood, dairy products, and other perishables.

Blast freezer and quick-freezing rooms: Provides rapid and uniform cooling for frozen food processing, ensuring products reach target temperatures quickly and maintain freshness.

Food processing factories: Suitable for meat processing, seafood handling, and dairy production lines where even airflow is essential to maintain hygiene and consistent quality.

Logistics and distribution centers: Ensures stable temperature control during frequent loading and unloading operations, helping maintain product quality in the cold chain.

Pharmaceutical cold rooms: Provides reliable cooling performance for medicines, vaccines, and chemical products that require precise temperature management.

Features

Square 2×2 fan arrangement: Four fans are arranged in two rows, creating a compact square structure that delivers powerful and balanced airflow throughout the cold room.

Efficient heat exchange coil: High-quality copper tubes combined with aluminum fins maximize heat transfer efficiency, ensuring fast cooling and stable performance.

External rotor motors: Energy-efficient and low-noise fan motors provide strong airflow while keeping operating costs low.

Durable housing: The casing is made of powder-coated galvanized steel, offering corrosion resistance and long service life even in low-temperature and humid environments.

Defrosting options: Available with electric defrost, hot gas defrost, or water defrost systems to meet different refrigeration requirements.

Flexible refrigerant compatibility: Works with popular refrigerants such as R404A, R507, R134a, and R22.

Ceiling-mounted design: Saves floor space and ensures easy installation in different cold room layouts.

Advantages

Uniform airflow distribution: Compared with traditional single-row designs, the square 2×2 fan arrangement covers a wider area, preventing hot spots or uneven cooling.

Compact structure: Saves installation space, especially suitable for cold rooms with height restrictions or compact layouts.

Fast cooling performance: The combination of multiple fans and efficient coils ensures rapid temperature pull-down, improving operational efficiency.

Reliable and safe operation: Equipped with thermal protection devices and optional safety fan guards to ensure long-term stability and user safety.

Energy-saving design: High-efficiency fans and optimized coil structure reduce energy consumption while maintaining excellent performance.

Customizable models: Available in different capacities, fan diameters, and defrosting methods to meet diverse customer needs.

Factory-direct quality: Manufactured under strict quality control standards, offering stable supply and cost-effective pricing compared with smaller factories.

Conclusion

With its innovative 2×2 fan square design, the Square Type Air Cooler provides superior cooling efficiency, uniform airflow, and reliable performance for industrial cold storage and refrigeration projects. Whether you are building a blast freezer, a food distribution warehouse, or a pharmaceutical cold room, this air cooler offers the perfect combination of safety, durability, and energy efficiency.
