pow erful solutions for cooling tow ers andair cooled condensersc o o l i n g t o w e r■HANSEN M4 ACCHELICAL GEAR U NITBased upon Hansen P4 and Hansen M4 technology, a dedicated design has beendeveloped. Applying the same high quality standards, this gear unit offersa cost efficient solution with optimisedgear geometry for lower noise levels.The monobloc concept ensures higherstiffness of the housing. As a standard, these units come with a lantern housing that allows for connection of a motor on the top of thegear unit.This model is used mainly in air-cooledsteam condensation plants which areideal in dry environments where waterresources are scarce. The cooling fan’smotor is located in the air stream of the air-cooled refrigerant condenser. ■HANSEN P4: BEVEL HELICAL GEAR U NITFor vertical housings, the extendedbearing span of the low speed shaft hasbeen standardised to meet the particularneeds of the cooling tower industry: the extended bearing span increases thedynamic stability of the gear unit. The increased distance between the propeller and the high speed input shaftreduces vibrations. A motor can be connected to the outside of the coolingtower using an all-metal disc coupling atthe high-speed shaft.i n d u s t r yCOOLING TOWERS COOLING TOWERS COOLING TOWERS F O R A N O V E R V I E W O F W H A T ’S A V A I L A B L E , C H E C K O U R C O M P R E H E N S I V E L I T E R A T U R E W I T H R E F . 4 1 5 - 2 2 0■HANSEN P4: SMALL IS BEAU TIFULThe Hansen P4 "Z – B" range catersfor 3 sizes available in two differentassembly arrangements, with or withoutextended bearing housing at the lowspeed shaft.With nominal power ratings up to 180 kW at 1500 min-...
