Radial dry type snail fan features

In the air-cooled dry-type transformer provides maximum solutions. Cross throw and radial fans are a product designed to cool the heat generated by the transformers and increase the operating performance of the transformer. All solutions used in order to provide maximum energy sector.

Cross flow Cooling Fan

The large air flow increases 45% -60% of capacity, allowing the dry-type transformer to dissipate heat completely.

Dry Type Transformer Fans

Various cooling fans are available upon customer request. Cooling fans vary according to impeller diameter, airflow inlet and housing material. Aluminum alloy and stainless steel enclosure is optional.

The air flow is blown into the air duct of the high and low voltage winding of the transformers and the coil and iron core at a certain angle (which greatly increases the effective air flow for heat dissipation).
Compact structure of the cooling fan with 220 volts 50/60 Hz supply voltage, stylish appearance and easy installation.

Air flow inlet and outlet channels are equipped with a protective mesh door to ensure safe and reliable operation.

Motor winding insulation H class.

Fan components and material characteristics
The ARS-FC double suction cross flow fan is highly efficient and low noise. Made of high-quality corrosion-resistant galvanized steel. The motor and fan impeller are connected to the body via an aluminum bracket. The outer rotor motor is compact and has a maximum delivery air temperature of 40°C.
Fan structure
The forward-inclined impeller is made of high-quality corrosion-resistant galvanized steel and has an aerodynamic structure to ensure stable airflow. Thanks to its aerodynamic airfoil structure, the fan runs quietly.

GF series cross-flow cooling fans for dry-type transformers (hereinafter referred to as: dry-transformation cooling fans) are mainly used for dry type transformer cooling capacity increase and electronic equipment, power distribution cabinet, high and low voltage switch cabinet and other products cooling and cooling. Using this series of cooling fans can increase the output power of dry-type transformers by 40-50%, which can greatly improve the The load-carrying capacity of type transformers and prolong the service life of dry-type transformers are widely adopted by domestic and foreign manufacturers.

When the GF series cooling fan is used in a dry-type transformer, the fan is placed on both sides of the lower part of the transformer coil to cool it. The wind is directly blown into the transformer coil, high and low voltage cooling air duct, and the heat dissipation effect is obvious, which can protect the normal operation of the transformer and prolong its service life.
