High−Density Cartridge Heaters

High density cartridge heaters distinguish themselves by their high compression and therefore especially efficient heat emission. That's why we produce them with a ground surface for a H7 fit. The resistance wire is spooled on a ceramic core as shown on the photograph. Afterwards the space between wire and cartridge sheath is filled with MgO. Finally the cartridge is swaged and thus compressed. Advantage of this construction is the resistance wire's short distance to the sheath, the resulting very good heat emission and the excellent control response.

Standard connection(s)
Type I
Electric contact is made "Inside" the cartridge heater (max. lead length uncoupled 1000 mm up to Ø 8 mm) Advantage: flexible termination area

Type N
The Normal electric contact is made outside the cartridge heater and is protected by a silicone impregnated fibre glass sleeve Advantage: cheap production, length of the lead freely selectable

Type F

Ø	3/8'' 10 mm	1/2'' 12,5 mm	5/8'' 16 mm	3/4'' 20 mm
T [mm]	5	6	7	8

Flexible version of the outside contacted "normal" connection type N
Advantage: Connection is protected from bending in a ceramic cap, can be manufactured of stock cartridge heaters, length of the lead freely selectable

Standard leads:

250 mm fibre glass insulated nickel leads (up to 300 °C permanent temperature resistant)
for High-Density Cartridge Heaters Ø 4,0 mm PTFE leads (up to 260 °C permanent temperature resistant)
