Expandable barrel heater

Designed to expand and slide over the barrel, a new heater band enables bands to be installed and removed from any point along a barrel without removing heaters and thermocouples, simplifying installation. One-piece barrel bands can pose difficulties in removal, but the HTFlex Band expandable model eliminates those difficulties, and it doesn't require any assembly and wiring for two-piece bands. The HTFlex supports operating temperatures up to 1400F and watt densities up to 90W/inch. IMS Company, Chagrin Falls, OH; 440-543-1615;
