Abstract
In an apparatus for the foaming-in-place of insulation, liquid resin and liquid foaming agent components are carried in first and second containers. These liquids are to be mixed together and the mix is to be foamed-in-place within a void to be insulated. Heating and cooling mechanisms are coupled to the conainers for selectively heating and cooling the liquids to maintain them within a prescribed temperature range. The heating and cooling mechanisms comprise part of a temperature control unit through which the liquids are selectively circulated from their respective containers. The temperatures of the liquids are monitored within the containers. In the event that the sensed temperature falls outside of the prescribed range, the temperature-control unit is automatically actuated to heat or cool the liquid.
