Choose the optimum humidification method

The humidification method to prevent static electricity from happening

Last week we explained the difference between relative and absolute humidity, and the importance of considering the temperature and the relative humidity as countermeasure for static electricity. Humidity is a key element to prevent static electricity.

Let’s compare humidification methods.

Features of three humidification methods

Because there are many humidifiers in the world, many people say “I do not know exactly which one to choose”.

Therefore, here we will introduce the optimum humidification method for production sites:

the “Dry fog humidification”

First of all, let’s compare the three different humidification methods:

  1. Steam humidification: evaporation with steam water above 100℃
  2. Vaporization type of humidification: evaporation by blowing water with air
  3. Water spray humidification: evaporation with water mist

Either method eventually evaporates the water and changes it to humidity, but the important aspect in selecting the humidifier is to know the characteristics of each humidification method.

Choose the one that best suits your humidification purpose and your production site (Table 1 upper 3 rows).

Table 1. Characteristics by humidification method

Steam humidification use to be the conventional humidification system on production site in order to easily control and stabilize humidity level. However, as heat generated from production machines is getting bigger, the number of sites that need to be cooled down all year long increased. Since steam humidification itself is also a source of heat, it became necessary to generate extra cooling.

Therefore, switching to a water spray humidification, with a cooling effect at the same time as humidification, got quickly accepted.

The “Dry fog” trend spreading worldwide

The biggest disadvantage of water spray humidification was “mist wetting things” and “nozzle clogging”.

The water spray humidification method which overcomes these two disadvantages is the “Dry Fog humidification” (last row of Table 1).

Our solution for “Dry Fog humidification” is the humidifier AKIMist®” E “.

The humidifier AKIMist® “E” generates a fine dry fog, which replicates the natural hazy mist you can experience in the nature. The mist is so fine that it does not wet the environment and the surrounding objects. Thus, it does not clog the nozzle.

It is a total humidification system which can control the precise humidity level wanted with the installation of a sensor to the control panel.

This humidification method is the optimum solution with:

  • Its double advantage of humidifying while cooling;
  • Its specific feature of humidifying with water WITHOUT WETTING;
  • All while “providing an environment that does not generate static electricity” at the production site;
  • As well as being an “energy saving air conditioning humidification system”, considering today’s economy and the importance of cost savings.

It has various applications and high results in different industries and processes (Table 2).
