grills, toaster ovens and storage heaters. For suspended coils in
air heaters in clothes dryers, fan heaters, hand dryers.
NiCr 35/20:in braking resistors,industrial furnaces.In
night-storage heaters, convection heaters, heavy duty rheostats and
fan heaters. For heating cables and rope heaters in defrosting and
de-icing elements, electric blankets and pads, car seats, baseboard
heaters and floorheater.
NiCr 30/20:in solid hot plates, open coil heaters in HVAC systems,
night-storage heaters, convection heaters, heavy duty rheostats and
fan heaters.For heating cables and rope heaters in defrosting and
de-icing elements, electric blankets and pads, car seats, baseboard
heaters, floor heaters and resistors.
