Refrigeration Sizing Estimate

U.S. Cooler® strives to provide our customers and dealers with tools to make the process of buying a walk-in as easy as possible.

PRO3-topmountTo find the BTU size of the refrigeration needed for your walk-in, we have provided a sizing tool to estimate the required BTU’s your unit will use.
There are many factors that are considered when sizing refrigeration for walk-ins such as ambient temperature (the temperature of the air surrounding the outside of the walk-in), temperature of product entering the walk-in, frequency of door opening and the holding temperature (the required constant temperature inside the cooler/freezer).

Enter your information below regarding your unit to receive an estimated BTU requirement.
