Oklahoma City, monthly values

Water-from-Air Resource Charts are now available for three cities in Oklahoma. Guymon is representative of Oklahoma's arid | steppe | cold arid climate zone. Tulsa and Oklahoma City are representative of the state's warm temperate | fully humid | hot summer climate zone. Water-from-air production from atmospheric water generators is fair to excellent during the late spring, summer, and early autumn months. Water production tends to be unreliable during the colder winter months when dew point temperature hovers around the freezing point of water. Please see the charts for details.

#Texas #Water from Air Resource

Austin, Texas monthly values

Water-from-Air Resource Charts are now available for nine locations in Texas: Amarillo, Austin, Corpus Christi, Dallas, El Paso, Houston, Pecos, San Angelo, and San Antonio. These locations are representative of the five Köppen-Geiger climate classes found in Texas. While details vary with location, a general finding is that atmospheric water generators will function well during summer months but may have unreliable water production during winter months.

Atmospheric #water generator technology entering maturity phase?

6/2/2013

Office Depot now has an water-cooler-sized atmospheric water generator (AWG) product available from its online store. This is a signal that water-from-air technology, especially that based on mechanical dehumidification, may be entering the maturity phase. Typically, technologies evolve through four phases: research & development, ascent, maturity, and decline.

The AWG product offered by Office Depot is the AquaBoy™ Pro from Atmospheric Water Solutions. Their technology embodies three US Patents (dated 1997, 2000, and 2001) by J. M. Zakryk.

#Colombia #Water from Air Resource

6/2/2013

Water-from-Air Resource Charts are now available for six cities in Colombia: Barranquilla, Bogotá, Cali, Cartagena, Medellín, and Villavicencio. Atmospheric water generators will function best with the excellent water-from-air resource in Barranquilla, Cartagena, and Villavicencio. The water-from-air resource is rated as good in Cali and Medellín but only as fair in Bogotá.

#Arizona #Water from Air Resource

1/2/2013

Water-from-Air Resource charts are now available for four cities in Arizona: Flagstaff, Phoenix, Tucson, and Yuma. August is the best month at all four sites for operation of atmospheric water generators. Machines using mechanical dehumidification cannot produce water at these four locations during November through May. The reason is the relatively low dew-points during these months. See the charts for details.

Hong Kong #Water from Air Resource

1/2/2013

Our Water-from-Air Resource chart for Hong Kong is now available. The resource varies with the seasons at this warm temperate | winter dry | hot summer climate site. Atmospheric water generators will produce water from the air at their rated capacities from April to September.
