Spiral finned heaters are offered in copper-brazed and tight-wound designs. Brazed fin heaters are made with steel fins helically wound and copper-brazed around a tubular heating element. They typically are painted with high-temperature aluminum paint. Standard applications include dryers, ovens, duct heaters and other forced-air applications where the maximum operating temperature is less than 750oF (399oC). The tight-wound spiral finned heaters are made with stainless steel fins helically wound around a stainless steel tubular heating element attached by two brazed connections at each end of the fin. The tight-wound units are intended for applications where the operating temperature is between 750 and 1,200oF (399 and 649oC).
