Abstract
An improved process for applying herbicides, insecticides and the like, as an aerosol or vapor using a thermal fogging apparatus. Particular methods can be performed through use of a programmable logic controller (PLC) that receives data and controls the main components of a thermal fogger system.
Claims8
A method for applying a chemical as an aerosol or vapor using a thermal fogging apparatus comprising:
- introducing a chemical in liquid or melted form;
- activating a pump to transport the chemical into a chemical preheater to raise the temperature of the chemical to a temperature below the evaporation temperature of the chemical;
- introducing the chemical into an output nozzle of the thermal fogging apparatus;
- setting a thermal fogger blower at a desired speed to introduce forced air into an air heater;
- introducing heated air from the air heater into the output nozzle to thermally fog the chemical.

A method for applying a chemical as an aerosol or vapor using a thermal fogging apparatus comprising:
- setting a starting variable frequency speed (VFD), setting a target nozzle temperature (NT), and setting a target pump velocity of the thermal fogging apparatus;
- operating the thermal fogging apparatus until a desired nozzle output temperature is achieved;
- activating and setting a pump speed on a chemical pump that is connected to a treatment chemical container;
- modifying the chemical pump speed to increase or decrease the speed of the chemical flow until the nozzle output temperature is consistently maintained;
- activating a chemical preheater at a predetermined temperature to raise the temperature of the chemical to a temperature below the evaporation temperature of the chemical;
- soaking the chemical to achieve a stable preheated chemical temperature;
- setting a nozzle output temperature at a predetermined temperature;
- setting a chemical pump speed at a predetermined speed;
- increasing or decreasing the preheater temperature setting if the nozzle output temperature is not maintained within a predetermined temperature;
