What is an Electrostatic Sprayer for Disinfectants? An electrostatic sprayer is used to lay down disinfectant onto a surface by using electrostatic (electricity) charge. Different designs and operating principles of the products on the market vary in application and end-user requirements.
There are two basic types: cold sprayers and hot sprayers. There are also both direct-to-surface and indirect sprayers, and sprayers that can be used for either:
Indirect Hot sprayer: Usually use the process of condensation to produce fine particles (mist)
Direct Cold or a hot sprayer: No tank is needed in this type of unit. It uses compressed air or nitrogen gas to atomize the liquid inside a nozzle. In a direct cold sprayer, the pressure from compressed air or nitrogen gas is used to directly eject liquid from a nozzle, creating an aerosol that coats surfaces within reach of the nozzle.
For a hot sprayer, a high-pressure pump provides the energy to atomize and create a mist. This type of unit can be used for disinfecting areas where many people will contact the space after it’s been sanitized, such as a food service environment.
As well as cold and hot sprayers, there are “indirect” sprays that work indirectly via hydro or pneumatic atomization (see below). Another type is the manual sprayer, a pressurized hand spray bottle that allows for direct application of disinfectant to surfaces and objects.
How to Select an Electrostatic Sprayer for Disinfectant?
When you want to buy an Electrostatic Sprayer for Disinfectant, consider the following:
Materials to be disinfected and their volume – Some units can only handle a certain volume of liquid at a time.
Environmental conditions like temperature and humidity: If chemicals or disinfectants need to be heated or chilled before use, consider this, along with the capabilities of the unit.
Storage space: How much available storage space do you have for use with your disinfectant?
The frequency and concentration of chemicals used: Some units require the chemicals to be premixed before use, while others can handle concentrated chemicals applied directly onto surfaces through the machine.
Speed and pressure of atomization:
The speed and pressure at which the liquid is atomized, as well as droplet size, will affect how it coats surfaces.
Ease of use: Look for units that are easy to fill with chemicals and cleaners. Units that don’t require a power source or tanks can be more practical in some applications.
Type of disinfectant to be used: There are cold sprayers for use with one-step and two-step disinfectants and hot sprayers that can be used with chemicals at different temperatures.
