аrt.64
The ETMA URTM-1x2-I U1 (hereinafter referred to as the equipment) is designed for the regeneration and filtration of used transformer oils. The unit also prepares a 20% ionol solution, which is then injected into the transformer oil. When equipped with a thermal vacuum treatment (TVT), the equipment also provides oil drying.
