Delonghi DCU72 Ultimate Coffee Urn 20-60 Cup Capacity Keep Warm Function - Once it's finished brewing it automatically switches to the warming cycle and keeps your coffee at the perfect temperature. Freshness Indicator is activated by the keep warm function and tells you how long the coffee has been standing. Six indicator lights illuminate in increments of 1 hour each. Easy open cover with glass top lets you watch your coffee perking. And the special safety lock keeps the lid on tight to prevent spills. Cool Touch handles are heat resistent to allow you to move the urn from place to place without burning your fingers.
