Abstract
A foam chemical dispenser apparatus having a chemical supply device and a dispenser device with housing and foam chemical output. A chemical passageway is provided from the source to the output. In a preferred embodiment, the passageway is at least partially defined by a hose and a chemical conduit formed in the dispenser housing. A heating system is included having a first heater element extending within the hose from a first end positioned closer to the chemical supply device to a second feedthrough supported end positioned closer to the dispenser device, and a second heating element is provided in the dispenser device. A temperature sensor system is included with a first temperature sensor positioned for sensing temperature of chemical in the hose and a second temperature sensor positioned for sensing chemical temperature in the dispenser device. A preferred embodiment has a control assembly communicating with the temperature sensor system and the heating system to maintain chemical traveling in the hose to the chemical outlet of the dispenser device at a chemical temperature above a predetermined minimum temperature (e.g., above 110 degrees F. despite the dispenser apparatus being in a cold environment). An embodiment of the invention also includes a slide facilitator at a free end of a coil heater element received within the hose.
