Fogging Systems

In a world increasingly dependent on humidification plant technology, VAI industries helps its customers dramatically reduce energy costs while meeting today’s more stringent indoor air quality (IAQ) requirements of fogging Systems.

The VAI Fog fogging systems uses high-pressure pumps to pressurize treated supply water to between 1000 and 2000 psi. The stainless steel orifice of Fog nozzles atomize the water into billions of ultra-fine fog droplets.

VAI Fog fogging systems do not require compressed air or heat. Direct pressure means there are few moving parts (none in the air handlers or the humidified space). The energy consumed is a small fraction of that required by other technologies, such as compressed air, ultra-sonic, or canister steam systems.

Every VAI Fog fogging systems is carefully and thoroughly engineered to fit the application. Our engineering staff will design the proper water treatment fogging systems and size the fog systems based on building heat loads, ambient climate data, ventilation rates, etc. Our fogging systems are widely used in Humidification plants, Greenhouse, Mushroom farms, Tea plant humidification, Dairy farms, sanitization booth/tunnel, and for many other applications.


The atmospheric conditions with respect to temperature and humidity play a very important part in the manufacturing process of textile yarns, fogging Systems, and fabrics. The properties like dimensions, weight, tensile strength, elastic recovery, electrical resistance, fogging systems, rigidity, etc. of all textile fiber whether natural or synthetic are influenced by Moisture Regain.

Moisture regain is the ratio of the moisture to the bone-dry weight of the material expressed as a percentage.

Many properties of textile materials vary considerably with moisture regain, which in turn is affected by the ambient Relative Humidity (RH) and Temperature. If a dry textile material is placed in a room with a particular set of ambient conditions, it absorbs moisture and in course of time,fogging Systems, attains equilibrium.

Some physical properties of textile materials which is affected by RH is given fogging Systems below:

  • Strength of COTTON goes up when R.H.% goes up
  • Strength of VISCOSE goes down when R.H.% goes up
  • Elongation %ge goes up with increased R.H.% for most textile fibers
  • The tendency for generation of static electricity due to friction decreases as RH goes up
  • At higher levels of RH , there is also a tendency of the fibers to stick together

Temperature alone does not have a great effect on the fibers. However the temperature dictates the amount of moisture the air will hold in suspension and , therefore, temperature, fogging systems and humidity must be considered together.

Greenhouse Fogging Systems


The fogging machine, or fogger as it is sometimes called, is a versatile piece of equipment that uses a fine spray to apply a chemical solution, often used for pest control, restricting the growth or mould or odour control. It is becoming increasingly popular as a means of sanitising surfaces.

One of the best methods growers use is a fogging system to regulate humidity and create an ideal setting for plants to grow. Fogging is essentially a visible cloud of water droplets suspended in the air, both cooling and moisturizing the grow environment.

The fogging system, or fogging system, is a system that shortens the environment in a short period of time and provides the moisture needed by the plants when used in the hill. It is also used to remove odors and odors, to create special effects by dust suppression, open air cooling and fog or smoke images.
