Hard Water and Humidification

Humidification is critical in many industries. Data centers, laboratories, and even commercial cigar humidors and wineries require precise levels of moisture in the air to operate within the specifications that ensure optimal performance. Water quality is a crucial consideration for any humidification system.

Water that is delivered from a municipality always has some type of contamination like  calcium, iron or magnesium. This can also be called hard water. These contaminants can hamper the humidification process. 

In a typical isothermal humidification application city water enters a sealed vessel called a steam canister. As the canister fills with city water, high voltage probes inside the canister arc between each other, heating the water to boiling and producing steam. Steam is delivered into the space or duct until the proper humidity set point is achieved.  During the boiling process heavy contaminants are left behind in the canister while steam is generated. This is why used canisters get heavy and gradually lose capacity, requiring expensive replacement year after year.

Ultra sonic humidification works differently. This process uses mechanical energy to generate water particles and evaporate water. This happens when a piezoelectric transducer placed below the water bed sends high frequency vibrations through the water bed to a point where mist is generated and is lifted by a fan. Any contaminants are simply atomized by the high frequency and carried out with the mist through the nozzel. Nothing is left behind, but this is where “white dust” comes from.

Providing clean water to a humidification system is imperative to prevent these undesirable outcomes. 

Ultra-Pure Reverse Osmosis and Deionization (RODI) systems use a five stage process to remove harmful substances, such as heavy metal ions and total dissolved solids from domestic water sources. This process converts city water to a stable 0-2 PPM perfect for humidification equipment. 

How hard is your water? See the graphic below (US_hardwater_Chart.png) to find out if you are in one of the six metro areas with the hardest water in the country. We can help you with your clean water needs no matter where you are or how hard your water is.
