Reefer vans, 3-ph 480-v, avail power 3-ph 208

Not open for further replies.
Would like to install a couple of 40-ft reefer vans at a retail/warehouse location. All units we find are 480-volt 3-phase. Building has 208 3-phase. Any suggestions. Are transformers effecient? Considering just replacing the freezer units themselves with those that will run on 208 but rather expensive. the 480-volt appear to have become the standard of the industry. We also may want to install more units later on. Any ideas?
Thanks, Mark
