7 ENERGY STAR for Rebuilt Refrigerated Vending Machines  Beverage companies rebuild vending machines to extend their life.  A vending machine can be rebuilt two or three times and stay in service over 15 years.  US EPA has a draft criteria for an ENERGY STAR rating for refurbished vending machines. Requirements  Refurbishment centre and original equipment manufacturer must be ENERGY STAR partners.  Rebuilt machine must meet the energy consumption and low- power mode requirements of ENERGY STAR.
