Cartridge heater with uneven power distribution

This heater is internally divided into sections that emit different power values P1,P2,P3... Minimum section length is 50mm. Uneven power distribution enables higher or lower temperature at ends, or cold zone in the central section of the heater.

Cartridge heater with extended cold zones

Values of cold zones Lm1, Lm2 are different from standard values. The extended cold zones are recommended where the power connection is exposed to excessive temperatures or where it is required that the heater is hot over a specific length.

Cartridge heater with a mounting bush

The heater is fitted with a threaded bush to securely mount the heater in the hole, or if liquid is heated up, to set the heater in the tank wall. It enables a quick and tight-fitting installation of the heater in the hole The threaded bush has a hexagonal flange, which makes it easier to remove the heater from non-clearance holes. Bush materials: carbon steel, brass, stainless steel.

Cartridge heater with stripwound hose (steel braided, silicon jacket)

The stripwound hose is made of spirally coiled steel strip. The steel braiding is the most flexible protection for the connection wires.

The shield protects the connection wires against mechanical damage and damage from sharp edges. They facilitate cable running in the environment which can easily damage the connection wires.

Silicon jacket protects connection wires against moisture, oil, cleaning agent and fume contamination.

Code Type of connection
OW stripwound hose connected axially
OO steel braid, connected axially
OS silicon jacket connected axially
KW stripwound hose, angular connection
KO steel braid, angular connection
KS silicon jacket, angular connection

 

Axial connection

Depending on the heater diameter, there are two ways to connect the stripwound hose (metal braid or silicon jacket):

The stripwound hose (steel braid or silicon jacket) is mounted directly on the heater with a clamping bush - applies to heaters with diameter D <= 12,0mm Intermediate bush is welded to the heater, with the stripwound hose (steel braid or silicon jacket) connected to it with the clamping bush - applies to heaters with diameter D >= 12,5mm

Length of clamping bush LTz = 10mm
Length of intermediate bush LTp = 7 - 8 mm

 

Angular connection

The angular connection is designed to facilitate the heater connection.

Angular shield is soldered to the heater with the stripwound hose (steel braid or silicon jacket) connected to it. A copper elbow is soldered to the heater, on which the stripwound hose (steel braid or silicon jacket) is clamped with the intermediate bush.

Power connection directly from the heater is protected by high-temperature insulating jacket. Power connection protected with stripwound hose, silver soldered directly to the heater. Power connection protected with steel braid, clamped on the intermediate bush.

Conical cartridge heater

The heater diameter is tapered conically, 1:50. The conical shape of the heater ensures a precise fit with the hole. Good heat distribution depends on precise fit, so here the risk of overheat is mitigated.
