Pressure from: 30 – 415 PSIG
Voltages from: 208 – 600 Volts

Theory of Operation

Vapor Power electric hot water generators are designed to provide fast, efficient, and economical hot water 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 water temperature. 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 boiler 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 to 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.

Applications

With over 100 years of experience in the industry and thousands of operating units, Vapor Power stands ready to assist with any specific application. Common applications include:
