Specifications

Heater Element

(See Nichrome Calculator)

Notes:

  • Fiberglass sleeve used - HTG fiberglass, does not fray like standard high temperature sleeving (1000F) and is rated for . See [1]. Note that the resin can burn out at the 650C (1200F) workign temp. Sleeve has VW-1 flame resistance. Made of fiberglass, it does not burn out, but may fuse and lose fiber structure.
  • Inner core: 5' long wraparound of 2mm tight braid fiberglass sleeve - 600C - [2]
  • This is packed into 6' of 6 mm tight braid fiberglass sleeve.

Heater Optimization
