Cartridges with high watt density. They provide a great uniform distribution of heat, and are hermetically manufactured, which considerably increases the long life of the resistance as well as preventing the oxidation of the heating wire even at high temperatures. Over 25.000 measurements in high density cartridges available. High density Maxiwatt cartridges are manufactured from prime quality materials and undergoing the strictest safety controls, according with international standards. -Long-life -High temperatures -Maximum watts capacity 60w/cm2

Screw-in heaters are versatile and intended for heating liquid media in industrial and commercial applications. When selecting, the specific surface load permitted for the respective medium must be observed and checked by the customer. EHK G2 are mainly used for heating hydraulic oil in containers in which the replacement of the heating cartridge without draining the medium must be possible. Ceramic heating cartridge in stainless steel tube ø 50mm, material-no. 1.4512 or material-no. 1.4404. G2″ thread SW70 welded from V2A. Terminal box made of PA6-GF30, impact-resistant and oil-resistant, degree of protection IP66/67. Unheated zone 50mm, surface load 1,5 W/cm², voltage 230/400 V. Special versions on request.

Occasionally also these terms are used for cartridge heates: heating cartridge, insertion heaters, spiral cartridge heaters. As a rule cartridge heaters consist of a cylindrical stainless steel tube and thus provide a high corrosion prevention. There is a heating wire inside which is wound onto a ceramic core. The number of coils varies depending on the power. In order to avoid a short-circuit, the cartridge heater is filled with magnesium oxide and compressed afterwards. Highly compacted they reach a surface watt density of up to 50 W/cm² and withstand highest stress. In the plastics industry cartridge heaters are used in hot runners in order to temper thermoplasts during injection moulding processes. Other areas of applications for process heat are e. g. packaging, diecasting or continuous casting in which zinc or aluminium are processed. Further applications are to be found in mechanical as well as medical and laboratory engineering.

Aramid fibers are suitable for very demanding applications and they are widely used in the firefighting industry (manufacturing of firefighters’ clothing) because of their flame retardant properties. Aramid is not only fireproof, the aramid fibers also have a high tensile strength, which is why they are often used for bulletproof vests (military and police) or for armoring selected emergency vehicles. A special property of aramid nonwovens is its good thermal insulation. The laid heating wire creates a very high heat output, which is insulated by the nonwoven. Aramid has a high heat resistance, which is an enormous advantage since laying the heating wire generates a very high heat output which is further enhanced by the insulation provided by the aramid nonwoven carrier. In addition, the nonwoven is either not combustible or flame retardant and can be used for a temperature ranges of up to 200°C.
