Power//Flow Rate//Temp Calculator
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

Line Current = Wattage / (Voltage * √3)
Permaheats can be used in many different situations, including heating barrels of extrusion and injection molding machines, especially in areas where contamination is possible.
In addition, Permaheats can be modified to meet the demands of special applications. There are a variety of alternative features and options available to customize the heater to your special needs.
Straight threaded terminals are normally supplied on all Permaheat heaters.
Terminal box protects employees from possible electric shock. High temperature braid or stainless steel can also be ordered for further protection. (Aluminum terminal box is standard).
High temperature ceramic insulated quick-disconnect plug mounted in a terminal box allows quick and convenient connection. Female quick-disconnect plugs are also available.
For applications requiring leads, high temperature mica tape (842°F, 450°C) lead wire is attached.
