The capacitors offered comply with the latest EU standards and cover a wide range of technical applications. They are specially tailored to the requirements of energy-intensive induction processes and offer high technical performance, flexibility in installation, certified safety and long-term operational efficiency. This makes them an ideal solution for companies that rely on modern and reliable components in the field of melting and heating technology.
By combining technical expertise, customer-specific advice and a quality-tested product portfolio, TCT Tesic offers a comprehensive solution for industrial applications in which capacitors play a key role.

Product overview and areas of application
The range includes a wide variety of capacitor types with different technical characteristics. The available product categories include:
- Water-cooled medium and high-frequency capacitors: Particularly suitable for induction systems that require high performance combined with efficient heat management.
- Medium and high-voltage capacitors: For applications with increased voltage requirements.
- Low-voltage capacitors: For less complex systems with standard requirements.
- Surge protection capacitors: Protective components to prevent system damage.
- Energy storage capacitors: Specifically for applications that require fast charging and discharging cycles.
- APFC panels (Automatic Power Factor Correction): For optimising the power factor and reducing reactive power in power grids.
The products have a modular design and can be flexibly integrated into various system configurations. Possible applications range from foundries with induction furnaces to other industries that require powerful capacitors for special switching and control technology.

Optimisation of induction performance
The use of these capacitors contributes significantly to improving the performance of induction systems. They ensure a stable power supply, minimise network interference and increase the efficiency of melting processes. Especially in systems with high power requirements, the use of specialised capacitors is a key factor in optimising overall performance and operating costs.
Compared to conventional standard components, the capacitors offered provide optimised thermal stability, higher switching cycle stability and a user-friendly design that facilitates integration into existing systems.
Customised solutions and service
In addition to its standard product portfolio, TCT Tesic also offers customised solutions. Based on individual requirements, the company works with its partners to develop tailored capacitor solutions that are precisely matched to the operational conditions. This includes not only the technical design, but also aspects such as space requirements, cooling technology, connection configurations and safety features.
Technical advice and support are a central part of the service concept. Customers benefit from comprehensive support – from needs analysis and product selection to commissioning and maintenance.
Certified quality and European standards
All capacitors offered comply with the applicable European standards for electrical equipment. Manufacturing is carried out in compliance with international standards and using modern testing methods that ensure compliance with high quality and safety requirements. This is particularly relevant for companies that operate in a regulated market environment or are required to use products with CE marking.
