DescriptionThe SST and QST Split Sheath Insertion Heaters are designed especially for platen, die or mold heating applications where the holes are poorly drilled or worn through age. Independent expansion of each section of the SST and QST when energized, creates intimate contact with the wall of the hole. Split Sheath design can Improve conductive heating and quickly insert and removed from long holes. Incoloy® Sheath gives long life at extreme temperatures with compacted to maximum density for the excellent element to sheath heat transfer and dielectric strength Flexible Leads - SST & QST are available with flexible lead wires machine connected to the terminal pins, for temperatures to 850°F(450°C). 12” length is standard. Specify a longer length.
