PERFORMANCE CURVES
SERPENTINE II ELEMENTS
The performance curves on the following pages show exit air temperatures at different airflows and
voltages. Pressure readings (longer dashed lines) are measured at the inlet to the heater with no
entrance or exit restrictions. Solid lines indicate safe, normal-life operating conditions. The shorter
dash lines indicate marginal, shorter-life operating conditions leading to premature burnout. With
a known flow (or pressure) at the heater entrance, follow the flow (or pressure) line across until it
meets the desired temperature curve. Drop a line straight down to intersect the x-axis. This point,
along the “Heater volts – true RMS” axis, represents the voltage required to generate the desired
exit air temperature at the chosen flow rate (inlet pressure).
