Types of a fan for cold storage

A fan for cold storage comes in various types, each designed to perform specific functions in a cold storage facility.

• Axial Fans

  An axial cold storage fan is a machinery that is commonly used in cold storage facilities. It is installed parallel to the airflow, hence, pushing the air in the same direction. The design of an axial fan allows it to cool the entire room quickly with a lesser volume of air. There are two major types of axial cold storage fans. The propeller fan has blades that are attached to the motor shaft and work the same way as an axial fan. The stationary part of the fan, known as shroud, surrounds the propeller and is cylindrical. Another type of axial fan for cold storage is tube axial. It contains a small cylindrical housing tube with an attached motor and fan blades.

• Blower Cold Storage Fans

  An cold storage blower fan works by pulling air from the cold room and pushing it back into the space. Its housing unit is bigger than that of an axial fan, and it rotates on a wheel housing called a squirrel cage. Cold storage blowers are efficient for warehouses that need high-speed air currents.

• Centrifugal Fans

  Centrifugal fans are designed to change the direction of air movement by using speed to push air pressure sideways. This forces the air perpendicularly into the cold storage room. Some features of centrifugal fans are the shroud surrounding them. They have a wheel that comprises an impeller that moves air. There are four major types of centrifugal fans: plug/fan on housing, direct drive fan, reverse polarization drive in-line duct, and belt drive fan.

• Mixed Flow Fans

  A mixed flow fan combines the axial and centrifugal fans. The design allows the impeller to mix the flow of air in the warehouse. The fan can be used for cold storage facilities that require flexible temperature regulation.

Specifications and maintenance of fan for cold storage

Specifications

• Fan sizes: Cold storage fans are available in different sizes to suit various cold storage facilities. The diameter of the fan blades typically ranges from small dimensions, such as 200 millimeters (approximately 7.87 inches), to larger sizes, such as 1,000 millimeters (approximately 39.37 inches).

• Airflow capacity: The airflow capacity of a cold storage fan is measured in cubic feet per minute (CFM). It indicates the volume of air the fan can circulate within a minute. A whiff with a higher CFM rating can move more air, resulting in faster cooling or ventilation. For cold storage applications, CFM can range from 500 CFM to 10,000 CFM or more, depending on the size and purpose of the fan.

• Fan speed: The fan speed is measured in revolutions per minute (RPM). Some cold storage facilities require a swift fan, while others do not. The common fan speed for a cold storage room is 1400-1800 RPM.

• Power consumption: Cold storage fans are designed to consume various amounts of electricity. Power consumption is usually measured in watts (W) or kilowatts (kW). The refrigerator's size, design, and function will determine how much power it needs to function. Typically, cold storage fan power consumption can range from 50 watts to several hundred watts.

Maintenance

• Clean the fan: Wipe the cold storage fan with a damp cloth or a small amount of detergent to keep it clean and minimize dust buildup. Regularly cleaning fans will help them work more efficiently and extend their lives.

• Check power cord and plug: Regularly check the power cord and plug of the cold storage fan to ensure they are not damaged and replace them promptly if they are.

• Lubricate the bearings: Cold storage fans typically have bearings that need to be regularly lubricated to ensure smooth operation. Adding lubricant to the bearings will keep them turning steadily.

• Temperature control: Users should pay attention to the operating temperature of cold storage fans. If the fan is overheated, users should promptly investigate and address the cause to prevent damage.

Scenarios of fan for cold storages

• Food industry cold storage fan

  Due to its ability to resist extreme temperatures and humidity, an axial fan is perfect for cold food storage warehouses. In these cold storage facilities, where items like produce, dairy, meat, and frozen goods must be kept at low temperatures to ensure their shelf life, axial fans are in charge of keeping the air flowing. Fans ensure consistent airflow, thus preventing the storage area from developing hot spots. This is crucial since uneven temperatures might cause food items to rot, expire, or go bad before their scheduled time.

• Pharmaceutical cold storage fan

  Certain medical and pharmaceutical items must be kept in cold storage facilities to preserve their stability. Refrigeration systems for pharmaceutical goods rely on cold storage fans to maintain a consistent temperature. If temperature changes occur, vaccines, medicines, and other delicate items may become less effective. To ensure that these items are preserved at the appropriate temperature, fans for cold storage must be utilized for airflow and temperature control.

• Cryogenic cold storage fan

  Fan cold storage is crucial for keeping perishable items, such as food and flowers, at subfreezing temperatures. A cold storage facility with a cryogenic system uses liquid nitrogen or carbon dioxide to produce extremely low temperatures. Cryogenic refrigeration is utilized in food processing to increase shelf life, suspend enzymatic activities, and retain freshness. Furthermore, cryogenic cold storage is employed in the food business to keep items like fruits and vegetables fresh for extended periods and to store large quantities of food goods close to the area where they will be processed or consumed to reduce waste.

• Blast freezer cold storage fan

  For rapid chilling and freezing things, a blast freezer cold storage fan is utilized. The airflow is boosted by a cold storage blast freezer fan, which lowers the temperature of the items more quickly. Furthermore, a cold storage blast freezer fan is essential because it boosts product output, protects food quality, and lowers the risk of freezer burn for cold storage in the frozen food sector. To preserve the food's flavor and texture, it's critical to have rapid freezing even at low temperatures.

How to choose fan for cold storages

Choosing the right cold storage fans requires careful consideration of several factors to ensure optimal performance, energy efficiency, and maintenance of the desired temperature. Here's a helpful buying guide to selecting cold storage fans:

• Storage requirements analysis

  Assess the size, capacity, and purpose of the cold storage facility (e.g., walk-in cold storage, refrigerated container, blast freezer). Determine the desired temperature range and the time the storage must maintain it. Analyze the storage's insulation and the impact of outside air on the facility.

• Fan type selection

  Choose the appropriate cold storage fan based on the function it is expected to perform. For example, if the goal is to cool down products quickly, a centrifugal cold storage fan is suitable for expelling air. On the other hand, an axial fan is more appropriate if the goal is to maintain product coolness by circulating air.

• Fan capacity calculation

  Calculate the required fan capacity (usually measured in cubic meters per hour, or CFM) based on factors such as the cold storage's volume, the desired air change rate, and the insulation of the storage facility. Utilize online tools or consult with experts to determine the recommended fan size for the specific cold storage setup.

• Energy efficiency consideration

  Choose a cold storage fan with a high-energy efficiency rating to minimize operational costs. Also, consider features such as variable-speed control, which allows the fan's speed to be adjusted according to the cold storage's needs, further enhancing energy efficiency.

• Noise level assessment

  Pay attention to the fan's noise level, especially if the cold storage facility is located near residential or commercial areas. Opt for a fan that produces low noise or consider sound insulation measures to reduce any potential disturbance.

• Durability and waterproof performance

  Choose a cold storage fan that is durable and, if necessary, has a strong moisture-proof performance to cope with the cold storage's humid environment and extend maintenance and use to avoid frequent replacement and repair costs.

• Installation and service

  Ensure the fan selected is easy to install, and opt for a manufacturer that provides prompt technical support and maintenance services. When the cold storage faces operation or technical issues, quick assistance can minimize downtime and disruptions to the business.
