Company Announcement - With the P4 and M4ACC gear units fully customised to the specific needs of the cooling tower industry, global industrial gearbox designer, manufacturer and supplier, Hansen Industrial Transmissions (HIT), offers truly functional solutions for wet cooling towers and air cooled condensers. The overall design of these gear units fully complies with the Cooling Tower Institute specifications.
For the wet cooling tower drives, HIT now offers a range of 11 bevel helical Hansen P4 gear unit sizes up to 108 kNm, which allows a more accurate selection. They are all well protected for operation in a very humid environment. The increased distance between the propeller and the high speed input shaft reduces vibrations. A motor can be connected to the outside of the cooling tower using an all-metal disc coupling at the high-speed shaft.
Based upon P4 technology, a dedicated design for the Hansen M4ACC gear units with six helical unit sizes from 24 to 66 kNm has been developed. Applying the same high quality standards, this gear units range offers a cost solution with optimised gear geometry for lower noise levels. The monobloc concept insures higher stiffness of the housing. As a standard, these units come with a lantern housing that allows for connection of a motor on the top of the gear unit.
