Circulation Heaters

Circulation heaters consist of either a screwplug or flange immersion heater mounted on a pipe vessel. These complete units are designed to heat flowing liquids or gases. Ideal for side-arm or in-line applications, the medium being heated is directed past the heating elements, allowing for quick response, even heating distribution, and accurate process temperature control.

Each assembly is equipped with:

• Heating element
• Inlet/outlet connections
• Insulated pipe vessel
• Terminal enclosure
• Mounting Blocks
• Drain Plug

Circulation heaters are easy to install and maintain with minimal time and labor due to their compact size.
