Abstract: Improved systems and methods for the hydration of environments such as display cases, walk-in storage rooms, greenhouses and large-scale storage facilities are provided. Consistent humidification is provided while effectively eliminating the problem of water streaming from atomization nozzles at the end of a pressurization and atomization cycle. The present invention eliminates the traditional regulators, pressure tanks and solenoid valve assemblies required to control water pressure, as well as bladder tanks and regulator valves for regulating air pressure, while more effectively controlling the problem of streaming by incorporating a drawback valve and, optionally, a miniature water regulator. Kits for retrofitting existing humidification systems to incorporate the improvements described herein are also provided.
