Depending on the manufacturer, some metal drink dispensers feature a double-wall build that helps to retain heat and maintain temperature for a longer period of time. They are also insulated and designed to withstand a variety of conditions.
Some metal drink dispensers are ADA Compliant. These units have push buttons or extra-long dispensing handles that are easier for patrons and employees to operate. They also have a hygienic design that minimizes the risk of contamination. In addition to the above-mentioned features, a high-quality drink dispenser should have a safety shut-off feature, which cuts off power to the unit when no liquid is left in the reservoir.
