Refrigeration Units for Walk-In Coolers

Refrigeration units are the heart of any walk-in cooler, ensuring that perishable goods are stored at precise temperatures to maintain their quality and safety. These units play a vital role in achieving consistent cooling, optimizing energy efficiency, and preventing costly spoilage. Whether you’re outfitting a small commercial setup or an industrial-grade storage facility, choosing the right refrigeration unit is key to maximizing your cooler’s performance.

Below, we’ll explore the differences between top-mount and side-mount systems, the top brands and models available, and how to select the best unit for your specific needs.

 

Top-Mount vs Side-Mount Units

When selecting a refrigeration unit, businesses often weigh the benefits of top-mount versus side-mount systems. Each type has distinct advantages depending on the cooler’s design, space constraints, and operational needs.

Top-Mount Units

Placed on top of the walk-in cooler, top-mount units are a popular option for businesses aiming to save space within the cooler itself. Here’s what you need to know:

Advantages 

  • Space Efficiency: Top-mount units don’t take up valuable storage space inside the cooler, leaving more room for products. 
  • Better Protection: Positioned above the cooler, these units are less exposed to dust, debris, and accidental damage. 
  • Improved Air Circulation: Top-mounted configurations allow cold air to flow downward naturally, achieving even cooling throughout the space. 

Drawbacks 

  • Ceiling Height Requirements: These units may not be suitable for locations with low ceilings. 
  • Maintenance Accessibility: Servicing the unit can be challenging as technicians may need ladders or lifts to reach it.

Side-Mount Units

Installed on the side wall of the walk-in cooler, side-mount units are an excellent choice for specific layouts or spaces with height restrictions.

Advantages 

  • Easier Access for Maintenance: Positioned at eye level, side-mount units are convenient for routine servicing and repairs. 
  • Versatile Placement: A good option when there isn’t sufficient vertical room to accommodate a top-mounted unit. 
  • Cost-Effective: Side-mounted units are often more affordable both in terms of purchase and maintenance costs. 

Drawbacks 

  • Reduced Storage Space: They occupy wall space within the cooler, potentially limiting shelving or storage capacity. 
  • Lower Cooling Uniformity: May require additional internal airflow controls to ensure even temperature distribution. 

 

Which Is Better? 

The choice between top-mount and side-mount units depends on factors like available space, how the cooler is used, and the ease of maintenance required for your business operations. Carefully evaluate your setup before making a decision.

Regardless of your cooler’s size or application, these brands bring top-notch performance and durability to your refrigeration setup.

Sizing Guide

Choosing the right refrigeration unit isn’t just about picking a reputable brand—it also comes down to selecting a model that matches your walk-in cooler’s dimensions and intended usage. An undersized unit may struggle to maintain temperatures, while an oversized unit could lead to unnecessary energy costs.

Calculating Cooler Volume

Begin by calculating the volume of your walk-in cooler in cubic feet:

Length x Width x Height = Volume in Cubic Feet

This measurement will serve as the foundation for determining the appropriate refrigeration capacity.

Key Considerations

1. Usage Frequency:

Coolers that are frequently accessed, such as those in busy kitchens or grocery stores, require units with higher cooling capacities to recover lost cold air.

2. Ambient Temperature:

Consider the external temperature of the location where the cooler operates. Units installed in hot or unregulated environments may need more power to maintain consistent temperatures.

3. Product Type:

Highly perishable items like raw meats or pharmaceuticals demand precise temperature control, often requiring units with advanced features for accuracy.

BTU (British Thermal Unit) Requirements

Refrigeration unit capacities are often measured in BTUs, indicating the amount of heat a unit can remove in one hour. Here’s a quick guide to calculating your approximate BTU requirement:

  • General Rule of Thumb: 56 BTUs per cubic foot of cooler space for walk-ins maintaining temperatures around 38°F.
  • Freezer Rule: 70 BTUs per cubic foot for freezers operating below 32°F.

For example, a 500-cubic-foot walk-in cooler used for general food storage would need approximately 28,000 BTUs (500 x 56) to keep items at the appropriate temperature.

Tip: Always consult with professionals to verify the BTU requirements based on your unique setup and cooling needs.

Ensuring Compatibility

When selecting a refrigeration unit, make sure it’s compatible with your walk-in cooler’s existing infrastructure, including:

  • Voltage and Electrical Configuration: Confirm that your facility’s electrical system can support the unit’s power requirements. 
  • Insulation Quality: Pair your refrigeration unit with high-quality insulation to prevent energy loss and ensure consistent performance. 
  • Ease of Integration: Modular coolers may allow for easier integration of units, while custom-built options might require specialized systems.
