Totally enclosed non-ventilated (TENV) transformers are an excellent choice for applications where dry type transformer benefits are desired but the standard enclosure openings are unacceptable because of adverse atmospheric conditions. TENV transformers are recommended where dust, dirt or lint may be present or where transformers are subject to sprays or controlled wash down conditions. They are UL Listed through 75 kVA for indoor or protected outdoor applications. TENV transformers meet NEMA TP-1 efficiency.
