General Description

This urn is an automatic, push button operated, volume brewing unit. It consists of a non- pressure vented water compartment of large capacity into which two stainless steel coffee liners are inserted. Also installed within this water compartment are electric immersion heaters thermostatically controlled through a contactor relay, to keep the water always at the desired temperature. Measurement of water quantity sprayed over coffee is by push button start, electric reset timer, timing a constant water flow rate to the spray nozzle.

Hot water from the water compartment is pumped to the spray nozzle, controlled by the reset timer. Automatic refill maintains water level in water compartment. Control system components are enclosed in stainless steel housings on both ends of the urn for the 87710 urn.

Air agitation of coffee mixes the brew with compressed air automatically at the end of the brew cycle or, if desired, manually at any time with a push button.
