Abstract
A method for multi-agent dry fogging. The method includes pressurizing a first agent to a first range of pressure. The first agent includes a sterilant. The method also includes pressurizing a second agent to a second range of pressure. The second agent includes a non-depleting solution for protection against microorganism growth. The method also includes pressurizing a gas to a gas range of pressure. The method also includes atomizing the first agent at a nozzle to mix with the pressurized gas in a first application stage to disperse the first agent in a first dry fog within an ambient environment. The method also includes atomizing the second agent at the nozzle to mix with the pressurized gas in a second application stage to disperse the second agent in a second dry fog within the ambient environment.
