HALF & FULLY SHEATHED RING HEATERS

HS / FS Ring Elements owing to their convenient shape & sizes, adapt themselves readily to variety of machines and appli-ances for which other type of heaters are not suitable. They are being fitted for heating platens, dies of presses. They are also in use for melting of glue, wax, easily fusible metals like leads, tin, solder, hot plates, valves, flanges, brooders, vulcaniz-ers, popcorn machines, high speed packing machines, diffusion pumps, tank bottoms, kettles, large coffee percolators & wash boilers etc.  

Being sheathed on one side only, it has very little residual heat and stands up to 650°C temperature for its surface area. Elimination of the sheath on the contact side puts the rock hard refractory in direct contact with the heated surface, thereby providing slightly faster heat-up. Half Sheath elements can be used where the protection provided by the full sheath is unnecessary.

Chrome steel sheath on one side and edges, other flat side is the bare refractory. Coiled electric resistant wire embedded inside. And steel terminal studs with nuts and washers

Fully Sheathed Heaters (both sides metal) provides extra protection from rough handling & usage, especially when there are chances of falling any liquid on it.
