| Sheath Material |
Max. Safe Sheath Temperature |
Suggested Applications |
| Copper | 350º F | Immersion in water or other solutions which will not corrode copper and are capable of withstanding high watt densities. |
|
Steel |
750º F | Immersion in molten salt or soft metals (special low ratings in watts/sq. in. required) - Immersion in oil, alkaline and vapor cleaning solutions (special low ratings in watts/sq. in. required for oils of high viscosity) - Low temperature air heating - Clamping or wrapping to metal surfaces - Cast into aluminum |
| Stainless Steel | 1300º F | Cast into aluminum - Air heating at high temperature - Clamping or wrapping to metal surfaces - Immersion in liquids where non-corrosive sheath is required - Immersion in some molten salts and soft metals |
| Incoloy | 1600º F | Air heating and in slightly corrosive immersion applications |
We can recommend a specific sheath material for an application, and believe that it should prove satisfactory. However, we can assume no liability for heaters against damage, leakage, or short life resulting from corrosion, electrolysis, misapplication, improper specification, or other conditions beyond out control.
