Transformer Cooling Fan for Data Centre — Manufacturer & Supplier
Vayuvents Pvt. Ltd. manufactures and supplies transformer cooling fans for data centre applications across India and export markets.
Data centres are among the most power-critical facilities in modern infrastructure — requiring transformer cooling fans with exceptional reliability, low acoustic noise, and ability to operate continuously without maintenance intervention in the air-conditioned environment of a data centre electrical room.
Data centre transformers include the main HV/MV intake transformer, multiple UPS bypass transformers, and generator step-up/step-down transformers — all of which require ONAF cooling fans matched to their specific cooling class rating.
Vayuvents supplies transformer cooling fans for India's fast-growing data centre sector — with hyperscale and enterprise data centres in Mumbai, Chennai, Pune, Hyderabad, NCR, and Bengaluru all requiring highly reliable power infrastructure including transformer cooling systems.
How It Works in This Application
Transformer Heat Generation
Data centre transformers operate at high, consistent load factors (70 to 90 percent of rated capacity) — generating continuous heat that requires sustained ONAF cooling.
ONAF Cooling Activation
ONAF fans activate via OTI/WTI thermostat when transformer temperature reaches the setpoint — typically at 90 percent load or during high-ambient conditions in the transformer room.
Low-Noise Operation Requirement
Data centre electrical rooms are often located within or adjacent to occupied spaces — requiring low-noise fan operation to meet building acoustic standards.
High-Availability Operation
Data centre power infrastructure requires 99.99 percent uptime — transformer cooling fans must be highly reliable and fan failure alarm must trigger immediate response.
Recommended Variants
Low-Noise Radiator Fan
Optimised blade design for low acoustic output — critical for data centre electrical room noise compliance.
Most RecommendedRedundant Fan Array
N+1 or 2N fan configuration where failure of any single fan does not reduce cooling capacity below required level.
Temperature-Controlled Fan
Fan with integrated PT100 or thermocouple temperature sensor and controller for precision temperature-based speed control.
Enhanced IP Rating Fan
IP65 rated fan for transformer rooms with higher humidity or water spray risk.

FAQs
Data centre electrical rooms typically require transformer cooling fan noise levels below 65 dB(A) at 1 metre to comply with building acoustic standards and ensure acceptable noise levels in adjacent occupied spaces. Vayuvents provides measured noise data for all transformer cooling fan models and can specify low-noise variants for data centre applications.
Data centres implement N+1 or 2N fan redundancy where failure of any single fan does not reduce cooling capacity. Fan failure alarms are wired to the DCIM (Data Centre Infrastructure Management) system for immediate notification. Vayuvents recommends keeping spare fans on-site at all times for immediate replacement, and provides fan selection that allows N+1 fan arrangements on the transformer radiator bank.
Data centres monitor transformer cooling fan status (running/stopped/failed) as part of the DCIM system. Each fan motor should have a current monitoring relay that detects motor failure. Vayuvents can supply fans with motor current monitoring relay contacts wired for connection to the DCIM or BMS system for real-time fan status monitoring.
Yes. Variable frequency drive (VFD) control of transformer cooling fans allows speed reduction during partial-load periods (typically nights and weekends in commercial data centres), significantly reducing fan power consumption. VFD-controlled cooling also reduces motor thermal stress and extends fan life. Vayuvents supplies VFD-compatible motor windings for all transformer cooling fan sizes.
Vayuvents transformer cooling fans with factory-sealed bearings and IP55 motor enclosures are designed for 80,000 to 100,000 hours of continuous operation (approximately 10 to 12 years) in normal data centre electrical room conditions. This is achieved through premium-grade bearing selection, tight motor manufacturing tolerances, and consistent quality control in our Vasai manufacturing facility.
Yes. Vayuvents supplies transformer cooling fans for all data centre tiers including Tier III (N+1 concurrently maintainable) and Tier IV (fault tolerant) facilities. We provide the documentation required for MEP design review including fan noise data, power consumption, and airflow performance curves.
