An open coil electrical resistance heater subassembly for use in a heater has a support plate dividing the heater into at least two portions. At least two resistance wire coils are supported on the support plate using a plurality of insulators. Each insulator is configured to provide support to a portion of the resistance wire coil. The at least two resistance wire coils are arranged with respect to the support plate so that the coil power for each coil is distributed generally evenly between the top and bottom of the support plate and across the width of the support plate.
In an open coil electrical resistance heater subassembly having a support plate dividing the heater into at least two portions, at least two resistance wire coils, a plurality of insulators mounted to the support plate along a defined path, each insulator configured to provide support to a portion of the resistance wire coil, the at least two resistance wire coils partitioned generally equally on each side of the support plate, the at least two resistance wire coils each having first and second coil ends with a lead extending from each of the first and second coil ends, wherein each of the first and second coil ends are located at one end of the support plate, the improvement comprising the at least two resistance wire coils are arranged with respect to the support plate so that the coil power for each coil is distributed generally evenly between the top and bottom and across the width of the support plate.
