Product Overview
For large connected loads and round-the-clock production, oil cooling offers better heat dissipation and a longer service life. Voltainer oil cooled servo stabilizers house the variac and buck-boost transformer in a transformer-oil filled tank, with the control electronics and bypass switchgear in a separate panel.
They are the preferred choice for dusty, hot or humid sites — textile mills, plastic processing, RMC plants and mining operations.
