5 F U T U R E, A V A I L A B L E T O D A Y! DESIGN AND CONSTRUCTION FEATURES EVAPCO is proud to introduce the latest in evaporative condenser technology, the PMCQ. This Evaporative Condenser features Quiet Super Low Sound Technology and is Easy to install... Easy to maintain... and Energy Saving! Water Saver Drift Eliminators New patented design reduces drift rate to 0.001% Saves water and reduces water treatment cost Greater structural integrity vs. old style blade-type Recessed into casing for greater protection Drift rate certifications as per Eurovent OM Double-Breake Flange Joints Stronger than single-brake designs by others Minimizes water leaks at field joints Greater structural integrity Unique Field Seam Eliminates up to 85% of fasteners Self guiding channels improve quality of field seam to eliminate leaks Easy to install Lower installation cost Individual Fan Drive System Increased flexibility for improved capacity control Greater reliability through redundancy Easy motor replacement Front mounted drives for improved maintenance accessibility Sloped Pan Bottom Pan bottom slopes to drain Easy to clean Stainless steel strainer resists corrosion 5 DESIGN

6 D E S I G N F E A T U R E S Principle of Operation The refrigerant gas is discharged from the compressor into the inlet connection of the evaporative condenser. Water from the condenser s sump is continuously flooded over the condenser coil, while ambient air is simultaneously forced into the unit. As the ambient air moves up through the coil section, a portion of the spray water is evaporated into the air stream. The evaporative process cools the spray water, which in turn cools the tubes containing the refrigerant gas. The cool tube walls cause the refrigerant gas to give up heat and condense into a liquid. The condensed liquid flows out of the coil s sloping tubes to the high pressure liquid receiver for return to the system. The hot, saturated air is driven through the drift eliminators, where any entrained water droplets are removed. The condenser s fan then Proven Performance & Design Flexibility The new PMCE/PMCQ Evaporative Condenser offers more capacity and greater system design flexibility than ever before. EVAPCO's research and development team has invested hundreds of hours in laboratory testing to develop the next generation in Forced Draft Condenser Technology. These efforts have produced a totally new fan section design which is now combined with the proven Thermal-Pak II coil technology to offer improved condenser performance. The PMCE/PMCQ features more plan area options and fan horsepower options for the system design engineer. With more condenser capacity, more plan area options and greater flexibility in motor selection, the design engineer can now match the condenser performance to the specific application requirements. More equipment choices and more design flexibility mean greater value for the End-User. Patented Thermal-Pak II Coil Design Superheated Refrigerant Gas In Condensed Refrigerant Liquid Out Cool Dry Entering Air Hot Saturated Discharge Air Principle of Operation (PMCQ shown) discharges this air stream out of the top of the unit at a high velocity, where it can dissipate harmlessly into the atmosphere. The water which was not evaporated falls into the sump and is recirculated by the spray pump to the water distribution system above the condensing coil section. Lower Refrigerant Charge Only EVAPCO condensers offer the patented* Thermal-Pak II Coil which assures greater operating efficiency in your condenser. Its unique elliptical tube design allows for closer tube spacing resulting in more surface area per plan area than traditional round tube designs. Thermal-Pak II Coil by EVAPCO The Thermal-Pak II Coil design has lower resistance to air flow and permits greater water loading, making the Thermal-Pak II Coil the most efficient design available. And now with its new tube circuiting and orientation pattern, the Thermal-Pak II coil yields a lower refrigerant charge. The coils are manufactured from high quality internally enhanced CROSSCOOL carbon steel tubing following the most stringent quality control procedures. Round Tube Coil by Others Each circuit is inspected to assure the material quality and then tested before being assembled into a coil. Finally,the assembled coil is tested in accordance with the Pressure Equipment Directive (PED) 97/23/EC. To protect the coil against corrosion, it is placed in a heavy-duty steel frame and the entire assembly is dipped in molten zinc (hot dip galvanized) at a temperature of approximately 430 C. *U.S. Patent No DESIGN 6 Superior Water Saver Drift Eliminators The PMCE/PMCQ condensers incorporate a patented* highly efficient PVC drift eliminator. The eliminator removes entrained water droplets from the air stream to limit the drift rate to less than 0.001% of the recirculating water rate. The efficient of the eliminators is certified by Eurovent and tested in accordance with OM Please consult for additional informations. With a low drift rate, PMCE/PMCQ condensers save valuable water and water treatment chemicals. The eliminators feature a honeycomb design which offers greater structural integrity and are recessed in the top of the casing and UV protected for longer life. They are constructed of inert polyvinyl chloride (PVC) which eliminates corrosion in this critical area of the condenser. The eliminators are assembled in sections for easy handling and removal for coil and water distribution system inspection. *U.S. Patent No

7 D E S I G N F E A T U R E S Energy Efficient for Lowest Operating Cost Lower Horsepower Options The new fan drive system of the PMCE/PMCQ utilizes large diameter fans in a vane-fan arrangement to provide more efficient air flow and reduced power consumption. When compared to the traditional centrifugal fan condenser models, the vane-axial fan design can offer up to a 50% reduction in energy consumption. And, with the new PMCE/PMCQ model selections even more low horsepower options are available to obtain greater energy savings. Individual Fan Drive System Capacity Control Flexibility & Operating Redundancy The new PMCE/PMCQ fan drive system provides individual motor to fan configuration as standard equipment on all models. The dedicated fan to motor arrangement ensures less wear & tear on the drive system versus tandem fan motor drive arrangements resulting in less maintenance. The individual motor to fan design offers greater capacity control flexibility to match the system load requirements. In addition, all Evapco condensers are equipped with an internal baffle system which extends from the pan bottom vertically through the coil bundle. This unique design allows the user to cycle fan motors independently without harmful effects of air by-pass inside the unit. The individual motor to fan design ensures maximum operating redundancy in the condenser fan system when critical operation is necessary. EVAPCOAT Corrosion Protection System (PMCQ shown) The Z-725 Mill Hot-Dip Galvanized Steel Construction is the heaviest level of galvanizing available for manufacturing evaporative condensers and has more zinc protection than competitive designs using Z-275 and Z-600 steel. Z-725 ZINC STEEL ZINC EVAPCO There are various grades of mill galvanized steel each with differing amounts of zinc protection. EVAPCO has been a leader in the industry in developing heavier galvanizing, and was the first to standardize on Z-725 mill hot-dip galvanized steel. Z-725 designation means there is a minimum of 725 g/m 2 total zinc present on the steel. During fabrication, all panel edges are coated with a 95% pure zinc-rich compound for extended corrosion resistance. Z-600 Z-275 OTHERS 85% Fewer Fasteners Lower Installed Cost The PMCE/PMCQ features a new field seam design which ensures easier assembly and fewer field seam leaks. The field seam incorporates new selfguiding channels to guide the coil casing section into position and set in place on the bottom fan section of the condenser. In addition, the new design eliminates up to 85% of the fasteners typically used to join the condenser sections in the field significantly reducing the contractor labor costs for installation. 7 DESIGN

8 M A I N T E N A N C E A D VA N TA G E S Improved Maintenance Oversized Access Door For enhanced basin accessibility, the Oversized Access Doors (standard for PMCQ - optional for PMCE) enable maintenance personnel to quickly and easily enter the basin for float valve adjustment and unit inspection, cleaning and maintenance. Fan Drive Accessibility The drive components of the PMCE/PMCQ are easily accessed for routine maintenance from the front of the unit. Bearing grease fittings are extended to the outside of the unit for ease of lubrication. All drive sheaves have been relocated to the front of the fan section and motors are positioned on a platform base to allow for easy belt tension adjustment. Easy Clean Sloped Basin The PMCE/PMCQ drain pan is designed to improve maintenance access and make it easier for operating technicians to clean. The bottom of the pan is sloped to the unit drain to ensure that the basin will completely drain and allow sediment and debris that may collect in the basin to be easily flushed from the unit. The design helps to prevent buildup of sedimentary deposits, biological films and standing water. Pressurized Water Distribution System The water distribution system is made of schedule 40 PVC pipe and ABS plastic water diffusers for corrosion protection in this key area. The piping is easily removable for cleaning. The water diffusers have a large orifice and are practically impossible to clog. They also have an anti-sludge ring extending into the headers to prevent sediment from building up in the diffuser opening. All PMCE/PMCQ units have as per standard the ZM II Nozzle to ensure that every square meter of heat transfer surface receives complete and even water coverage, resulting in maximum thermal performance. ZM II Nozzle Clean Pan Basin Design The basin of the New PMCE/PMCQ is sloped toward a depressed area where the drain is located. With the "Clean Pan" design, it is easy for a service mechanic to flush the pan. MAINTENANCE Stainless Steel Strainers The EVAPCO standard for many years, the stainless steel strainer is one component that is subject to excessive wear and corrosion. With stainless steel construction, this component will last the life of the unit. 8

9 O P T I O N A L E Q U I P M E N T Two Speed Motors Two speed fan motors can provide an excellent means of capacity control. In periods of lightened loads or reduced wet bulb temperatures, the fans can operate at low speed, which will provide about 60% of full speed capacity, yet consume only about 15% of the power compared with high speed. In addition to the energy savings, the sound levels of the units will be greatly reduced at low speed. Remote Sump Configuration For units operating in areas where temperatures may be very low, or where low temperatures may occur during periods when the unit is not operating, a sump located inside the building is the preferred means of ensuring that the basin water will not freeze. For these applications, the condenser will be supplied without the spray pump, suction strainers and all associated piping, but with an oversize bottom outlet. Electric Water Level Control Evaporative condensers may be ordered with an electric water level control in lieu of the standard mechanical float and make-up assembly. This package provides accurate control of water levels and does not require field adjustment. Coil Options Condensers may be supplied with multiple circuit coils to match various system requirements such as split systems, or if a glycol or water circuit is desired for compressor head cooling. Coils can also be executed in stainless steel without CROSSCOOL tube enhancement. Contact Evapco for capacity corrections.

Mounting holes, 19 mm in diameter are located in the bottom channels of the pan section to provide for bolting to the structural steel. (Refer to certified drawings from the factory for bolt hole locations.) Beams should be level to within 3 mm in 1,8 m before setting the unit in place. Do not level the unit by shimming between it and the I beams as this will not provide proper longitudinal support. A B Basin Heater Package If a remote sump configuration is not practical, electric basin heater packages are available to help prevent freeze-up of the basin water. The packages include electric heater elements, and a combination thermostat/low water cutoff. Note: External pumps should be heat traced and insulated in the field to prevent freezing. Electric Heaters Electric immersion heaters are available factory installed in the basin of the condenser. They are sized to maintain a +5 C pan water temperature with the fans off and an ambient air temperature of -18 C. They are furnished with a combination thermostat/low water protection device to cycle the heater on when required and to prevent the heater elements from energizing unless they are completely submerged. All components are in weather proof enclosures for outdoor use. The heater power contactors and electric wiring are not included as standard.

10 A P P L I C A T I O N APPLICATION Applications EVAPCO units are heavy-duty construction and designed for long trouble-free operation. Proper equipment selection, installation and maintenance is, however, necessary to ensure good unit performance. Some of the major considerations in the application of a condenser are presented below. For additional information, contact the factory. Air Circulation In reviewing the system design and unit location, it is important that proper air circulation be provided. The best location is on an unobstructed roof top or on ground level away from walls and other barriers. Care must be taken when locating condensers in wells or enclosures or next to high walls. The potential for recirculation of hot, moist discharge air back into the fan intake exists. Recirculation raises the wet bulb temperature of the entering air causing the condensing pressure to rise above the design. For these cases, a discharge hood or ductwork should be provided to raise the overall unit height even with the adjacent wall, thereby reducing the chance of recirculation. Good engineering practice dictates that the evaporative condenser s discharge air not be directed or located close to or in the vicinity of building air intakes. Engineering assistance is available from the factory to identify potential recirculation problems and recommend solutions. For additional information regarding layout of evaporative condensers, see EVAPCO Bulletin entitled Equipment Layout. Piping Condenser piping should be designed and installed in accordance with generally accepted engineering practice. All piping should be anchored by properly designed hangers and supports with allowance made for possible expansion and contraction. No external loads should be placed upon condenser connections, nor should any of the pipe supports be anchored to the unit framework. For additional information concerning refrigerant pipe sizing and layout, see EVAPCO Bulletin entitled Piping Evaporative Condensers. Bleed-off Each unit supplied with a pump mounted on the side is furnished with a clear bleed line for visual inspection and a valve which, when fully open, will bleed-off the proper amount of water. If the make-up water supplying the unit is relatively free of impurities, it may be possible to cut back the bleed, but the unit must be checked frequently to make sure scale is not forming. Make-up water pressure should be maintained between 140 and 340 kpa. Water Treatment In some cases the make-up will be so high in mineral content that a normal bleed-off will not prevent scaling. In this case water treatment will be required and a reputable water treatment company familiar with the local water conditions should be consulted. Any chemical water treatment used must be compatible with the construction of the unit. If acid is used for treatment, it should be accurately metered and the concentration properly controlled. The ph of the water should be maintained between 6.5 and 8.3. Units constructed of galvanized steel operating with circulating water having a ph of >8.3 or higher will require periodic passivation of the galvanized steel to prevent the formation of white rust. Batch chemical feeding is not recommended because it does not afford the proper degree of control. If acid cleaning is required extreme caution must be exercised and only inhibited acids recommended for use with galvanized construction should be used. For more information see EVAPCO Bulletin entitled Maintenance Instructions. Control of Biological Contamination Water quality should be checked regularly for biological contamination, If biological contamination is detected, a more aggressive water treatment and mechanical cleaning program should be undertaken. The water treatment program should be performed in conjunction with a qualified water treatment company. It is important that all internal surfaces be kept clean of accumulated dirt and sludge. In addition, the drift eliminators should be maintained in good operating condition. 10

11 Super Low Sound Technology on Evaporative Condensers PMCQ Condenser is now equipped with Super Low Sound fans to reduce the overall sound and SOUND improve the energy consumption by 50% compared to conventional centrifugal fan condensers. Ultra Quiet operation for Forced Draft Counterflow Evaporative Condensers 11

12 Solutions for Saving Energy and Sound Sensitive Applications S U P E R L O W S O U N D F A N T E C H N O L O G Y The NEW PMCQ Condenser comes standard with Super Low Sound Fans. They reduce the overall sound generation compared to forced draft centrifugal condensers, and additionally reduce the energy consumption by 50%. Consult EVAPCO's selection software for unit sound levels. If a detailed analysis or full octave band datasheet is required for your application, please consult your EVAPCO Sales Representative. SOUND Reduced Sound Levels and Reduced Energy Consumption versus Centrifugal Fan Units EVAPCO's Super Low Sound Fan on the PMCQ condensers utilizes an extremely wide chord blade design available for sound sensitive applications where the lowest sound levels are desired. The fan is one piece molded heavy duty FRP construction utilizing a forward swept blade design. Improved Sound Quality versus standard straight bladed axial fan types The SUPER Low Sound Fan on the PMCQ condensers reduces sound levels 10 to 13 db(a) and eliminates audible blade passing frequencies indicative of straight bladed axial type fans. Refer to the Narrow Band Spectrum graph which shows how straight bladed axial fans produce blade passing frequencies the same phenomena that produce the signature pulsating helicopter noise. The blade passing frequencies are audible spikes in sound pressure levels, but are not apparent in the octave band sound spectrum.

13 We Stand Tall Through it All! The International Building Code (IBC) is a comprehensive set of regulations addressing the structural design and installation requirements for building systems including HVAC and industrial refrigeration equipment. I B C With the advent of the IBC, EVAPCO is proud to introduce the new and improved line of PMCQ Condensers with IBC 2012 compliance standard. Wind, Rain, Earthquake and Hurricane EVAPCO Condensers designed to withstand seismic or wind load forces. 13

14 I B C C E R T I F I C A T I O N In its continuing commitment to be the leaders in evaporative cooling equipment design and services, EVAPCO PMCQ Condensers are now Independently Certified to withstand Seismic and Wind Loads in accordance with IBC I B C What is IBC? International Building Code The International Building Code (IBC) is a comprehensive set of regulations addressing both the structural design and the installation requirements for building systems including HVAC and industrial refrigeration equipment. Compared to previous building codes that considered only the building structure and component anchorage, the requirements contained within the IBC address anchorage, structural integrity, and the operational capability of a component following either a seismic or wind load event. Simply stated, the IBC code provisions require that evaporative cooling equipment, and all other components permanently installed on a structure, must be designed to meet the same seismic or wind load forces as the building to which they are attached. How Does IBC 2012 Apply to Condenser? Based on site design factors, calculations are made to determine the equivalent seismic g force and wind load (kilo-newton per square meter, kn/m 2 ) on the unit. The cooling tower must be designed to withstand the greater of either the seismic or wind load. All locations with design criteria resulting in a seismic design force of up to 1.0g or a wind load of 6,94 kn/m 2 or below will be provided with the standard PMCQ structural design. An upgraded structural design is available for installations with design criteria resulting in g forces greater than 1.0g. The highest g force location in North America is 5.12g. The highest wind load shown on the maps is 273 km/h, which is approximately equal to 6,94 kn/m 2 velocity pressure. Therefore, the upgraded structural design package option for the New PMCQ is designed for 5.12 g and 6,94 kn/m 2 making it applicable to most building locations all over the World. Design Implementation EVAPCO applies the seismic design and wind load information provided for the project to determine the equipment design necessary to meet IBC requirements. This process ensures that the mechanical equipment and its components are compliant per the provisions of the IBC as given in the plans and specifications for the project. Independent Certification Although the IBC references and is based on the structural building code ASCE 7, many chapters and paragraphs of ASCE 7 are superceded by the IBC, independent certification and methods of analysis are such paragraphs. Per the most recent edition of the code, the EVAPCO compliance process included an exhaustive analysis by an independent approval agency. As required by the International Building Code, EVAPCO supplies a certificate of compliance as part of its submittal documents. The certificate of compliance demonstrates that the equipment has been independently tested and analyzed in accordance with the IBC seismic and wind load requirements. Evapco has worked closely with the independent approval agency, The VMC Group, to complete the independent equipment testing and analysis. If the seismic g force or wind load requirements for the project site are known, EVAPCO s online equipment selection software, ies, will allow you to choose the required structural design package either standard construction or upgraded construction. For further questions regarding IBC compliance, please contact your local EVAPCO Representative.
