In the chemical industry and metal smelting industry, since the 1980s, with the development of power electronics technology, a variety of complex, precise, power quality-sensitive electrical equipment is constantly popularized, people have higher and higher requirements for power quality, so more and more power quality equipment is put into use. Similarly, with the penetration of power electronics technology, microelectronics technology and modern control theory into the field of AC electric drive, as well as the promotion of national energy conservation policy, high-voltage and high-power frequency converter has been widely promoted and applied. As an important part of HV frequency converter, water cooling system can effectively solve the heat dissipation problem of HV frequency converter, provide constant temperature environment for HV frequency converter, and ensure the system stability, safety and reliability of HV frequency converter. With the increasing power density of HV inverter, the traditional cooling technology can not meet the requirements of heat dissipation of HV inverter. The HV inverter water cooling system, due to its high heat dissipation efficiency, strong environmental adaptability, low operation and maintenance costs, is bound to replace the traditional cooling technology, in the HV inverter cooling industry occupies a dominant position.

The power quality control and electric drive cooling devices manufactured by Joule Tech are suitable for the cooling requirements of various voltage levels and different types of high-power power electronic devices, and can be specially designed according to the requirements of users.This type of equipment can be matched with power electronic equipment such as: high voltage converter, static var compensator (SVC), static synchronous compensator (STATCOM), Thyristor Controlled Series Compensation (TCSC), flexible AC transmission system (FACTS),etc. The key equipment of the cooling system adopts redundant configuration to ensure long-term stable operation of the system.

Joule Tech also provides oil cooling system of different heat exchange equipment for transformers, combining with the site situation of end users, to provide users with the best solution.
