      Working closely with our clients to address their needs, our technicians provide an efficient response, supported by their training and extensive industry experience.

      • On-Site Maintenance

        • We perform repairs on transformers and their accessories directly at your facilities, backed by equipped mobile units and highly trained personnel.

      • On-Load Tap Changer (OLTC) Maintenance

        • Our department has specialized personnel to perform delicate cleaning, verification, and fine-tuning tasks on On-Load Tap Changers.

      • Oil Treatment

        • When transformer oil no longer meets the required conditions, oil treatment becomes necessary. At Tadeo Czerweny, we use purification equipment to clean and restore dielectric oil. This process improves its key properties, ensuring proper transformer operation and extending its service life.
