The cooling capacity of a standard 60-liter (60L) chest freezer can vary depending on the model and manufacturer. However, on average, a small chest freezer with a capacity of 60 liters typically removes around 400 to 600 British Thermal Units (BTUs) per hour.
Keep in mind that this is a rough estimate, and the actual BTU output may vary based on factors such as the energy efficiency rating, compressor capacity, and the ambient temperature of the surrounding environment. If you need precise information for a specific model, it's best to refer to the manufacturer's specifications or consult the product manual.
