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)
Although the most common application for the Flextracoil is externally heating flow-through nozzles in hot runner systems, this heater is also versatile enough to be used for hot metal forming punches and dies, sealing bars and dies, instrumentation and medical applications.
Flextracoils can also be modified to meet the demands of virtually any special application. Our engineers can utilize a variety of alternative features and options to customize the heater to your specific needs. Each Flextracoil heater is warranted against burn-out and defects in materials and workmanship for a period of one year after delivery.
The square and flat designs have a broader surface contact and are recommended over the round design. For short coil widths, the square element is recommended because of its narrower width, which will allow for more turns per inch.
As mentioned before, the thermocouple is type "J". The thermocouple has been located 1/4" (6.3 mm) to 3/8" (9.5 mm) in from the tip of the element. This is due to the fact that when the heater is coiled, the tip does not conform to the coiling diameter. By moving it back, a more accurate reading is achieved.
