Hazardous Locations are well defined by the National Electric Code (NEC®) for good reason. Choosing the wrong transformer for use in perilous environments containing volatile gases, dust, liquids or fibers can lead to serious consequences.
Our Silica Resin Encapsulated Transformer is the result of many years of continuous refinement. The Haz-Pac™ product type was initially developed and expanded as a result of a growing need for a compact and economical dry type transformer that was impervious to harsh environmental conditions, such as those encountered in chemical plants, refineries, dairies, marinas, shipboard use and desert areas like those found in Saudi Arabia, Africa, South America, North America, Australia, Asia, etc.
Product durability, quiet operation, and flexibility in designing the encapsulated style transformer for your application are clear advantages offered by the Olsun brand. Olsun Electrics’ Haz-Pac™ transformer line is designed and built specifically for hazardous locations in compliance with article 500 of the NEC and is UL* listed for Class I, Division 2, Groups C and D locations. And with a North American Temperature Classification of T3C, Haz-Pac™ keeps its cool under load — when you and the surroundings demand it. Couple our dedicated hazardous duty design with high short-circuit strength, 80° C rise availability and Olsun Electrics’ industry proven reliability and you’re literally playing it safe in choosing Olsun for long life in your application.
