Cold Temperature Potable Water Tank System and Device

Abstract

Embodiments of a cold temperature potable water tank system and device employ a water tank subsystem and a freeze prevention subsystem providing freeze protection for potable water within a water tank of the water tank subsystem. The water tank subsystem is positionable on and securable to a trailer subsystem and/or a skid subsystem, which enables the water tank subsystem to be used on the ground and carried on any load rated transport.

1 . A vessel, comprising:
 a water tank subsystem positionable on either a trailer chassis subsystem or a skid subsystem, wherein the water tank subsystem comprises a freeze prevention subsystem; and   a fastener subsystem for securely connecting the trailer chassis subsystem or the skid subsystem to the water tank subsystem.   
     
     
         2 . The vessel of  claim 1 , wherein the freeze prevention subsystem comprises a cold weather add-on kit comprising a freeze prevention control panel and a heating element. 
     
     
         3 . The vessel of  claim 2 , wherein the freeze prevention control panel is communicably coupled with the heating element. 
     
     
         4 . The vessel of  claim 1 , wherein the water tank subsystem comprises a tank and a sheet metal coating, and wherein the freeze prevention subsystem comprises thermal insulation between the tank and sheet metal coating. 
     
     
         5 . The vessel of  claim 4 , wherein the thermal insulation comprises sheets of self-adhesive, closed cell, ultra-low permeability foam. 
     
     
         6 . The vessel of  claim 4 , wherein the thermal insulation is mounted on hollow steel rails. 
     
     
         7 . The vessel of  claim 6 , wherein the steel rails comprise forklift pockets. 
     
     
         8 . The vessel of  claim 1 , wherein the water tank subsystem further comprises a sheet metal coating. 
     
     
         9 . The vessel of  claim 1 , wherein the fastener subsystem comprises a tank mount pad, a vessel mount and a frame mount pad. 
     
     
         10 . The vessel of  claim 9 , wherein the vessel mount comprises one or more thermoplastic elements. 
     
     
         11 . The vessel of  claim 10 , wherein the freeze prevention subsystem comprises insulation positioned in an insulation space and wherein the one or more thermoplastic elements extend into the insulation space. 
     
     
         12 . The vessel of  claim 1 , wherein the water tank subsystem comprises an internal lateral baffle comprising an opening, and wherein an internal heating element is positionable through the opening in the baffle. 
     
     
         13 . The vessel of  claim 12 , wherein the water tank subsystem comprises a tank and wherein the baffle is secured to an interior wall of the tank via a plurality of pipe elbows. 
     
     
         14 . The vessel of  claim 13 , wherein each of the plurality of pipe elbows are secured at a first end to the baffle and at a second end to the interior wall of the tank so as to provide a gap around a perimeter of the baffle. 
     
     
         15 . The vessel of  claim 1 , wherein the water tank subsystem comprises a top hatch and a vent. 
     
     
         16 . A freeze prevention subsystem for a potable water transport vessel, comprising:
 a cold weather add-on kit comprising a freeze prevention control panel and a heating element; and   thermal insulation.   
     
     
         17 . The freeze prevention subsystem of  claim 12 , wherein the thermal insulation comprises sheets of self-adhesive, closed cell, ultra-low permeability foam. 
     
     
         18 . The freeze prevention subsystem of  claim 12 , wherein the heating element is insertable into a potable water transport vessel for heating water in the potable water transport vessel.
