Frequently Asked Questions
What power range is available for electric steam boilers?
+General Boiler offers electric steam boilers and generators ranging from 20 kW to 500 kW. Our vertical stand-alone models are available in multiple configurations to match your facility's power requirements and steam demand.
What pressure ratings are available for electric boilers?
+We offer three pressure ranges: Low Pressure at 15 PSI for basic heating and humidification, Medium Pressure from 30 to 100 PSI for general industrial processes, and High Pressure from 100 to 250 PSI for demanding applications requiring higher temperature steam.
What are the advantages of electric boilers over gas fired boilers?
+Electric boilers produce zero emissions at point of use, require no fuel storage or chimney, have a compact footprint, and offer precise temperature control with lower maintenance costs. They are ideal for facilities where gas supply is unavailable or where emissions restrictions apply.
Are stainless steel electric boilers available?
+Yes. General Boiler offers both carbon steel and all stainless steel construction options. Stainless steel units are recommended for applications requiring clean steam, corrosion resistance, or compliance with pharmaceutical and food-grade standards.
What applications are electric steam generators used for?
+Electric steam generators are commonly used for autoclave sterilization in medical and laboratory settings, pharmaceutical manufacturing, food processing, commercial laundry operations, and industrial heating processes where clean, reliable steam is required.
Do electric boilers require special installation?
+Electric boilers require appropriate electrical supply matching the unit's voltage and kW rating, a water supply connection, and proper ventilation. Unlike gas boilers, they do not require a flue, chimney, gas line, or fuel storage — making installation simpler and more flexible in most facilities.
