But, by paying close attention to water use and employing water conservation tools and methods, cooling tower operators can use water efficiently to facilitate essential energy and CO2 reductions, while limiting its total water needs and even earn credits\/rebates for lowering its usage.[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.22.2″ _module_preset=”default” max_width=”2160px” custom_padding=”0px||||false|false” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.23.1″ text_font_size=”16px” text_line_height=”1.8em” custom_margin=”0px||||false|false” custom_padding=”0px||||false|false” global_colors_info=”{}”]Over the last century, Marley\u00ae has been working to improve processes and technology to limit the use of natural resources<\/strong>.

_module_preset=”default” global_colors_info=”{}”]As detailed in Power Magazine<\/a>, \u201cthe purpose of a cooling tower is to conserve water. It fulfills its purpose by rejecting heat to the atmosphere by convective and evaporative heat transfer.\u201d The only water \u201clost\u201d is the pure water that is evaporated; the remaining cooled water is eventually blown down, or drained, and sent back into the water system.<\/p>\n The lower the heat load and\/or ambient temperature, the less evaporation. The higher the system\u2019s cycles of concentration (COC), the lower the blowdown. For more about limiting evaporation and\/or blowdown, see our white paper, \u201cHow to Conserve Water in Evaporative Cooling Towers<\/a>.\u201d<\/p>\n Water usage will vary greatly depending on the style of tower, the application and the conditions of the water entering the system.[\/et_pb_accordion_item][et_pb_accordion_item title=”Do water-cooled towers use more water than air-cooled towers? ” _builder_version=”4.27.0″ _module_preset=”default” global_colors_info=”{}” open=”off”]High-efficiency water-cooled towers, like the Marley NC\u00ae Everest\u00ae Cooling Tower<\/a>, use far less energy on-site than air-cooled solutions, but operators of water-cooled solutions may see higher water costs and usage at their location. However, as stated in ASHRAE Journal, \u201cthe hidden reality is that air-cooled or alternative systems consume more energy on-site [AND] use substantially more water at the power generation site\u2026\u201d<\/p>\n To learn more about this, download the ASHRAE article, \u201cA Review of Evaporative Cooling\u2019s Efficiency and Environmental Value.<\/a>\u201d This article shows how much water is used offsite when employing less-energy-efficient technology for your mechanical system.<\/p>\n Another water-saving option that’s becoming more popular for a variety of applications is an adiabatic cooling system. The Marley\u00ae OlympusV\u00ae Adiabatic Series<\/a> balances the water-saving benefits of an air-cooled heat rejection system with the energy efficiency of a water-cooled solution to provide flexible cooling for operators and engineers.[\/et_pb_accordion_item][et_pb_accordion_item title=”Can I conserve water in my existing mechanical system?” _builder_version=”4.27.0″ _module_preset=”default” global_colors_info=”{}” open=”off”]In most cases, yes! To start, operators should conduct all maintenance on their cooling tower as necessary and assure all its components are working properly and up-to-date technology is being employed. Water treatment or a water filtration system, like Marley WaterGard\u2122<\/a>, can also help raise cycles of concentration (COC) by limiting salts and minerals from entering the tower and reducing necessary blowdown.[\/et_pb_accordion_item][et_pb_accordion_item title=”How do I know how much water I am using or will use?” _builder_version=”4.27.0″ _module_preset=”default” global_colors_info=”{}” open=”off”]If you know the exact conditions of your specified\/installed cooling solution, you can enter them into our Water Calculator<\/a>. This tool can also help you identify how specific conditional alterations might help you limit water usage.<\/p>\n If you need help determining the conditions of your project or building, a nearby Marley representative<\/a> can help you gather the right information and find the best solution for your water conservation efforts.[\/et_pb_accordion_item][et_pb_accordion_item title=”Can changing my circulating flow rate reduce my water usage?” _builder_version=”4.27.0″ _module_preset=”default” global_colors_info=”{}” open=”off”]<\/p>\n In short, no. Evaporation rate closely follows heat load, regardless of whether water flow rate is high or low. The liquid-to-gas ratio, also known as L\/G (and defined as mass flow of water divided by mass flow of air) has a small impact on evaporation. If the amount of water is less than the amount of air (a low L\/G ratio), more evaporation can occur and vice versa. However, the product configuration and target thermal conditions dictate airflow required. If saving water is important, consult an SPX\/Marley representative to understand the options available.<\/a><\/p>\n [\/et_pb_accordion_item][et_pb_accordion_item title=”Does evaporation rate change based on location?” _builder_version=”4.27.0″ _module_preset=”default” global_colors_info=”{}” open=”off”]<\/p>\n Yes, evaporation rate is directly impacted by the ambient conditions. The atmosphere in warm, dry climates is very low relative humidity. This air naturally can accept more water vapor, which drives up evaporation rate. Conversely, a product with the same configuration installed in a more humid environment will exhibit a lower evaporation rate. The other primary factor is elevation. As barometric pressure decreases at higher altitudes, evaporation rate increases. For more information regarding your specific application please contact an SPX\/Marley representative.<\/a><\/p>\n [\/et_pb_accordion_item][et_pb_accordion_item title=”What is the typical water usage of an evaporative product?” _builder_version=”4.27.0″ _module_preset=”default” global_colors_info=”{}” open=”off”]<\/p>\n There are no universal rules that apply to every application and climate zone. The drivers are heat load, climate, and load profile throughout the year. It is not accurate to assume design day evaporation is constant year round. Evaporation rate decreases during cooler times of the year and when load decreases, which is common among HVAC systems. Evaporative products are energy efficient and environmentally friendly. Without the use of evaporation, less energy efficient modes of cooling would be used, which in turn drives more water usage at the power plant.
