The TH440 is a forced ventilation system developed for exclusive use in dry-type transformers. Its main function is to improve the thermal performance of the equipment, allowing an increase of up to 25% to 35% in the available power of the transformer, depending on the model and operating conditions.

This system is highly recommended in situations where additional power reserves are needed, such as during peak demand, or when the transformer is already operating close to its maximum capacity, helping to avoid equipment replacement. The increased cooling also contributes to extending the transformer’s service life.

Unlike generic systems, such as exhaust fans mounted on the cubicle ceiling, the TH440 directs the air flow precisely to the ventilation channels located between the medium and low voltage coils, ensuring efficient and localized ventilation.

Among its main features, the following stand out:

– Universal compatibility with any fan in the TH line, allowing replacements or upgrades without the need for adaptation or replacement of parts
– Simple and modular installation, allowing the customer to assemble the system with a few screws and easily adjust the position and angle of incidence of the fans
– Optimized efficiency through precise airflow direction, without the need for additional elements such as fins or external ducts
– Better use of the air intake flow in the fans, due to the absence of bulky obstructive parts
– Economical transport option, with the system supplied disassembled, allowing a reduction in volume of up to 50% in cases such as export or air transport

The TH440 can be purchased flexibly, according to the needs of each project. It is possible to:

– Request the complete system, ready for installation, with cables, fasteners, manual, and all accessories included
– Purchase only the bars or fans separately, as needed
– Receive the system assembled or disassembled, with detailed instructions for practical on-site assembly

The TH440 is the right choice for safely and effectively enhancing transformer ventilation in a cost-effective manner. It is widely used in the electrical sector to ensure greater thermal reliability in critical installations.
