Closed refrigerated display cases are Energy Star rated, and all units offer a number of options that can help increase energy efficiency.
Although closed refrigerated display cases are Energy Star rated, open units are not. Night curtains in open air models can be used after hours to hold in cold air and reduce energy usage at non-peak times or while operations are closed.
Highly efficient compressors, generously-sized condensers and evaporators and some evaporator motors can help increase energy efficiency.
LED and motion sensor lighting, along with insulated front glass and display sides, help conserve energy.
Because ambient temperature and humidity can affect a refrigerated display case's performance, these units should be used in temperatures under 90 degrees. Be aware that direct sunlight also can increase the run time of the units.
