For over 20 years, Southern has been making the most reliable geared speed reducersdesigned specifically for cooling tower service.
The reliability of the Geareducer comes from more than 10, 000 units of experience, and from Southerns attention to exacting quality standards of design and manufacturing. Today, every Southern Geareducer is tested under load at our factory. Then, its inspected and adjusted before shipment.
Southern has always known that outstanding Geareducer engineering is only as good as the lubricant that protects it. Thats why we took the next step and filled every System 5 Geareducer with Southern Gearlube lubricant.
In addition, Southern has made several improvements in the System 5 Geareducer to take advantage of the extraordinary lubricating properties of Gearlube. The new Series Geareducer models will utilize a long-life lip-type oil seal at input shaft for extended service life.
Weve equipped it with a magnet in the sump to trap metal particles generated during initial break-in period

Our splash fill bar advances the state of the art in cooling tower splash fill.
Enhanced thermal performance of Omega fill increases cooling tower capacity in most all cases. Variable fill bar spacings provide the required thermal performance with the minimum amount of fill material and installation time. Omega fill is installed parallel or perpendicular to the air flow depending on thermal performance requirements or existing cooling tower configuration.
Fill bars are extruded of corrosion resistant PVC (polyvinyl chloride) manufactured by Southerns plastics facility. The unique material formula used in the splash bar meets or exceeds CTI Standard 136 for strength, flammability and impact. Each bar is firmly attached to FRP or stainless steel fill grids with unique injected molded polypropylene benches designed to prevent premature wear on the fill bar and the grid.
Our Splash bars classic arch shape enhances structural characteristics which prevents sagging, even after prolonged exposure to cooling tower environments.
Our fill and its support system are designed to be used in virtually all cooling towers regardless of a cooling towers age or manufacturer.
outhern anti-fouling film type fill consists of thermoformed corrugated sheets made of rigid polyvinyl chloride (PVC), impervious to decay, fungus and biological attack. The sheets are bonded to form modules which can be dimensioned to fit any application.Our Film fill combines properties related to a medias ability to allow substances to migrate through it, while maintaining thermal efficiency this then allows for the use of film fill where fouling risks occur.Each module consists of vertically channeled flat and corrugated surfaces, which essentially avoids contact between the sheets, thus eliminating water concentration. The horizontal corrugations and their location within the sheet promote optimum mixing of air and water. The flutes in the fill are vertically and aerodynamically shaped resulting in a reduction of pressure drop.
GridLoc splash-fill support is a polypropylene injection molded support for use in crossflow towers. The GridLoc design has a pair of integral, opposing, downward sloping splash bar grips attached to the vertical strands in each window to secure splash bars. The lower horizontal strand has a short pair of vertical nubs to center splash bars and provide a nonabrasive support that eliminates the need for bench supports.
The GridLoc design has a molded in shelf support at the top of the grid for attaching the grid to the structural members. The grid can be either nailed or screwed to the support member to avoid movement of the grid in the horizontal plane.
The typical GridLoc arrangement will be in 4 x 6 bays with bars parallel to air flow. The nominal window opening for bar spacing is 4 horizontal by 8 vertical. The GridLoc splash bar grips are compatible with many Southern splash bar designs as well as commercially available bars. GridLoc will retrofit on historic Southern towers.
Southern developed the cellular drift eliminator in the 1990s. No other eliminator could come close to our eliminators low drift rate and low pressure drop.
Now, virtually every eliminator is a nesting cellular PVC type design. Our Eliminators are more advanced design that meets or exceeds todays demanding specifications for drift emissions without sacrificing fan horsepower
The eliminator discharge angle is important enough to warrant two separate eliminator designsone for crossflow and one for counterflow towers. Tests show the air direction leaving the eliminator is extremely importantimperfect designs create additional work for the fan.
This means either increased fan horsepoweror reduced cooling tower performance. The crossflow version features drainage slots within the eliminator pack to insure trapped drift is returned to the wet side of the cooling tower.
Low drift rate is the primary goal of eliminator design. Our Eliminators boasts typical drift rates of .005% of the total GPM. Lower drift rates are available depending upon tower configuration.
Southern eliminators require little or no maintenance. If it becomes necessary to clean them, care must be taken not to physically damage the PVC eliminator packs. For loose deposits of silt, fibers, etc., a water spray can be used, provided the spray nozzle is kept moving continually and the water pressure is not excessive
The orifice sizes of Southern nozzles are large enough that many competitive nozzles will actually fit inside a Southern nozzle. Southern counterflow nozzles have no internal parts or narrow passageways. The attached diffusion ring will not retain even fibrous debris.Full cone distribution pattern assures uniform water distribution for all film fills. Minimal spray overlap is required, providing uniform water distribution even near spray boundaries. Southern counterflow nozzles develop uniform water distribution over a wide range of operating water pressures.
Crossflow NozzleThe Southern nozzle is used only on splash-fill crossflow towers where objects in the water supply create blockage in smaller nozzles.Southern Nozzles are injection-molded, highimpact black polypropylene. Each nozzle is a single assembly with no moving parts.The nozzle is the ideal solution for overflowing basin problems due to clogged nozzles
The Southern Spiral Target nozzle is an injection molded polypropylene unit consisting of two partsthe main body with integral target diffuser and a snap-on insert or orifice cap.
The orifice cap is available in different sizes. This amount of flexibility allows for a wide range of adjustment in water flow rates and basin water levels.
The Spiral Target nozzle is available in three lengths. Different size Nozzles are used on wood, steel, and fiberglass cooling towers where basin support structure does not obstruct the release of water. Nozzles are used on larger industrial wood and concrete cooling towers and on applications where clogging might be a concern.
In every application the target portion of the nozzle should be located at the correct distance above the top of the cooling tower fill to obtain maximum water distribution over the fill area. misalignment.
gearreducer, gearbox, gear-box, gear bearings, lubrication, gearlube, gear-lube, reducerSouthern industrial Geareducers are manufactured and designed specifically for cooling towers in large industrial and power plant applications. In shape and function, their design goes beyond normal AGMA requirementsboth to maximize air movement through the tower, and to minimize the impact of maintenance.Although the primary function of a Geareducer is to reduce the speed of the driver (usually an electric motor) to a speed which is conducive to good fan performance, it must satisfy other criteria as well. For example, it must provide primary support for the fan withstand the shock loads imposed at start-up and during subsequent speed changesanchor the fan against lateral movement in response to rotational forcesand contribute as little as possible to power transmission losses as well as the generation of noise.
Given these requirements, many manufacturers of mechanical equipment provide acceptable speed reducers. Designed for more forgiving commercial applications, these units are often unprepared for the rigors and peculiarities of cooling tower service, such as the corrosive effects of operation (often intermittent) within an exceedingly humid environment. As a result, both the life expectancy of these commercial speed reducers and the thermal performance of the cooling towers on which they are installed often suffer.Southern is the major manufacturer whose Geareducers are designed uniquely for cooling tower service. And, since we warrant not only the Geareducer, but the thermal performance of the cooling towers on which they operate as well, development, design, and manufacture are taken very seriously. This has resulted in an unequalled history of trouble-free operation.
The driveshaft transmits power from the output shaft of the motor to the input shaft of the Geareducer. Because the driveshaft operates within the tower, it must be highly corrosion resistant. Turning at full motor speed, it must be well balancedand capable of being re-balanced. Transmitting full motor power over significant distances, it must accept tremendous torque without deformation. Subjected to long term cyclical operation, and occasional human error, it must be capable of accepting some degree of misalignment.Driveshafts are described as floating shafts, equipped with flexible couplings at both ends. Shafts are fabricated of tubular stainless steel or carbon fiber. The yokes and flanges which connect to the motor and geareducer shafts are HDG steel or stainless steel.
It is very important that driveshafts be properly balanced. Imbalance not only causes tower vibration, but also induces higher loads and excessive wear on the mechanical equipment coupled to the shaft. Most cooling tower driveshafts operate at speeds approaching 1800 rpm. At these speeds, it is necessary that the shafts be dynamically balanced to reduce vibrational forces to a minimum.
Southern fans are designed specifically for industrial cooling tower applications, offering distinct advantages over other types of fans. The Southern Flare Tip blade enhancement provides increased performance overcoming tip clearance losses, aiding the movement of air next to the fan cylinder.
The wide blade design is well suited for low noise operation, delivering superior air flow and pressure capability at reduced speed.
The skin of the fan is made with top-quality fiberglass reinforced vinyl ester that is infused with pigment for even distribution across the laminate. There are multiple layers of surface veil on the blade surface leading to superior UV protection compared to fans with only a painted exterior.
Constructed in one continuous piece, with a consistent moment weight, Fan blades are interchangeable without the need to rebalance the fan assembly. A nylon leading edge erosion barrier is molded into each blade to ensure long service.
The hollow blade is designed with a deep section airfoil making the Fan strong, yet light and easy to handle
