375 High-Temperature Strip Heaters

รายละเอียด Named for its 0.375 in. (9.5 mm) thickness, the rugged Watlow 375 strip heater is capable of both high temperatures and high watt densities.
Watlow begins construction by accurately placing a coiled, nickel-chromium element wire in the center of the heater. The element wire is then embedded in magnesium oxide (MgO)-based insulation compacted into a solid mass creating excellent heat conductivity and high dielectric strength. The heater is then enclosed in aluminized steel or 430 stainless steel sheathing.
Features & Benefits Nickel-chromium element wire is centered in the heater assures uniform heat
Aluminized steel sheath operates at higher temperatures and resists corrosion
Optional 430 stainless steel sheath meets temperature requirements that reach up to 1200°F (650°C)
Over 100 in-stock models in popular sizes and ratings for next-day shipment
UL® approved to 240VAC (File No. E52951) and CSA approved to 600VAC (File No. LR7392)
