Coil Heaters

SPECIFICATIONS AND OPTIONS
Engineering Specifications
Standard sheath material 304 stainless steel
For temperatures up to 1500°F (815°C)
Optional sheath material Inconel® 600 up to 1800°F (980°C)
For aggressive atmospheres
Standard thermocouple ANSI Type J
Optional thermocouple ANSI Type K
Minimum bending radius Three times the sheath diameter

VINAYAK coil heaters feature continuous operating temperatures up to 1200°F (649°C). Rapid heating and cooling occur, due to the low mass construction. All heating elements are sealed from contamination and the stainless steel sheath provides maximum corrosion resistance. An optional internal thermocouple may be utilized for overtemp control.
