About the 67710E Coffee Urn

General Description

This coffee urn has been engineered to suit the special needs of the prison environment.
This section highlights the characteristics and special features of the product.

The urn is a large capacity, high-speed, coffee brewing and holding unit. The body is
constructed of two walls of stainless steel with insulation between. Inside is a large
capacity water tank where the brew is heated. Two ten gallon liners fit into that tank. Each
liner has its own controls which start and stop the brew process with the push of a button.
A pump draws water from the tank and sprays it over the grounds which are placed above
the liners. Faucets on the front of the urn allow the dispense of coffee from each liner and
hot water from the tank. A control automatically refills the tank as water is drawn off. A
thermostat regulates the temperature by switching electric heating elements inside the tank.
