ISH Steam Superheater

Model ISH Electric Steam Superheaters

High Efficiency. And Fast.

Precision Model ISH electric instantaneous circulation heaters are custom designed to provide high efficiency and quick response heating of liquids and gases.

Key Advantages

• Models for heating air (IAH), oil (IOH), steam (ISH), or water (IWH).
• Stainless steel, incoloy, or copper sheathed heating elements
• Custom selected components to fit the application
• Reduced voltages to fit heating capability to the fluid

Special Element

NOTE: Overall length is equal to the element length (2x element length for 2-flange models) plus 10″. *Complete model number requires heater type prefix element number insertion, and heater rating and design pressure suffixes. Example: Model ISH-862-0035-250ST represents a steam superheater configured with an 8″ tank, (21) 1.67 KW elements operating at 17wsi, (2) element flanges, a total rating fo 35KW, and designed for 250psi max. steam pressure. **Max number of elements can be reduced in increments of 3. *Series connection. **Wye connection.
