Cartridge Type Electric Heater with Thermocouple


Cartridge type electric heater with thermocouple structure: inside of cartridge heater has built-in temperature measuring element (index number can choose K, J, E or thermistor). This cartridge heaters can match with digital temperature controller to monitor and contro temperature. This type cartridge heaters are widely used in heating equipments which require strict requirement on temperature error, for example customer need to heat up quickly, then they can increase the electric power accordingly.


Features:

1). Usage: plastic molding mould, food packaging machine, glass machinery, woodworking machinery, environmental protection machinery, pharmaceutical machinery, oven class, electrical appliances accessories, etc.

2). Voltage: 12-440V.

3). Wattage: 6-25W/cm² (Effective heating area surface area).

4). Cartridge heater has the characteristics of heating up fast and its working temperature is 1200 ? or less.


Cartridge heater performance index:

1). Temperature rise time: under test voltage, the component from ambient temperature to test temperature should be less than 15min.

2). Rated power deviation: the deviation of the rated power of the element shall not exceed the specified range of the following provisions under sufficient heating conditions.

3). The components with rated power of 100W are: ±10%. The components rated power greater than 100W are: + 5% ~ -10% or 10W (take the larger value of the two).

4). Insulation resistance: factory inspection cold insulation resistance shall be not less than 500 m O, hot insulation resistance is not less than 50 m O.


Cartridage heater design and customization:

1). Voltage and Wattage.

2). Size of pipe diameter: it can be 3-35mm according to customer's requirement.

3). Length of pipe body: non-standard customization (minimum 15mm).

4). Material of pipe body: the main materials are SUS304, SUS321, SUS316L, 840, 800, 600, stainless steel

Coating (anti-scale treatment), SUS310S, titanium tube, teflon, etc.

5). Material of electric heating wire: generally iron chromium aluminum wire (Beijing shougang) or nickel chromium wire (2080 resistance wire).


It depends on the working environment (temperature and vibrativeness) and the surface power load of the heating pipe itself.

The regular tubular electric heating element standard is 6-8w/cm2, and the power load in the special working environment is not more than 25W/cm2.

6). Other: working environment, terminal column or lead length (standard: 300mm), whether the flange is required (thread size), the diameter and length of the metal hose and so on.


Cartridge heater precautions for use:

The components are allowed to work under the following conditions:

1). Air relative humidity is not greater than 95%, no explosive and corrosive gases.

2). The working voltage shall be no more than 1.1 times the rated value and the enclosure shall be effectively grounded.

3). Insulation resistance = 1MO  and dielectric strength: 2KV/1 min.

4). The heating tube shall be fixed in position, and the effective hot zone must be completely immersed in liquid or metal solid. When the surface of the tube has scale or carbon, it should be cleaned and cleaned in a timely manner so as to avoid heat loss and shorten the service life.

5). When heating easy molten metal or solid nitrate, alkali, leached and stone wax, the voltage should be reduced first and then the rated voltage can be reached after the medium is melted.

6). When heating air, the elements should be aligned evenly, so that the element has good heat dissipation
