Low Temperature Plug Heaters
Low temperature plug heaters are used in low temperature forced air circulation heating systems in heating ducts and other industrial heating equipment including baking and drying ovens.
TRENT low temperature plug heaters are compact, pre-packaged units that install quickly and have a long life with a maximum operating temperature of 750°F / 399°C or exhaust end temperature of 650°F / 343°C. Multiple banks of TRENT Folded and Formed® heater racks are assembled, wired and mounted in a self contained plug with handles, complete with an un-insulated steel flange top with gasket, a terminal box with leads mounted for electrical connections, all drilled and ready for quick installation.
The heater racks consist of a fabricated aluminized steel support frame with pre-formed metal channels into which high-grade, refractory, porcelain retainers are inserted to support one to four levels of three-tier high TRENT F&F® heating elements. The unique F&F® heating elements ensure faster heat-up, faster cool-down and more efficient use of heat to prolong the heater life. There are no screws or mechanical fasteners used in the rack frame construction. The internal connections are all welded. The anchor and terminal sections are welded to ensure continuous non-arching, electrical resistance path from terminal to terminal.
