Heating cartridges standard design SNHP
Uncompressed heating cartridges
The maximum surface load is 4W/cm², yet this version represents a cost-effective alternative to the high-performance cartridge.
Construction:
The spirally rolled heat conductor NiCr 8020 is drawn into the ceramic multi-hole tube (carrier material). The spaces are filled up with high-quality magnesium oxide. The cartridge bottom is flanged and soldered if required.
