Design Features & Information
ENERGY SAVING FEATURES
Free Cooling
The StoreMaster packaged unit has been designed to provide the cooling load
required whilst optimising energy efficiency at all times and as such will take
advantage of free cooling whenever available. If the free cooling available
cannot satisfy the required full cooling load, DX (mechanical) cooling is used to
supplement the output.
