Cartridge heaters - Import export

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.

CSN ® Explosion proof cartridge heaters as direct heaters for liquids or gases in hazardous environment. These units are equipped with a heating bundle or a replaceable ceramic heating element. For temperature control these heaters are available with an integrated temperature monitoring system. These devices are available in various material grades. The electric cartridge heating element type 93./..EEx….T.(.) is designed for the heating of liquids in the zone 1 and zone 2. The standars elements, mentioned in this list are suitable for DGRL (code 2014/68/EU) Art. 4, Para. 3. The elements can be suited (on request) to other uses requiring another classification according to DGRL Further information about our CSN® ExCartridge Heater

CSN®cartridge type heating elements and bath heaters are eminently suitable for direct heating and warming of liquids of all kinds. Corresponding to the nature of the different media protective coverings of steel, various special steel types or porcelain can be selected. The electric heating inserts of CSN®cartridge type heating elements may be installed or dismounted without the necessity of draining the liquids from the container. The CSN®cartridge type heating elements and bath heaters are manufactured for nominal voltages from 110 up to 690 volts D.C. and A.C. In the case of higher heating capacities 3 or more elements each, being individually divisible by the factor 3 can be star or delta connected to 230 and 400 volts A.C. threephase mains. At 12 kW and a related length the elements are fabricated for 400 volts A.C. threephase delta connections. In any case the desired voltage and type of current has to be stated.

Uses in plastic industry: The infrared technic thermography can be used in plastic industries to optimize the process and improvement of quality, as well as in the development of new tools. In the thermoplastic injection process, can be found wide information about the transformation process itself:

Maxiwatt High Load cartridges, which have been have proven themselves for 50 years successfully performing in thousands of applications applications that very few manufacturers are currently manufacturers are currently capable of producing, have a maximum temperature of 1000º.

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

They are especially designed for quick adaptation in molds or surfaces where the use of rivets either causes problems or impossibility to use. Cuadrawatt cartridges are the better choice. Cartridges with a low density of watts are most recommended for moderate heating up to a maximum temperatures of 300ºC. The square tube is made of prime quality stainless steel. All the tubes are perfectly calibrated both inside and outside, into which a long-life ceramic piece is inserted. The tube resists a continuous temperature variation and has the best possible thermal conductivity, as the ceramic piece is in contact with the wall of the tube, which makes the most perfect heat distribution possible. Special Cold Sections: Distributed Wattage Single Circuit Element Independent Heat Zones Three Phase Element Dual Voltage Designs Thermocouple A,B,C RTD Elements Thermostats

The exclusive manufacturing design guarantees a precise temperature distribution throughout the plastic filament, melting it all at the same time. Only the thread of the nozzle is heated, where the casting process has to be produced. We only produce Cylinder Heater Core with different volts, watts and control systems, we do not include hot ends.

The expandable cartridge Heaters solve two major problems with conventional high density heaters , poor durability and proper fit extraction improving the accuracy of the temperature with hundreds of attachments and exits for all kind of processes . With the expandable cartridge heaters we join for the first time the best of the common cartridge heater with cartridge and an adaptive tuning quick and easy removal.

Square cartridge heaters are used where much power has to be installed near the surface of a tool, e.g. in cutting knives, sealing stations or hot plates. With a soft, malleable condition in stainless steel or nickel sheath square cartridge heaters can easily be pressed into common milled rectangular grooves. Apart from the advantageous heat transfer over ¾ of the sheath, it is not necessary to cement or cast in the heater which is imperative for round cartridge heaters. Unlike tubular heaters which are also available in square sections (see chapter Flexible Heating Pipes), the square cartridge heaters have the termination on one side and can be loaded with 16W/cm² (2.5W/in²) due to their special inside construction.
