Why does my Water Production vary? Relative Humidity, Absolute Humidity and Dew Point.

We have customers that ask periodically why their water production declines in the Winter. While your humidity level (RH%) may stay in a similar range to what it was in previous months, the temperature will have an effect on the actual moisture in the air. You should also be looking at your dew point averages to get a better understanding in the fluctuation in the high and low moisture levels. The website weatherspark.com is a great starting point. Find the closest location to you, and view the Humidity and Dew Point charts.

Absolute Humidity is another major factor, as it is defined as the amount of water vapor present in a unit volume of air, usually expressed in grams per cubic meter. This would be a more accurate measurement of how much available moisture there is in the air, that your machine will be able to condense and collect.

EcoloBlue‘s machines are designed to still be able to produce some water in times of low moisture. However, when your regional location goes on the drier side, that is the beauty of EcoloBlue’s machines being hybrid units. Not only can they create water from the air when you are experiencing great humid air, you can also hook up your machine to municipal water during the drier times. While it is some people’s preference not to do that, you can be assured that EcoloBlue’s 12 stage filtration process, is removing all of the unwanted particles in your water.

Below are a couple links to explain all of this information further.

Absolute Humidity/Dew Point Chart: The table shows the “absolute humidity” in g/m3 (upper line) and the “dew point temperature” of the air in°C (lower line) for certain air temperatures as a function of “relative humidity. http://crescentok.com/staff/jaskew/isr/tigerchem/gas_laws/humiditykey.htm
