Immersion heaters are made of brass tubes (diameter from 10 to 60 mm). A tube serves as a protective coat. Heating spirals (made of high-alloy resistance wire) lie in steatite ceramics notches and are coated with silica sand. Length of the connectors/plugs is custom-made, the highest power allowed is 15 W/cm2.

Structure of the immersion heater
Brass or prochrome pipe with a diameter from 6.5 to 60 mm surrounds and protects the heating helix, which is made of strongly alloyed wire resistive to high temperatures. The heating helix is set in the grooves of a steatite ceramic and surrounded by quartz sand. There is a welded flange at one end, with a thread (1/2, 3/4, 5/4, 6/4 inches) up to the diameter of 35 mm, or is protected by a plastic housing. The length of the connector is defined by order and has a maximum allowed power rating of 15 W/cm 2 .
All of the main characteristics of a desired heater (voltage, power, diameter, length of the tube, length of the connection, for two-sided connections also whether wire or screw connection, data on rims) have to be specified in the order.
The immersion heaters 5/4 and 6/4 now also with the flange from prochrom (stainless) material!
