DrySmart’s patent application has been approved and published. The patent recognizes DrySmart’s use of modern technologies and methods in restorative heat drying. Perhaps even more important in today’s ligation prone society, restoration contractors can feel confident that the DrySmart heat drying system is not violating someone else’s patent. A portion of the patent description is below. For the complete patent, the link is below.
An embodiment of the present invention is directed to a drying system which provides an enhanced drying process through the use of modern sensors and control devices. Additionally, an autonomous portable exhaust blower removes moist air from the building and balances air flows and pressure. As seen in FIG. 1, the drying system 100 includes an indirectly fired mobile furnace 101 that can be trailered to the location of water-damaged building 103. Included with the furnace 101 is an air blower with motor 105 and an electric generator 107 for powering these and other devices. Propane tanks 109 provide fuel for the furnace and generator for up to 35 hours. This system is carried on a wheeled trailer 102 that may be towed behind a powered vehicle.
In operation, fresh air is input by blower 105 to the furnace 101 through a air intake filter box 111 where it is heated to a desired temperature and sent through hot air ducting 113 to a point interior to the building 103. The filter box 111 can be configured to use return air from building 103 to which the filter box 111 combines or adds “make up” air with air from the trailered furnace 101. A secondary function of the filter box 111 is to promote air circulation within the trailered furnace 101 and keep the trailer’s interior at a relatively cool temperature. Those skilled in the art will recognize the furnace 101 may utilize various sizes and different fuels. For example, a propane fueled 250,000 input British thermal unit (BTU) duct furnace is coupled with a 2,800 cubic feet per minute (CFM) backward inclined blower. Removing humid air from the building 103, autonomous exhaust blower 114 uses an exhaust hose 115 and may operate from within the trailer or from inside or outside the building 103. Incorporated with the autonomous exhaust system is a controller 116 and pressure differential transmitter 118 which modulates the volume of exhausted building air to maintain the building air pressure at the desired set point such that the air pressure may be positive, negative, or neutral. It should be recognized that the exhaust system is capable of running independently of the furnace trailer 101.
