You can save energy and money by adding time clocks to vending machines. You also could run all the machines in your facility on a centrally-automated system. You could save $10-25 per year per machine.You can also reduce energy consumption by shutting off this kind of equipment when it is not needed. Many of these machines are grouped and can be controlled by a single time clock. Remember that you cannot install a timer on refrigerating equipment, since the contents may spoil. Free-standing drinking fountains often have a cord and plug beneath their shroud. Consider installing a plug-in timer to save energy.
