Abstract

Apparatus for dispensing a heated gel includes a housing having a recess therein, a coupling assembly disposed in the housing and adapted to retain a pressurized gel container in the recess and a heater assembly disposed in the housing. The heater assembly includes a heater selectively operable to develop heat and a heat exchanger in heat transfer relationship with the heater and having a chamber for receiving a quantity of gel. The heater assembly further includes a first valve in fluid communication with a first portion of the chamber and operable to expose the chamber to pressurized gel and a second valve in fluid communication with a second portion of the chamber and operable to allow dispensing of gel without substantial foaming.
