Water Pre-Treatment
For All Humidity Control Systems Description - Operation - Features

The quality of water for all humidity control systems plays a primary role in the long term maintenance of equipment and overall system performance. This is especially true in the normal and qualitative function of high pressure nozzles.

In almost all cases, the two primary issues of concern for the appropriate water quality in each application is:

  1. Water Hardness - the potential to form scale buildup from the presence of calcium carbonate ions. For the control of water hardness, ACE recommends the use of locally sourced water softening or the ACE Scale X2 water treatment.
  2. Air Dusting - where air quality is critical, it is necessary to control air dusting, which is due to atomizing moisture directly into the air. The resulting dissolved solids form a fine white powder that consequently settles on all equipment and product. For best case water quality including the control of air dusting, ACE recommends our proprietary reverse osmosis system design OR the ACE Blending Valve used with outsourced DI Tanks.
  • Reverse Osmosis (RO) - A membrane filtration system producing the ideal water purity (98%) - RO water is in a state of equilibrium which is neither scale producing or corrosive. Reverse Osmosis is generally used in applications where humidity control systems require more than 2 gpm pump capacity as the longer term cost of gallons produced tend to favor using an RO System. Water quality can be "tuned" to match application and humidification equipment provided. Generally, we target a balanced water chemistry on the Langelier Saturation Index (LSI) which generally implies water that is neutral on the pH scale and have a TDS level of 10-40 ppm.
  • ACE Blending Valve Used with Outsourced DI Tanks - The Blending Valve was initiated as a low cost alternative to the traditional use of an Reverse Osmosis System. The Blending valve mixes the ultra pure water of the DI Tanks (Cation and Anion) with a pre- scribed amount of Raw Water to produce an output of 10-80 ppm total dissolved solids (TDS). This process transforms the water of the DI tanks from being too pure to an ideal water quality. The Blending Valve, once set to desired output, will automatically deliver the ideal water quality to the humidity control system. The Blending Valve approach to water treatment is generally considered to have a lower capital investment compared with RO systems for multiple reasons including: efficient use of all water (none is wasted), lower electricity costs, reduced corrosiveness of DI Water, and lower regeneration fees. Furthermore, the Blending Valve lengthens the life of the DI tank as well as the pump components.
  • ScaleX2 - A low cost alternative to water softening used primarily in a more normal range of water quality applications that do not for instance, have a higher than average iron content (see ScaleX2 pdf for details). The ScaleX2 filter converts dissolved hardness ions into solids which flow through harmlessly and therefore, the water loses its ability to form scale. A two year supply of 2 filters comes with each ScaleX2 unit. Generally, this technology has a more narrow range of application to be used on municipal water and not on well water supply whereas, traditional water softeners have a wider range of application.
