Channel Heater
A nickel chromium resistance wire is strung through and supported by a ceramic core. Finely meshed refractory material is vibrated through the remaining air voids to provide good thermal conductivity and dielectric strength. The sheath is seamless stainless steel and with proper surface contact and application considerations can provide sheath temperatures to 900°F/485°C. Because of ease of installation, Proheat Channel Heaters have been used in many industrial applications, such as platens, hot plates, dies, molds, mill slots or any place surface heat is required. Figures TF2 and TF3 can be used as air heaters or in oven applications.
