The Server Signature Touch™ squeeze bottle warmer safeguards your toppings while keeping them ready for your final touch. Its 16 oz squeeze bottles are constructed of high-density plastic to withstand some heating; screw-off tops have a 1 1/4" opening for filling. Be aware, warmed product inside could make bottle too hot to handle comfortably. We suggest, ordering extra bottles (86809) for quick change outs or replacements; they are not as common as bottles for cold use. Bottles are dishwasher safe. The 120V warmer is thermostatically controlled to hold products at serving temperature in a water-bath. Topping warmer and squeeze bottle holder are constructed of stainless steel for durability and long life. Server warmers feature a thermostat that turns the heating element on or off as needed to eliminate burning or scorching.
