Fluid Circulation Heaters

Heatrex Circulation Heaters are complete packaged units designed to control the heating of water, oils, steam, air and other gases.

Construction

Heater Assembly - The heat source is of a bolted flanged design. This consists basically of metal sheath tubular elements, formed to a hairpin shape which are welded or silver brazed into a standard steel pipe flange. A NEMA 1 electrical terminal enclosure is standard. Heater Chamber - The inner pipe body of the heating chamber is constructed of type A-53 or type A-l 06 carbon steel pipe which is sized to accept the bundle diameter and length of the required heater assembly. One end of the heating chamber is sealed by welding a pipe cap to the body; a slip-on flange which mates with the pipe flange of the heater assembly is welded to the opposite end. Inlet and outlet connections are fitted into properly located cut outs in the pipe body and are welded into position. The heating chamber is insulated completely with fiberglass and enclosed in a sheet metal outer housing. Exterior and nonmachined surfaces are finished with rust inhibiting paint.

Circulation Heater Controls

Heatrex Circulation Heaters provide the user with an extremely efficient heat source which is readily adaptable to the control requirements which suit his process. When combined with properly selected controls, these heaters function with accuracy and economy of operation.

The selection of controls or a control system for a specific application or process should be based on the careful consideration of a number of factors including:

• Heater selection of proper size and type
• Acceptable range of temperature above and below desired set point
• Medium used for heat transfer
• Fluctuations of temperature due to variables in the process
• Over temperature protection requirements
• Operator requirements such as readability, control monitoring, etc

Heatrex application engineering personnel are available
to assist in the evaluation of your control requirements.
