Cooling Capacity of Display Fridges – kW and BTU Explained in Plain Terms

Author: Echipa Modaco

Why Does the Cooling Capacity of a Display Fridge Matter?

When purchasing a display fridge for a shop, supermarket, or restaurant, one of the most important technical parameters is cooling capacity. Many business owners focus on dimensions, design, or the number of shelves, overlooking refrigeration output – and this can be a costly mistake. An undersized unit will fail to maintain the correct temperature, compromising product quality and increasing the risk of financial losses.

In the refrigeration industry, cooling capacity is expressed in two units of measurement: kW (kilowatts) and BTU (British Thermal Unit). Let's look at what each means and how to use them in practice.

What Is kW in the Context of Refrigeration Equipment?

The kilowatt (kW) is the International System unit used to express refrigeration output, i.e. the amount of heat extracted from a space or product per unit of time. The higher the kW value, the more efficiently the display fridge can cool and the greater the thermal loads it can handle.

For example, an open display fridge for dairy products installed in a high-traffic shop requires a higher cooling capacity than one situated in a low-consumption back-office setting. Ambient temperature, how often doors are opened, and the volume of stored products all directly influence the required refrigeration output.

What Is BTU and How Does It Relate to kW?

BTU (British Thermal Unit) is a traditional unit of measurement frequently used in American technical documentation and in the specifications of many compressors and refrigeration units. One BTU represents the amount of energy needed to raise the temperature of one pound of water by one degree Fahrenheit.

The conversion between the two units is straightforward and worth remembering:

  • 1 kW = 3,412 BTU/h
  • 1 BTU/h = 0.000293 kW

So, if a display fridge has a cooling capacity of 2 kW, this is equivalent to approximately 6,824 BTU/h. This conversion is essential when comparing technical specifications from different sources or when discussing requirements with an equipment supplier.

How Do You Choose the Right Capacity for Your Business?

Selecting the correct refrigeration output depends on several factors specific to your operation:

  • Type of refrigerated products – meat and fish require lower temperatures and more powerful units compared to beverages or bakery products.
  • Cabinet volume – the larger the interior space, the greater the refrigeration output required.
  • Ambient temperature – in restaurant kitchens or commercial spaces without air conditioning, display fridges work harder to compensate for the heat in the environment.
  • Access frequency – open display fridges or units with frequently used swing doors lose more cold air and require additional capacity.
  • Climate class – refrigeration equipment is classified into climate classes (SN, N, ST, T), which indicate the ambient temperature range for which the unit is designed.

A refrigeration equipment specialist can help you calculate the total thermal load and identify the display fridge with the optimum output, avoiding both oversizing (unnecessary costs) and undersizing (risk of breakdown and stock losses).

Modaco Display Fridges – Power and Efficiency for Your Business

With over 30 years of experience in manufacturing commercial refrigeration equipment, Modaco offers display fridges correctly designed and sized for the real needs of the Romanian market. Every unit manufactured at our factory in Găești, Dâmbovița County, is fitted with high-performance refrigeration units selected according to cabinet volume, operating temperature, and environmental conditions.

Whether you are the owner of a food store, supermarket, restaurant, or hotel, the Modaco range includes solutions with cooling capacities tailored to every application – from display fridges for pastry/confectionery to professional units for meat, cold cuts, dairy products, or beverages.

All our equipment comes with complete technical documentation, including refrigeration output values expressed in both kW and BTU, so you can make accurate comparisons and take informed decisions.

Conclusion

Understanding the units of measurement kW and BTU doesn't have to be complicated. Keep in mind that both express the same thing – the cooling output of a unit – and that choosing the correct value is essential for the efficiency and longevity of your display fridge. Don't improvise, and don't let yourself be guided solely by price or aesthetics.
