Transformer Cooling Fan Motors

Specialised Fan Motors for Power Transformer Cooling

Transformer Cooling Fan Motors are purpose-built three-phase induction motors that drive the cooling fans on large power transformers, ensuring radiator surfaces maintain heat-rejection performance under full-load and emergency overload conditions. Designed for outdoor operation in extreme weather, these motors must run reliably for years with minimal maintenance.

Bombay Engineering Syndicate supplies Crompton transformer cooling fan motors used by power utilities, distribution companies, industrial captive power plants, and EHV substation operators. Specifications match transformer manufacturer requirements: typical ratings 0.37 kW to 2.2 kW, low-noise design, hot-dip galvanised hardware, and TEFC enclosure with IP55 protection minimum.

Construction features include heavy-duty cast-aluminium or cast-iron frames, sealed permanently-greased bearings for 40,000+ hour life, marine-grade paint systems for coastal/humid environments, integrated condensation drain plugs, and weatherproof terminal boxes with hot-dip galvanised cable glands. Class F or H insulation withstands ambient temperatures up to 55°C.

BES supplies transformer fan motors as both new-build OEM orders to transformer manufacturers and as direct-replacement units to utilities/maintenance contractors. We coordinate with original motor nameplate data for precise drop-in replacements. Pan-India delivery through Mumbai and Ahmedabad warehouses.
