For over 25 years, the dry type transformer marketplace has come to expect the best hazardous location low voltage transformers from Olsun Electrics Corporation, specifically the original Haz-Pac™ three and single phase transformer.
With its innovative bottom wiring compartment, hinged padlockable door and stainless steel construction, the Haz-Pac™ product has been the preferred and quality choice of customers and specifying engineers for their hazardous location and corrosive environment transformer applications.
Recently, Olsun Electrics’ SilPac™ encapsulated transformer was approved for inclusion into our UL E198883 hazardous location product file and into the hazardous location marketplace. The SilPac product features identical Haz-Pac™ high quality electrical core and coil design and encapsulated construction with various enclosure options; NEMA 4 mild steel, NEMA 4X stainless steel, floor and wall mount enclosures. With these and other available variations, Olsun can meet project application requirements from a product and pricing standpoint.
The SilPac™ is less expensive because it does not have the Haz-Pac™’s hinged padlockable wiring compartment door.
