  • Open coil electric resistance heater with offset coil support and method of use
    Patent number: 7947932
    Abstract: An open coil electrical resistance heater uses a number of offset insulators to support the coil of the heater. The offset insulators configure the run of coil in a sinusoidal shape to hold the insulators in a more secure manner and reduce vibration and noise generation during heat operation. The sinusoidal configuration of the coil also reduces the problem of shadowing of portions of the resistance wire coil.
    Type: Grant
