Seiwa J350 H4-2 Band Heater

Seiwa J350 H4-2 Band Heater from Seiwa Denetsu is a wraparound heating element designed to fit around cylindrical surfaces for uniform heat transfer in industrial processing. It delivers 785 watts at 240 V AC, enabling targeted heating of components such as barrels, nozzles, and other round parts on molding and extrusion equipment. Band heaters of this style use a resistive element enclosed within a protective sheath and are clamped around a cylindrical heating zone to provide even circumference heating essential for consistent process temperatures. The J350 H4-2 designation identifies the exact model within Seiwa’s band heater lineup and specifies its electrical characteristics to support proper installation, circuit sizing, and safe operation within compatible systems, making it a suitable choice for integrating into existing plastic processing lines where reliable, steady heat is required.
