The Cube was developed by AaquaTools to replace traditional hot high pressure washers that rely upon water heated through a coil that in turn makes the wash water non-potable and leaving particulates in the wash fluid. Because the Cube uses on-board tankless water heaters to generate hot water, the finished product is exactly the same as the source water, only heated. The Cube’s digital touch pad allows the operator to set a precise temperature, +/- only 1 or 2 degrees. The tankless water heaters are fired by clean burning, high quality propane or natural gas, providing more efficiency, increased reliability and makes it extremely user-friendly. No smelly diesel fumes or burner issues related to diesel, kerosene or less than high quality fuel.
