Transformer Cooling Fan

Transformer Cooling Fan for Transformer Radiator Banks — Forced-Air Cooling Solutions by Avantar

Avantar's Transformer Cooling Fan is an axial forced-air cooling system designed for transformers that are submerged in oil and power radiator banks. When the load on a transformer goes up, the core temperature goes up quickly, which makes the insulation break down faster. By adding an active cooling fan to the radiator bank, a lot of air is pushed across the fins, quickly getting rid of the heat and keeping the temperature inside the safe range. Most power supplies come with 230 V and 400 V, but you can ask for a different voltage if you need to. The goods are up to the standards set by CE, ISO 9001, and IEC 60076.

What Is a Transformer Cooling Fan?

An axial fan unit is a product that is directly connected to transformer radiator banks to speed up the cooling process when the load is high or at peak levels. The core temperature of a transformer rises quickly if it doesn't have continuous forced-air cooling. This makes the insulation last less long and makes it more likely to break without notice.

These cooling fans from Avantar are made to work nonstop in substations, factories, and renewable energy sites. Each unit moves air across the radiator fins, slowly removing heat and keeping generator temperatures within safe limits. The geometry of the blades is perfected to deliver the right amount of airflow while keeping the motor's power use in line with the fan size.

Key Features

High-Volume Airflow

The curve of the blades is perfect for moving a lot of air through the radiator fins so that oil-filled transformer radiator banks can meet their heat needs without making the motor too big.

Low-Noise Blade Shape

The form of the blades reduces aerodynamic turbulence, which in turn lowers the noise level. This is important for substations that are close to residential or business areas that may have noise limits.

Continuous Work in the Industry

Fan sizes are matched to motor sizes and optimised for thermal stability over long, continuous run cycles. This is necessary in substation uses where fans may have to work 24 hours a day, seven days a week.

Flexible Mounting

Units come in two different styles, bracket-mount and flange-mount, so they can fit a range of transformer radiator bank designs. You can ask for special safety covers if you want them.

Applications

Avantar's axial cooling fans are used across multiple industries and project types where transformer thermal management is required:

Technical Specifications

Motor and fan are supplied as a complete assembly. Mounting brackets and protective covers can be included as part of the package.

Custom Configuration Options

OEM and ODM customisation are both possible with Avantar. You can change the following settings to make them fit your transformer radiator setup:

Voltage

To fit the grid supply conditions in different countries, voltages other than the standard 230 V and 400 V can be made to order.

Level of IP Protection

You can choose the enclosure protection rating based on the site environment, such as whether it is indoors, outdoors, humid, or dusty.

Layout for Mounting

Depending on the shape of your radiator bank, you can choose between bracket-mount or flange-mount options. It is also possible to make your own fixing frames.

Volume of Airflow

The diameter and pitch of the blades on a transformer cooling fan can be changed to provide the right amount of airflow for your transformer's thermal load.

Power for the Motor

The motor power is based on the size of the fan and your temperature needs.

To ask for a custom configuration, send us the size of your radiator, the voltage at the site, and the weather. Before production starts, the engineering team will make sure that the technical specs are correct.

FAQ

Q: How does a product make a radiator bank work better?

When you put an axial fan right on the radiator bank, it pushes air across the cooling fins, which moves a lot more heat than natural convection alone. This keeps the core temperature of the transformer lower during high load, which protects the insulation from heat damage and makes the transformer last longer.

Q: Do you make things or do you trade?

A: Avantar is a direct manufacturer. In-house tasks include putting together fans, matching motors, and testing their performance. If you work directly with the manufacturer, you avoid having to pay markups to middlemen, and you can get a faster technical review for custom or project-specific needs.

Q: What kinds of custom factors are there?

A: You can choose the motor power, the operating voltage above 230 V/400 V, the IP protection grade, the mounting type (bracket or flange), and protective covers that are not required. Give the engineering team information about the site conditions, supply voltage, and radiator size so they can check the specs before production.

Q: What kinds of certificates and test records are given?

A: The products are in line with CE, ISO 9001, and IEC 60076. There is a proof of origin, material reports, and performance test records in every shipment. You can get a video inspection before the shipment, and for big projects, you can get a third-party witness inspection.

Q: What is the smallest amount I can order?

A: The minimum order quantity is one unit of each type. This is true for both standard configurations and units that are made to order. This makes it possible to find replacement units or try out a new configuration before committing to bigger volumes.
