Construction - Cartridge HEATERS | PHK series
Cartridge heaters from Herbst Beheizungs-Technik consist of a ceramic heating element inserted into a protective steel tube. The tubes have a welded-in or hard-soldered bottom and a thread nipple on connection side for screwing into tanks or plants. The cartridge heaters are equipped with a hood and cable connection.
The ceramic heating element can be removed without having to drain the process media.
We recommend to weld a sleeve into the tank or plant as the most suitable way for the mounting of the heaters. We deliver ready for installation, along with the matching seal.
The cartridge heaters are constructed for horizontal installation. The fluid level must always be higher than the position of the heaters. Otherwise the elements or the medium can be damaged by overheating.
The tube material (steel or stainless steel), hood (zinc-plated or stainless steel) and thread nipple (steel/stainless steel/brass) must be chosen according to the particular application.
