The following diagram illustrates how to solve for watts, ohms, volts, or amps using Ohm's Law. Click to enlarge.

Fill in any two values to determine the other two:

°F = (9/5) × °C + 32

°C = (°F - 32) × (5/9)

Enter a value and select units to convert between

Calculate the electrical power, flow rate or temperature requirement as follows:

SCFM = airflow in standard cubic feet per minute

ΔT = temperature rise in F° from the inlet to the exhaust

Watts = SCFM x ΔT/3

Fill in two values to determine the third.

Three Phase Unit

Line Current = Wattage / (Voltage * √3)

Permaheat Strip

The Permaheat Strip heater is designed for heavy duty applications and is the most rugged strip heater we offer. It uses a tubular heating element to provide excellent heat transfer and resistance to contamination, and its aluminum body allows for better conformity to slightly irregular surfaces.
The tubular elements are placed in a precisely extruded aluminum base. The aluminum body also serves as an excellent transfer medium for rapid heat-up while providing a uniform temperature throughout the entire heater.
