Marathon introduces TEAO cooling tower motors with BCP

September 16, 2015 | By Renée Francoeur

September 16, 2015 – Marathon Motors recently introduced a new line of totally enclosed air-over (TEAO) cooling tower motors with BCP—Bearing Current Protection—using AEGIS Shaft Grounding Rings.

These motors feature BlueChip-quality, 100% cast iron construction for rigidity and reduced vibration, Marathon Motors claims. With internal and external epoxy paint, sealed bearings, T-drains in both endshields for effective drainage, drive-end bearing isolators with shaft slingers, and fully gasketed conduit boxes (with lead separators), they are IP56 rated and built to withstand the harsh environments of cooling towers.

Designed for 10:1 VT or 20:1 CT operation with a variable frequency drive, the motors have Max Guard Class F insulation and are equipped with AEGIS Bearing Protection Rings installed internally.
