Key Industries: Power Generation Refineries Petrochemical Pulp & Paper Applications: Cooling Towers Vertical Mixers Key Features: Designed specifically for cooling tower applications Spiral bevel and helical gears designed for low noise, low vibration operation Meets AGMA and CTI standards Marine grade paint standard (ISO C5-M) Sizes: Nine drive sizes with seven standard ratios from 8-16 Custom ratio and sizes available upon request Power range of 25 HP to 400 HP at a 2.0 Service Factor

3 Features and Benefits: Manufactured to American Gear Manufacturers Association (AGMA) and Cooling Technology Institute (CTI) standards. Double reduction spiral bevel gear units are designed for cooling tower installations and feature a tub and cover housing and pumpless lubrication. Oil is delivered to all requisite locations using an oil slinger in conjunction with an elaborate oil management system. Castings are designed and built to absorb internal and external loads with minimum deflection. Gear case and covers are designed to assure permanent alignment of bearings and gears under load. All casting materials are gray cast iron for effective damping of noise and vibration. Tub and cover housing design utilizes dowel pins to ensure proper alignment and is sealed using a formed-in-place gasket material that eliminates weeping. Spiral bevel gears are finished using a state-ofthe-art hard cut process, with special software monitoring to match the profile of the mating gears. The housing utilizes vertical fins to maximize thermal performance in high ambient temperatures such as those found in cooling tower applications with no additional cooling devices required. All bearings are roller-type, and sized to meet or exceed a minimum L 10 life of 100,000 hours as specified by AGMA and CTI standards. Standard marine grade paint conforms to ISO C5-M to ensure long service life in the harsh cooling tower environment. Low speed options are available for input speeds below 750 RPM. Standard accessories are available, including: Backstops Oil level switches Vibration switches Mechanical oil pumps Stainless steel ball valves Custom input and output shaft configurations, housing modifications, and other accessory options are available upon request.

10 Complementary Products and Services for Cooling Towers Addax Couplings Rexnord pioneered the first composite coupling, Addax, for cooling towers in 1987 to address problems with corrosion and reliability of steel couplings. Today, hundreds of thousands of Addax Composite Couplings have been installed around the world. For more than 25 years, Rexnord customers of Addax Couplings have benefitted from the reliability and design features of the composite couplings, including: 1/5 the weight of stainless steel or Marley couplings at the same torque ratings Corrosion and moisture resistance Ease of installation and retrofitting Lower total cost of ownership properly maintained, the couplings can last the life of the tower Addax Cooling Tower Brakes Plant personnel, fans, stacks and motors are kept safe. The Rexnord Addax Cooling Tower Brake requires no ropes, two by fours or lassoing of fans, and comprises additional features for added safety and control, including cross-pin locking, actuation, remote actuation and optimal proximity sensor for motor protection against locked rotor. Additionally, actuation features allow employees to be in direct control of fan freewheeling during maintenance. And in the event of high winds, your fan can be shut down in a matter of seconds, helping to reduce the time and expense to prepare for a plant lockdown. Additional features include: Critical components made from 316 stainless steel offer corrosion resistance Simple, low-maintenance design Universal mounting brake mounting position at 3, 6 and 9 o clock Naval brass fittings eliminate the potential for galvanic corrosion
