We support the customer to minimize such downtime by our global service network, quick supply of spare parts, quick correspondence and repairs and etc. Hansen P4 gearbox Powerful solutions for Wet Cooling Towers and Air Cooled Condensers Many industries are using steam, water or other cooling fl uids that need to be cooled down for reuse of the fl uid in the process or for temperature limitations on waste water. Typically cooling tower users can be found in power generation plants and in the chemical industry. In environments where water resource is regularly present, the ‘wet’ cooling tower principle will mainly be used. In dry environments where water resources are scarce, Air Cooled Condensers (ACC) are ideal. Hansen P4 gearbox Hansen M4 ACC Helical gearboxes, dedicated for air cooled condensers In an air cooled condenser, hot water or steam is guided through a closed circuit. A fan pushes the air through a huge heat exchanger. The cooling fan is typically driven via a vertical gearbox with parallel shafts. Features and advantages ? Specifi cally developed design offers a cost effective, robust & effi cient solution. ? Dedicated monobloc housing – available in 6 sizes. ? Torque range from 20 to 70 kNm and a wide range of reduction ratio’s. ? Optimized gear geometry for maximum load capacity, minimum losses & lower noise levels. ? Designed in accordance with the Cooling Tower Institute (CTI) specifi cations. ? Standard leakage-free drywell construction at the low speed shaft. ? No external piping, easy to install. ? Lubrication insured at windmilling conditions. ? Reference to dedicated selection method taking starts and stops into account. ? More than 10,000 installations in the fi eld. Optional hydraulic brake system (patented) The unique brake design for Hansen M4ACC gear units allows the user to safely slow down the gear unit and condenser fan, and keep them at standstill during maintenance activities in dry cooling towers. This way we offer a tool to avoid the risk of maintenance personnel being injured due to windmilling. The Hansen M4 ACC drives are specifi cally designed for Air Cooled Condensers in dry environments where water resources are scarce. As a standard, these units come with a lantern housing, allowing an alignment free connection of a motor on the top of the gear unit. Hansen P4 gearbox Hansen P4 Right angle gearboxes, for wet cooling towers and air cooled condensers In a Wet cooling tower, hot water is sprayed inside a relative small tower. The air is pulled through the tower with a fan driven via typically a vertical gearbox with right angle shafts. With the Hansen P4 gear units, fully customized to the specifi c needs of the cooling tower industry, we offer a truly functional solution for wet cooling towers. Also for air cooled condensers that need a right angle drive solution, the Hansen P4 gear units are a perfect fi t. Features and advantages ? Dedicated vertical housing – available in 11 sizes. ? Torque range from 2.6 to 100 kNm. ? Reduction ratios from ratio 3.55 – 22.4. ? Extended bearing span of the low speed shaft increases the dynamic stability. ? Optimized lubrication system for very low operating speeds and windmilling conditions. ? Designed in accordance with the Cooling Tower Institute (CTI) specifi cations. ? High resistance to corrosive and extreme humidity environments. ? Low noise and vibration levels. ? Standard optimal sealing system, designed to keep the oil in and dirt out. ? ATEX Available. Hansen P4 gearbox RIGHT ANGLE GEARBOXES, DEDICATED FOR COOLING TECHNOLOGY Hansen M5CT Overview ? Vertical Right Angle 2-stage industrial gearbox series. ? Specifically designed for Cooling Technology applications: – Wet Cooling Tower fan drives – Air Cooled Condenser fan drives. ? Dedicated product: cost efficient, robust & easy to maintain. ? Available in 7 sizes (13-53 kNm). Hansen matches the drive to the application and offers proven reliability under the most severe conditions. ? Carburised and ground gearing of both bevel and helical gears excels in strength, torque capacity, surface durability and low noise performance ? Large overhung load capacity of the gear unit. ? A wide range of bearing and flange configurations meet any application requirement, while still providing a cost effective solution. ? Bearings and shafts are dimensioned to go the distance, ensuring long bearing life under heavy loads. ? Extended bearing housing combining the effects of an increased shaft diameter and extra space to mount larger bearings, and adds rigidity and stability to the mixer drive under load. ? A wide range of mounting and centring possibilities. ? Increased diameter of the low speed shaft: the allowable bending moment on the low speed shaft increases. ? Continuous oil circulation through the bearings ensures a long, trouble-free working life for the gear unit. ? Hansen’s unique Oil-Lock and Oil-Guard systems offer a maintenance-free sealing on high-speed shaft extensions as a standard. ? The drywell, available on all models, prevents oil leakage on vertical down shafts. ? The internal construction of the gear unit housing allows for simple and complete oil drainage. ? The larger units can be easily inspected and serviced on the spot, thanks to covers above the oil level. ? One-stop-shopping for complete drive package solutions. ? In-depth engineering support and complete documentation before and after the order. ? Hansen’s global service capability significantly reduces downtime. Hansen P4 gearbox Dedicated industrial gearbox Best possible fit for Wet Cooling Towers and Air Cooled Condensers (induced draft types) ? Designed in accordance with CTI standards Manufactured to be compliant with Cooling Technology Institute (CTI) specifications ? Best out of Hansen P4, Hansen M4ACC and PARAMAX SFC Rely on decades of experience and more than 20.000 installations in the field ? Rigid housing, dynamic stability Smooth transition of high axial loads coming from the rough application ? Optimized gearing from Hansen P4 range Proven design, maximum load capacity, minimum losses and quiet operation Technical Information ? Advanced design to withstand the peak fluctuations during start-up Selection method taking starts and stops into account, specifically for ACC applications ? Reliable lubrication and sealing, less maintenance Oil lubrication without outsides pipes, Oil seal hood for reliable protection against the ingress of dust & water ? High resistance in corrosive and extreme humidity environments Standard high-quality paint conform ISO C5 corrosion category, stainless steel bolts, use of durable instruments ? Numerous instruments & accessories E.g. Optional condition monitoring: Temperature, oil flow and vibrations Hansen P4 gearbox
