They are a two pass design that is both Water and Site Tight, minimizing splashout and reducing the potential for algae formation inside the tower.Water stays in …… sunlight stays out The EvapTech Fiberglass DesignThe EvapTech Fiberglass cooling tower product line is an advanced design which utilizes induced draft, counterflow technology–the most efficient in the industry and the best design for operation in a freezing climate. The counterflow design provides the EF cooling tower with inherently better operational and maintenance features as described throughout this brochure.4Principle of OperationWarm water from the heat source is pumped to the water distribution system at the top of the tower. Simultaneously, air is drawn in through the air inlet louvers at the base of the tower and travels upward through the wet deck fill opposite the water flow. A small portion of the water is evaporated which removes the heat from the remaining water. The warm moist air is drawn to the top of the cooling tower by the fan and discharged to the atmosphere. The cooled water drains to the basin at the bottom of the tower and is returned to the heat source to again collect system waste heat.The vertical air discharge of the EF design and the distance between the discharge air and fresh air intakes reduces the chance of air recirculation, since the warm humid air is directed up and away from the unit. This reduces the effective entering wet bulb and improves overall system efficiency.Optimum Design for Freezing Climates The counterflow fill design used in the EF Cooling Tower is well suited for winter operation. The wet deck surface is totally encased and protected from freezing winds thus inhibiting ice formation on the fill section. The even temperature gradient of the counterflow fill design makes the EF Cooling Tower the ideal unit for operation in freezing climates.The counterflow design of the EF Cooling Tower fill section reduces the chance of ice formation and with bottom support, eliminates fill collapse should ice form.Low Pressure Water Distribution SystemThe water distribution system in the EF Cooling Tower utilizes a single inlet header constructed of RTR or PVC for each fan cell to allow cell isolation. The headers feed PVC branch arms that supply ABS distribution nozzles. The entire distribution system is constructed of corrosion resistant materials to assure a long operating life with minimal maintenance requirements.WST Air Inlet Louver The WST air inlet louver screens on the EF Cooling Tower are constructed of corrosion-free PVC. They are a two pass design that is both Water and Site Tight, minimizing splashout and reducing the potential for algae formation inside the tower. In single pass or wide spaced louver systems used by other manufacturers, circulating water droplets tend to splash out, especially when the fans are shut off. With the two pass louver system, the water droplets are captured on the inward sloping pass and returned to the collection basin.This unique patent pending louver design completely encloses the basin area. Direct sunlight is blocked from the water inside the cooling tower, thereby reducing the potential of algae formation. Water treatment and maintenance costs are substantially reduced.While effectively containing the recirculating water and blocking sunlight, the louver design has a low pressure drop. The low pressure drop results in lower fan energy consumption, which further reduces the operating costs of the cooling tower. ™ Water Stays In ... Sunlight stays OutEF Series Fill OptionsThe EF Series cooling tower can be furnished with EVAPAK®, TechCleanTM, or VertiCleanTM PVC film fill. EvapTech fills are all designed to induce highly turbulent mixing of air and water for superior heat transfer but each offers specific application advantages. While EVAPAK® offers the largest heat transfer surface area, TechCleanTM and VertiCleanTM fills offer increasing levels of tolerance for circulating water contaminants with their vertically-offset flute and straight fluted designs. All EvapTech film fills are constructed of self-extinguishing, inert polyvinylchloride materials that will not rot or decay and are formulated to withstand water temperatures of 130 °F.EVAPAK®, TechCleanTM and VertiCleanTM fills all have excellent fire resistant qualities, with a flame spread rating of 5 per ASTM-E84-81a.Higher temperature fill is available for water temperatures exceeding 130 °F. Consult your EvapTech representative for further details.Drift Eliminators An extremely efficient drift eliminator system, EvapTech DriAirTM drift eliminators are standard on the EF Cooling Tower. The system removes entrained water droplets from the air stream to limit the drift rate to less than 0.002% of the recirculating water flow rate.With a low drift rate, the EF Cooling Tower saves valuable water and water treatment chemicals. The low drift rate also limits the exposure of the mechanical equipment to water and chemical carryover, extending its operating life and minimizing required maintenance.The drift eliminators are constructed of an inert polyvinyl chloride (PVC) plastic material which effectively eliminates corrosion of these vital components. They are assembled in sections to facilitate easy removal for inspection and maintenance of the water distribution system and the top of the fill area.Reliable Gear Drive SystemAll EvapTech EF Series Cooling Towers are provided with a standard right angle gear drive system. The gear drive system is carefully designed with a 2.0 minimum service factor and meets or exceeds all aspects of AGMA and CTI gear drive standards to assure long life and trouble-free operation. Also standard on the EF Cooling Tower is a 5-year maintenance free sealed gear design incorporating sealed casings, improved seals, synthetic oil and a low oil level switch to alarm in the chance that oil drops below an acceptable level. A 5-year warranty is also included with the EvapTech gear drive system.CouplingsThe EF Cooling Tower is provided with a standard polyurethane elastomeric couplings for close coupling applications (standard), composite and stainless steel components for drive shaft applications. Each of these choices are designed with a minimum safety factor of 2.0 per CTI standards. Appropriate drive shaft arrestors and coupling guards are supplied per OSHA requirements to protect equipment and operating personnel.Fan MotorsAll EF Cooling Tower models utilize heavy duty T.E.F.C. fan motors designed specifically for cooling tower applications. In addition to the standard motors offered on each cooling tower, EvapTech offers many optional motors to meet your specific needs, including: Premium Efficiency Motors Multi-Speed Motors Inverter-Duty Motors for VFD ApplicationsThe T.E.F.C. motors are mounted horizontally to allow proper drainage and to facilitate ease of removal. An available option relocates the motor outside the moist air stream with an extended full-floating driveshaft arrangement.FeaturesDRIFTELIMINATOR™5Stainless Steel Collection BasinThe standard arrangement for the EF Cooling Tower is to be installed on steel grillage by others. EvapTech will supply and install a Series 304 or 316 stainless steel collection basin including necessary basin accessories such as depressed side or bottom sump outlet(s), overflow and drain connection(s), and mechanical make-up valve(s). As an option, the tower can be installed on a concrete basin by others.The EvapTech stainless steel collection basin is a bolted construction utilizing a special gasket design to assure long operating life and leak-free operation. Unlike gaskets used by other manufacturers, the EvapTech gasket insures that it will remain sealed with an integral compression shim within the gasket that remains resilient in the most extreme environments. The design also incorporates closer bolting centers and joint overlay sealant. In order to demonstrate our confidence in this design, EvapTech backs the basin with a 5-year-warranty against water leaks.Bottom Inlet ConnectionThe EF Series Cooling Tower distribution system is arranged to provide a single bottom inlet connection per fan cell. The bottom inlet connection provides a beveled and grooved stainless steel connection for your choice of a welded or mechanically coupled piping arrangement. In addition to the obvious aesthetic advantages of eliminating riser piping, the bottom inlet arrangement provides the advantage of lower installed cost since riser piping supports are eliminated and supply piping can often be supported from the same steel structure that supports the cooling tower. For those installations requiring bypass connection for winter operation, this arrangement also reduces the cost of bypass piping due to its proximity to the collection basin. As an option, a side inlet piping arrangement with flanged connections can be supplied.Casing Appearance OptionsThe EF Cooling Tower offers standard improved aesthetics with its clean cased lines and bottom inlet piping design. The appearance can be further improved by incorporating architectural consideration into its design.A standard option to extend the casing from the fan deck to the top of the perimeter handrails is available. This option eliminates the view of the extended tower column, handrail, knee rail, and toe board and replaces it with a clean continuation of the casing. This option also hides any exposed mechanical equipment and anything placed on the fan deck to facilitate maintenance.Another popular option includes upgrading the casing to architectural pultruded fiberglass panels. In addition, both casing options are available in custom colors to better integrate into the surrounding architecture.Electric Heaters & Water Level Control Options Electric immersion heaters are available as an option and are located in the basin of the tower. They are typically sized to maintain a 40 °F pan water temperature at 0 °F ambient with fans off. They can be furnished with a combination thermostat/low water protection device to cycle the heater and to prevent their operation absent water in the basin.EvapTech cooling towers are available with an optional electric water level control system in place of the standard (with SS basin) mechanical make-up valve and float assembly. This package provides very accurate and reliable control of the collection basin level. The system consists of stainless steel electrodes, electric relay, and slow close solenoid valve.Low Sound OptionsVarious options are available to mitigate the sound generation from the EvapTech EF Cooling Tower including low speed fans, low noise fans, and falling water silencers. Ask your EvapTech representative to review your needs and present available options.Features & Options™Photos courtesy of Howden Cooling Fans6Model No. Motor Number of Cells H.P. 1 2 3 4Model No. Motor Number of Cells H.P. 1 2 3 4Model No. Motor Number of Cells H.P. 1 2 3 4Model No. Motor Number of Cells H.P. 1 2 3 4TOWER CAPABILITY IN USGPM AT THE FOLLOWING TEMPERATURE CONDITIONS (°F) 90° EWT 80° LWT 68° WB 90° EWT 80° LWT 72° WBEF Series Field Erected Cooling TowerThermal Performance EF#18-424E 30 3,214 6,429 9,643 12,729 EF#18-424E 30 2,557 5,114 7,671 10,126 EF#18-424G 40 3,506 7,012 10,518 13,883 EF#18-424G 40 2,789 5,578 8,367 11,044 EF#18-424H 50 3,742 7,483 11,225 14,817 EF#18-424H 50 2,976 5,953 8,929 11,787 EF#24-424E 30 3,834 7,668 11,502 15,183 EF#24-424E 30 3,050 6,100 9,150 12,078 EF#24-424G 40 4,222 8,443 12,665 16,717 EF#24-424G 40 3,358 6,716 10,074 13,298 EF#24-424H 50 4,545 9,090 13,635 17,998 EF#24-424H 50 3,615 7,231 10,846 14,317 EF#24-430H 50 5,280 10,559 15,839 20,907 EF#24-430H 50 4,200 8,400 12,599 16,631 EF#24-430J 60 5,633 11,265 16,898 22,305 EF#24-430J 60 4,481 8,961 13,442 17,743 EF#24-430K 75 6,043 12,085 18,128 23,929 EF#24-430K 75 4,807 9,614 14,420 19,035 EF#30-430H 50 6,197 12,393 18,590 24,539 EF#30-430H 50 4,929 9,859 14,788 19,520 EF#30-430J 60 6,586 13,173 19,759 26,083 EF#30-430J 60 5,239 10,479 15,718 20,748 EF#30-430K 75 7,091 14,182 21,274 28,081 EF#30-430K 75 5,641 11,282 16,923 22,338 EF#30-436J 60 7,629 15,258 22,887 30,211 EF#30-436J 60 6,069 12,138 18,206 24,032 EF#30-436K 75 8,214 16,429 24,643 32,529 EF#30-436K 75 6,534 13,069 19,603 25,876 EF#30-436M 100 9,038 18,076 27,114 35,790 EF#30-436M 100 7,189 14,379 21,568 28,470 EF#18-424E 30 2,886 5,772 8,659 11,429 EF#18-424E 30 2,584 5,168 7,751 10,232 EF#18-424G 40 3,148 6,296 9,444 12,466 EF#18-424G 40 2,818 5,636 8,454 11,160 EF#18-424H 50 3,360 6,719 10,079 13,304 EF#18-424H 50 3,008 6,015 9,023 11,910 EF#24-424E 30 3,443 6,885 10,328 13,633 EF#24-424E 30 3,082 6,164 9,246 12,204 EF#24-424G 40 3,790 7,581 11,371 15,010 EF#24-424G 40 3,393 6,787 10,180 13,438 EF#24-424H 50 4,081 8,162 12,243 16,160 EF#24-424H 50 3,653 7,307 10,960 14,467 EF#24-430H 50 4,740 9,481 14,221 18,772 EF#24-430H 50 4,244 8,488 12,731 16,805 EF#24-430J 60 5,057 10,115 15,172 20,027 EF#24-430J 60 4,528 9,055 13,583 17,929 EF#24-430K 75 5,426 10,851 16,277 21,485 EF#24-430K 75 4,857 9,714 14,571 19,234 EF#30-430H 50 5,564 11,128 16,691 22,033 EF#30-430H 50 4,981 9,962 14,943 19,725 EF#30-430J 60 5,914 11,828 17,741 23,419 EF#30-430J 60 5,294 10,589 15,883 20,965 EF#30-430K 75 6,367 12,734 19,101 25,213 EF#30-430K 75 5,700 11,400 17,100 22,572 EF#30-436J 60 6,850 13,700 20,550 27,126 EF#30-436J 60 6,132 12,265 18,397 24,284 EF#30-436K 75 7,376 14,751 22,127 29,207 EF#30-436K 75 6,603 13,206 19,809 26,147 EF#30-436M 100 8,115 16,230 24,345 32,135 EF#30-436M 100 7,265 14,530 21,794 28,768To Make a Selection: Locate the table with the desired operating temperature conditions. Locate the GPM values that are equal to or greater than the required flow rate. Read vertically from the selected GPM value to determine the number of cells. Depending on the required water flow rate, there may be more than one model that can be selected. Generally, the selection with the least number of cells will have the lowest installed cost. Once the number of cells is determined, read from the GPM value horizontally to the left to find the model number and replace the # symbol with the preferred number of cells to complete the model number of the unit. Note: The data in these tables are for single and multiple cell towers with an open air inlet on all four faces. Alternate applications may be selected in multiple tower configurations if adequate clearance is provided between towers.

Once the number of cells is determined, read from the GPM value horizontally to the left to find the model number and replace the # symbol with the preferred number of cells to complete the model number of the unit. Note: The data in these tables are for single and multiple cell towers with an open air inlet on all four faces.
