Quick calculation: for a required power P (W) at voltage U (V), the total resistance is R = U²/P and the wire length ≈ R / 1.8462 m. Contact us before ordering to select coil diameter, pitch and surface load; we can also quote ready-wound coils or complete heating elements.
Resistance, weight and surface values are calculated at 20 °C from the manufacturer's resistivity and density; resistance rises somewhat at operating temperature (Ct factor). The manufacturer datasheet prevails for exact values.
