Vapor - Model STR - Electric Steam Boilers - Brochure

Vapor Power electric steam boilers are designed to provide fast, efficient, and economical steam for heating and process through the use of electric resistance elements. The boiler controls automatically energize/de-energize steps of elements to maintain the desired steam pressure. All boilers utilize ASME pressure vessels and all electrical components are UL listed and are wired in accordance with the current National Electrical Code requirements. Each generator is insulated with 3-1/2″ fiberglass secured to the vessel, and is housed in a heavy-gauge sheet metal cabinet mounted on a full size structural steel base. All Vapor Power resistance style boilers utilize 70-75 wpsi Incoloy-sheathed elements configured in conservatively sized circuits to allow for overvoltage conditions as great as 10% without adversely affecting the integrity of circuit components.
