The Advantage of Hot and Cold Mist Treatment Today, aerosol treatment is one of the most modern and effective methods of carrying out preventative treatment and disinfection. You can find and purchase equipment for processing open spaces and premises of any complexity. But to carry out work guaranteeing quality and a long-lasting result, it is necessary not only to choose the generator of cold and hot fog correctly, but also need correctly composed technology that defines the conditions and processing order. Based on the characteristics of the treated object, aerosol treatment of premises is of the following types:
Cold fog is applicable for processing rooms in which plants or animals are located, for processing office or residential premises. In turn, hot fog is applicable for the treatment of greenhouses without high humidity and completely empty rooms. Cold fog treatment can be distinguished into a separate category using a mobile unit with an internal combustion engine, which is used to control pests and microorganisms on open ground (fields, kitchen gardens, gardens, etc.).
Hot mist treatment The very concept of “hot mist” does not mean at all that the spray mist is in a very hot state, it came from the method of forming aerosol drops. The working solution by injection moving at a high gas velocity is converted into aerosol. First, the liquid breaks into small drops, which subsequently instantly evaporate due to the large temperature difference between the environment and aerosol drops, spreading throughout the room. The performance of hot fog generators is an order of magnitude higher than similar models for working with cold fog, so processing with it is much faster. The fog emitted from the pipes has a temperature of about 60 degrees Celsius, and its drops do not exceed 20 microns in diameter. So small wet particles can soar in air for a relatively long time (up to 10 hours), having managed to penetrate into all secret corners of the room during this time. When processing rooms with hot fog, special care must be taken with precautions.
Cold fog treatment Unlike hot fog, cold fog leaves the spray unit at a temperature equal to the ambient temperature. When exiting, it disperses in the same way and fills the entire room, but since its drops are not heated and have a much larger diameter (from 50 to 100 microns), it is able to survive in the air for no more than 3-4 hours. It must be remembered that when using cold fog generators, water added to the reagent will spread throughout the room along with it, which can significantly increase humidity. This can both positively and negatively affect the environment. If an increase in humidity during the treatment with cold fog leads to undesirable consequences, before starting work, it is imperative to take measures to reduce the humidity in the room so that during the treatment the balance of the moisture ratio in the environment is restored.
