For the laundry elements these fall into our open coil group of heaters. This is where the heated wire or open coil is exposed to open air versus being encapsulated inside the tube with our tubular group of heaters. In order to provide heat with the heated wire exposed to open air there are several key things that need to be provided.

First is the frame or wire support structure used to mount the components to secure the heated wire. Our facility is vertically integrated with the capability for metal forming, stamping, and cutting to supply our production line with metal structure components. Our default material used in galvanized steel for our open coil frames however other materials are available upon request.

Once the frame structure is complete the next component is the isolation supports that are used to touch and securely hold the heated wire during electrical operation. The isolation supports are held in place by the frame structure. Our isolation supports are made from ceramic materials designed to withstand the high temperatures generated from the heated wire. The shape of our ceramics resembles a “ram’s horn” shape.

The last item needed to complete the open coil heater assembly is the heated wire. The material that we use for the heated wire is a Nickel Chromium alloy comprised of 60% Nickel. This alloy structure provides the hot strength needed during electrical operation. Hot strength is the ability of the heated wire to conduct the electricity, provide the heat required in the form of wattage, and at the same time not droop or sag to touch either another heated wire in the circuit or part of the metal frame structure.

The electrical connections that are available include a quick connect type terminal, a hardwired connection with threaded terminals, or lead wires with either stripped ends or pre-installed crimped electrical terminals.
