Chromalox Process Air Heater - Finned - .315" Dia. Single End Fintube® Heater SFTS-315

The Chromalox SFTS-315 is a .315" diameter single-end Fintube® heater designed for process air and radiant heating applications. It features a steel sheath and is available in wattages ranging from 325 to 2,400 watts, with options for 120 and 240 volts. The heater operates at a maximum sheath temperature of 750°F and has a watt density of 60 W/in². This heater is particularly suitable for applications where space is limited, such as drying, heat treating, annealing, load banks, and curing ovens. The design includes continuous spiral fins that enhance heat transfer efficiency, allowing for lower surface temperatures and the potential for fewer heating elements in a given area. The unit comes with 10" long lead wires and is constructed to simplify wiring with single-end terminals. Engineers should consider the SFTS-315 for its versatility and efficiency in various industrial heating applications, especially when space constraints are a factor.
