Totally enclosed non-ventilated transformers are highly suited for applications where the atmosphere contains conductive, corrosive, or combustible materials which might damage a transformer, or lint and dust which might block the ventilation passages. With no openings in the enclosure, heat is dissipated by radiating from the surface area of the enclosure.
